Internship content 1. Baotou Steelmaking Plant On November 5, we visited the steelmaking plant.
Baotou Steelmaking Plant is one of the important secondary factories under Baotou Steel. It not only produces steel products needed by various markets, but also undertakes the task of providing raw materials for other secondary factories and mines of Baotou Iron and Steel Co., Ltd. After entering the factory building, we climbed up the stairs and saw two large converters. Baotou Steel currently has two 210-ton converters. The 210 converter steelmaking project is a key national construction project in the "Ninth Five-Year Plan". It is Baotou Steel's thin slab continuous casting and rolling As a supporting project of the project, it undertakes the task of providing high-quality molten steel for Baotou Steel's new thin slab continuous casting and rolling production line.
According to reports, the converter equipment used in the project was American equipment imported by Shougang in 1994 for the construction of Shandong Qilu Iron and Steel Company. It was transferred to Baotou Steel due to the cancellation of the Shandong project. Baotou Steel's converter is a set of high-tech converter equipment. Among them, Baotou Steel's converter dry dust removal project has obvious energy-saving and environmental protection effects, making Baotou Steel's circular economy construction take a new step.
When the Baotou Steel Sheet Plate Plant was completed and put into operation, the dust removal method in the steelmaking process was wet dust removal. As the international steel industry and corporate environmental awareness increased, wet dust removal had weaknesses such as high energy consumption and unsatisfactory environmental protection effects. Gradually exposed and gradually replaced by mature dry dust removal technology. Baogang Steelmaking Plant was established in 1954. Initially, experts and technology were introduced from the former Soviet Union. It has three open-hearth furnaces and three converters.
At the end of 2000, the plant stopped the last open-hearth steelmaking, and dismantled all the open-hearths three years ago, using converters to make steel. There are currently 7 converters.
5 continuous casting machines. The current main steel products are: steel for heavy rail, steel for oil casing, etc.
The main cast steel billets are: bloom billet, large round billet, small billet, small round billet, molten steel pouring method. In addition to continuous casting, partial mold casting is also used according to customer or actual needs. The principle of steelmaking is to use oxygen or iron oxides to remove excess carbon and other impurities contained in pig iron into gas or slag under high temperature conditions.
The essence of smelting pig iron into steel is to appropriately reduce the carbon content in the pig iron, remove most of the harmful impurities such as sulfur and phosphorus, and adjust the content of alloy elements in the steel to within the specified range. The main reaction principle of steelmaking is also the use of oxidation-reduction reaction at high temperature. 3. Internship report on lifting bag section of Chenggang Steelmaking Plant is urgently needed
Please refer to:
Internship Report on Ironmaking and Steelmaking Plant
July 17, 2005 , with enthusiasm in their hearts, five students from the Metallurgy Class 034 boarded the train to the Baotou Iron and Steel Group Corporation in Baotou City, Inner Mongolia. Everyone was very happy and excited, almost walking over laughing and eating.
Around 11 a.m. on the 18th, we arrived at Baotou West Railway Station smoothly, and under the guidance of an alumnus, we found the good hotel he had found for us in advance - Baogang Staff The third guest house.
On the 19th, we officially started the observation practice and interviews of the trip to Baotou Steel.
First, we visited the Baotou Steelmaking Plant. At about 8 o'clock in the morning on the 19th, a van sent by Baogang Ironmaking Plant took us to Baotou Steelmaking Plant. According to previous contacts, we first found the director of the steelmaking plant, who is also an alumnus of our University of Science and Technology Beijing—Director Hao Zhizhong. But unfortunately, at this time, Baotou Iron and Steel Group Corporation was conducting an overall campaign to maintain the advanced nature of party members. Education, so all leaders are very busy. Therefore, the arrangement of our activities was handed over to the factory director by Director Hao.
Under the arrangement of Director Qi, we first visited the blast furnace operation of Baotou Steel No. 3 Steelmaking Plant. During visits and interviews with workers at the Baotou Steelmaking Plant, we learned that the Baotou Steelmaking Plant has four blast furnaces with a capacity of 7,426 cubic meters. Among them, the No. 4 blast furnace is a modern large-scale blast furnace newly built in the 1990s. Regardless of its safety The steel production is still very advanced, with a diameter of about 10.5 meters, and steel is produced about 18 times a day. Although it is not the most advanced in the world, its performance in all aspects is more than sufficient for a medium-sized enterprise like Baotou Steel. .
