Galvanized coil, in which a thin steel plate is immersed in a molten zinc bath so that a layer of zinc is attached to its surface. At present, it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in zinc bath to make galvanized steel plate; Alloy galvanized steel plate. This steel plate is also made by hot dip plating, but it is heated to about 500℃ immediately after it is taken out of the tank to form an alloy coating of zinc and iron. This galvanized coil has good adhesion and paint weldability.

Galvanized coils can be divided into the following categories:

A) Hot dip galvanized steel coil. Immerse the thin steel coil in molten zinc bath to make the surface of the thin steel coil adhere to a layer of zinc. At present, it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in zinc bath to make galvanized steel coil;

B) alloy galvanized steel coil. This kind of steel coil is also made by hot dip method, but it is heated to about 500℃ immediately after it is taken out of the tank, forming an alloy coating of zinc and iron. This galvanized coil has good adhesion and weldability of paint;

C) galvanized steel coil. Galvanized steel coil produced by electroplating method has good processability. However, the coating is thin and the corrosion resistance is not as good as that of hot dip galvanized coil;

D) Single-sided galvanized and double-sided differential galvanized steel coils. Single-sided galvanized steel coil, that is, a product that is galvanized only on one side. It has better adaptability than double-sided galvanized coil in welding, painting, antirust treatment and processing. In order to overcome the disadvantage of not coating zinc on one side, there is another kind of galvanized coil with thin zinc on the other side, that is, double-sided differential galvanized coil;

E) Alloy and composite galvanized steel coils. It is a steel coil made of zinc and other metals (such as lead and zinc), and even has a cladding. This kind of steel coil not only has excellent antirust performance, but also has good painting performance.

It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in zinc bath to make galvanized steel plate; Alloy galvanized steel plate.

This steel plate is also made by hot dip plating, but it is heated to about 500℃ immediately after it is taken out of the tank to form an alloy coating of zinc and iron. This galvanized coil has good adhesion and paint weldability.

What are the materials of galvanized coil?

Galvanized sheet refers to a steel plate with a layer of zinc on its surface. Galvanizing is a common economical and effective anti-corrosion method. About half of the world's zinc production is used in this process. 1. The definition of galvanized steel sheet is to prevent the surface of steel sheet from being corroded and prolong its service life. Galvanized steel sheet is called galvanized steel sheet. 2. Classification and use According to the production and processing methods, it can be divided into the following categories: ① Hot-dip galvanized steel plate. Immerse the steel plate in molten zinc bath to make a layer of zinc adhere to the surface of the steel plate. At present, it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in zinc bath to make galvanized steel plate; ② Alloy galvanized steel plate.

How to treat galvanized coil futures

Galvanized coil is a kind of thin steel plate, which is immersed in molten zinc bath to attach a layer of zinc to its surface. At present, the price of galvanized sheet in the domestic steel market is temporarily stable, with no big fluctuation.

The price of galvanized sheet basically changes with the change of galvanized sheet price. As a derivative product of galvanized sheet, the attention is not high. Galvanized sheet is widely used in foreign buildings, although it is not very common in China.

I don't know much about galvanized coils. Let's learn about the strength and hardness of galvanized coils, which are soft and hard.

Galvanizing is divided into cold rolling and hot rolling, which is what you call soft and hard.

hot rolling

Hot rolling, using slab as raw material, after heating, it is made into strip steel by roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature by laminar flow and coiled into a steel strip coil by a coiler. The cooled steel strip coil is processed into steel plate, flat coil and longitudinal shear steel strip products through different finishing lines according to the different needs of users. Simply put, a billet is heated and rolled several times, and then trimmed and corrected into a steel plate. This is called hot rolling.

cold rolling

Cold rolling: the hot rolled steel coil is used as raw material, and then the oxide scale is removed by pickling, and the finished product is hard rolled steel coil. Because of the cold work hardening caused by continuous cold deformation, the strength and hardness of hard rolled coil increase, and the toughness and plasticity index decrease, so the stamping performance will deteriorate and it can only be used for simple deformed parts. Because all hot dip galvanizing units are equipped with annealing units, hot rolled steel coils can be used as raw materials for hot dip galvanizing units. The weight of hard rolled coil is generally 6~ 13.5 tons, and the hot rolled pickling coil is continuously rolled at room temperature. The inner diameter is 6 10 mm.

Product features: because it has not been annealed, it has high hardness and poor machinability. It can only be used for simple directional bending less than 90 degrees.

Simply put, cold rolling is processed and rolled on the basis of hot rolled coil. Generally speaking, it is a hot rolling-pickling-cold rolling process.

Cold rolling is a hot rolled sheet at room temperature. Although rolling also increases the temperature of the plate during processing, it is still called cold rolling. Due to continuous cold deformation during hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties, and those that are not annealed are called hard rolls. Hard coil plate is generally used to make products that do not need to be bent or stretched, and the thickness is lucky to be bent on two sides or four sides below 1.0.

What is a galvanized coil? Recommended by galvanized coil manufacturer

With the development of our science and technology, our life is becoming more and more convenient, and to a certain extent, our industrial manufacturing is also more convenient. At present, the most widely used metal is steel, but it cannot be used in all fields because of its performance limitations. Bian Xiao introduces galvanized steel plates and their manufacturers.

First of all, let's briefly understand what galvanized coil is.

Galvanized coil is also one of our new materials. Its main raw material is zinc alloy, and its production process is continuous zinc plating.

There are many kinds and models of galvanized coils, and we mainly classify them according to their performance. We usually use numbers to express it. Galvanized coil, which is still very popular in the world today, has the advantages of good adhesion and weldability. Similarly, nothing in the world is without shortcomings, and so is galvanized coil. Its disadvantages are exposed steel, inclusions, mechanical damage, etc., and this situation is mainly due to the role of surface oxidation.

After we have a simple understanding of galvanized coil, let's take a look at the relevant introductions of three galvanized coil manufacturers.

The first company: Shanghai Island Steel Shear Co., Ltd., is a comprehensive enterprise integrating processing and distribution. Moreover, the quality of galvanized coils under the company has passed the national standards, and the second mold is also very complete. I believe it will give you satisfactory service.