Leaving the noisy and hot blast furnace of the ironworks, we walked to the main control room to the south of the blast furnace. As soon as we entered the main control room, we immediately felt a cool and comfortable feeling of escaping from the sea of ??fire. Moreover, the worker who led the team quickly got a bottle of mineral water for each of us. We sat next to the computer, drank the cool water and looked at the monitor. Only then did I realize how hard the workers and masters working outside were working across the wall. In the hot summer, standing next to a blast furnace with a temperature of several thousand degrees, although the temperature outside the furnace is far lower than that inside the furnace, it is indeed unbearable for people. But the workers and masters inside were drinking water, enjoying the cool breeze of the air conditioner, and sitting next to the machine. In contrast, "technology is the primary productive force" is indeed true. Thinking about it more carefully, the burden that falls on the shoulders of our contemporary college students, especially those of the School of Metallurgy and Ecological Engineering of the University of Science and Technology Beijing, is indeed not light. We must not live up to the glorious title of "School of Metallurgy", let alone live up to our "Beijing Iron and Steel Institute" is an alma mater that has cultivated steel heroes for more than 50 years and is known as the "Cradle of Steel".
Next we went to the main control room. Here, we interviewed a master worker from Chongqing who came to Baogang two years ago. According to him, after two years of training and practice, he has a good understanding of the operating model of Baotou Steelmaking Plant. A more comprehensive understanding made work much easier. Of course, this was due to the help and teachings of the old worker masters when we first entered the factory. The next day, July 20, we stepped into Baotou Steel again. On this day we The main ones I go to are the sintering workshop and the coal supply workshop. Here, Master Zhang led everyone from the coal storage workshop to the ball mill crushing workshop to the main control room. We were not very interested in other things, but we were very interested in the ball mill because we heard from the teacher that we were on holiday My mechanical drawing internship is to draw a ball mill, so everyone is very excited. The imaginary thing is right in front of us. We must take a good look at it so that we can have an impression when we go back to the internship, and it will be easier to draw. .
It rained all day on July 21st.
On the fourth day, July 22, the rain stopped. We walked into Baogang for the third time and began our visit and interview at Baotou Steelmaking Plant. At this time, the scorching sun may be raging in Beijing in July, but the heat in Baotou, thousands of miles away, is dissipating day by day. Our Baotou Steel Practice Group, a group of 5 people, came to Baotou Steel Steel Plant. After two days of visiting the iron plant, everyone was very tired. However, thinking about the hard-won internship opportunity of this visit, they all expressed their gratitude. Spirit. During these days, Master Wang, a master worker in the ironworks, first put down his work and accompanied us to visit the No. 4 blast furnace under the scorching sun. He patiently and carefully guided us. Since we are only sophomores and have limited professional knowledge, Therefore, there are always endless questions to ask. The master didn't show any annoyance at all and always answered all questions. Director Hao of the Baotou Steel Ironmaking Plant is an alumnus of our Beijing University of Science and Technology. During the few days we went there, Baotou Steel happened to be engaged in educational activities to maintain the advanced nature of Communist Party members. Director Hao, despite his busy schedule, was able to help us in detail to contact us about the visit to the Baotou Steelmaking Plant. It was not until later that we learned that thanks to their contact and communication, if we went there rashly, we would definitely not be able to complete our mission, even if we were not rejected. Through this experience, we at least understand that the atmosphere and environment on campus and in companies are so different. It also allows us young students who are about to enter the society to prepare a vivid social material in advance.
On July 23, 2005, we interviewed members of the Foreign Trade and Human Resources Department of Baotou Steel Group. 4. Discussing the development process of China’s industrialization
The realization of industrialization has always been the leader of *** The clear goal of the Chinese revolution.
After completing the task of restoring the national economy at the beginning of the founding of the People's Republic of China, the Communist Party of China and the Party Central Committee promptly put the historical task of industrialization on the central agenda and began to deploy and plan the blueprint for the country's industrialization construction. This was mainly reflected in the proposal of the "General Line for the Transitional Period" in 1952 and the formulation of the first "Five-Year Plan" for national construction in 1953.
The basic content of the party’s general line during the transitional period is: over a long period of time, gradually realize the country’s socialist industrialization and gradually realize the state’s social control of agriculture, handicrafts and capitalist industry and commerce. socialist transformation. (Referred to as "one modernization and three reforms".)
Its main body is to rapidly develop productive forces and realize socialist industrialization. 1. The first Five-Year Plan was fully and successfully realized. Starting from the inert situation at that time, the main task of the first "Five-Year Plan" (1953-1958) was to concentrate on the development of industry, especially heavy industry: metallurgy, fuel, and power. , machine manufacturing, chemical industry, etc.
It is planned that the total national investment in the five years will be 76.64 billion yuan (equivalent to more than 700 million taels of gold), of which 58.22 will be used for industrial infrastructure, to build a number of new industrial sectors with large scale and advanced technology, and to use modern Advanced technologies expand and transform existing industrial sectors. On the one hand, we must rationally utilize and reconstruct the existing industrial base in cities in Northeast China, Shanghai and other coastal areas; on the other hand, we must begin to build a number of new industrial bases in the interior, in order to greatly improve our country's industrial production capacity and gradually improve Unreasonable productivity layout.
While giving priority to the development of heavy industry, attention should be paid to overall consideration, balanced and coordinated development, and corresponding development of agriculture, transportation, light industry, post and telecommunications industry, commerce, culture and education. As Mao Zedong announced in the opening speech of the First National People's Congress in September 1954: "We are ready to build an economically and culturally backward country like ours into an industrialized country within a few five-year plans. A great country with a high degree of modern culture."
("Selected Works of the Communist Party of China", Volume 5, page 133.) Under the correct leadership and deployment of Chairman Mao and the Party Central Committee and the strong assistance of the Soviet Union, China A great victory in industrialization construction: the goals and tasks of the first five-year plan were successfully completed one year ahead of schedule.
During the first Five-Year Plan period, the country completed a total capital construction investment of 58.8 billion yuan, focusing on 156 large projects, and 694 industrial and mining construction projects above designated size were under construction. By the end of 1957, 428 were fully in production and 109 were partially in production.
Fixed assets increased by 49.2 billion yuan, 1.9 times that of 1952. Among them, there are many large projects and constructions, such as: Anshan Iron and Steel Company's three major projects - large-scale steel rolling mill, seamless steel pipe plant, and No. 7 iron-smelting furnace have started production; Ma'anshan Iron and Steel Company, Baotou Iron and Steel Company and Wuhan Iron and Steel Joint Enterprise are under construction; China's first automobile manufacturing plant (Changchun) was built and started producing "Jiefang" cars; China's first tractor manufacturing plant (Luoyang) was built; the first aircraft manufacturing plant was established and the first jet aircraft was successfully trial-produced; A machine tool manufacturing plant (Shenyang) was completed and put into operation; the first modern electronic tube factory (Beijing) was completed and put into operation; the first modern comprehensive factory for manufacturing radio components - North China Radio Equipment Factory started production; the first large-scale large-scale electronic tube factory in the northwest Power plant - Xi'an's second power plant was built; the first natural oil base - Yumen Oil Mine was built.
In addition, the Wuhan Yangtze River Bridge and Hengyang Xiangjiang Bridge were completed and opened to traffic, and the Qinghai-Tibet, Kangzang, and Xinjiang-Tibet highways were completed and opened to traffic, etc., all of which were created and completed during the first Five-Year Plan period. These constructions not only filled the gaps in some modern industries, but also carried out technological transformation of some old industries, significantly improving the foundation and production capacity of China's industry.
There are many important industrial products, such as generators, metallurgical and mining equipment, the latest metal cutting machine tools, automobiles, jet aircraft, etc. that could not be manufactured before, but now they can be produced. At the same time, since most projects and investments are invested in the mainland (for example, Wuhan alone has established large enterprises such as Wuhan Steel Plant, Wuhan Heavy Machine Tool Factory, Wuhan Boiler Factory, Wuchang Shipyard, and Wuhan Meat Combined Processing Plant), it is difficult to change the old The irrational layout of China's industry, which is too focused on the coast, plays a big role.
By 1957, the country's total industrial output value reached 70.4 billion yuan, an increase of 128.3% over 1952, and an average annual growth rate of 18%. The output of major industrial products: 5.35 million tons of steel, an increase of 296% from 1952, and 5.8 times the highest annual output before the founding of the People's Republic of China; coal output reached 130 million tons, an increase of 96% from 1952, and 2.1 times the highest annual output before the founding of the People's Republic of China; The power generation reached 19.34 billion kilowatt-hours, an increase of 166% from 1952, and 3.2 times the highest annual output before the founding of the People's Republic of China; the cement output reached 6.86 million tons, an increase of 140% from 1952, etc.
Most of the indicators were achieved ahead of schedule and exceeded. The achievements of the first five-year plan not only effectively proved the scientific and correctness of the party's general line for the transitional period and the planned economy, but also fully demonstrated the Communist Party of China's outstanding ability and ability in leading economic construction, especially the development of industry. Superb efficiency.
2. The Great Leap Forward Movement was indispensable. In the midst of the enthusiastic and comprehensive victory of the first five-year plan being completed ahead of schedule, Chairman Mao decided to further accelerate the pace of construction and development. To this end, a call for a "Great Leap Forward in Production" was issued.
In January 1958, he said: "China's economic backwardness and weak material foundation have made us still in a passive state, and we still feel mentally bound. In this regard, we have not yet been liberated. "We need to work hard."
"We need a technological revolution to catch up with and surpass Britain (referring to steel production) in fifteen years or more." ("Collected Works of the Communist Party", Volume 7, Page 350.)
"We must launch a production and construction revolution." Although there were many mistakes in the Great Leap Forward movement, its important status and great achievements cannot be denied in the history of China's industrial development.
For industrial construction, the Great Leap Forward achieved what people now call "supernormal" and "leapfrog development." There are many big projects, big constructions, and major scientific and technological achievements that were implemented and achieved during the Great Leap Forward.
For example, in the steel industry, not only Wuhan Iron and Steel Plant, the largest steelmaking plant in China at the time, was built, but also Handan Iron and Steel Plant, Jinan Iron and Steel Plant, Hangzhou Iron and Steel Plant, Guangzhou Iron and Steel Plant, Nanjing Iron and Steel Plant, Anyang Iron and Steel Plant. 5.

The plant's iron ore, coking coal and main raw fuels are all imported through Kaohsiung Dagang. 6. Thoughts after visiting Baotou Brewery
We were curious and excited, and couldn’t wait to rush in. The aunt in charge of the reception led us into the lobby. In order to let us know more about the brewery, we were first played a three-minute information video. From here I learned about the development history of the brewery: Baotou Snow Deer was built in 1981 and was acquired by Beijing Yanjing Group in 2000. In the past, the annual sales volume was 120 million tons, and now the annual sales volume is 600 million tons. I also learned that beer is made from mineral water from a 400-meter-deep well, barley and 80% hops imported from Australia.
After understanding the beer production process, we went to the production workshop to experience the beer production process with our own eyes. The first thing I went to was the "malt workshop", and then the saccharification workshop. There are gelatinizing pots and boiling pots inside, where the malt paste produced in the "malt workshop" is made into liquor. Finally, we came to the packaging workshop. It’s amazing to see those beer bottles without caps go into a machine like a boiler and come out with caps! Each machine can pack 10 bottles of beer per second and can produce 36,000 bottles of beer per hour.
The enthusiastic management staff also gave us a taste of non-alcoholic beer. I drank two cups of pineapple flavor, which was really delicious. After we visited the brewery, we also took a group photo in front of the brewery, leaving a wonderful memory.
We still walked on foot when we came back. Although the weather was cold, we gained knowledge and happiness. It was really a worthwhile trip! 7. Can anyone help me find out which steel plants are located in which city in China?
1. Anben Iron and Steel Base
Including Anshan Iron and Steel Company and Benxi Iron and Steel Company. It is located in the central industrial zone of Liaoning, leaning against the Qianshan Mountains to the east, the Taizi River, a tributary of the Liao River, to the north, Qianli plains on both sides, and the Bohai Bay to the south. The distance between the two steel companies in Anshan and Benxi is only 100 kilometers. The surrounding resources are rich, with proven iron ore reserves of nearly 10 billion tons, including more than 4 billion tons of industrial reserves, ranking first among major bases. The existing iron ore mining capacity is about 40 million tons, making it the largest iron ore base in the country. In 1990, the output of iron ore (raw ore) reached more than 38 million tons, accounting for more than 1/5 of the country's total iron ore output. Anshan Iron and Steel's main iron ore bases include: Dong'anshan, Yanyanshan, Qidashan, Dagushan and other iron ore mines, which are only 10 to 20 kilometers away from Anshan Iron and Steel and are distributed in an arc shape. Benxi Iron and Steel Co., Ltd. includes: Nanfen and Waitoushan, which are located in the south and north of Benxi Iron and Steel Co., Ltd., about 25 kilometers apart. Central Liaoning is also rich in coal resources, with coal mines such as Benxihu (Caitun) and Hongyang (Shennan) within 100 kilometers of the steel base. However, due to long-term mining, the coal in the area is insufficient to meet the needs of the steel industry.
After more than 40 years of reconstruction and expansion, Anben Steel Base is still the largest steel base in my country. In 1990, pig iron production was 10.1626 million tons, accounting for more than 16% of the country's total; steel production was 10.0816 million tons, accounting for more than 15% of the country's total; finished steel production was 6.3377 million tons, accounting for more than 12% of the country's total. Among them, Anshan Iron and Steel has a long history and a large scale.
