The trading unit of coking coal futures is 60 tons/lot, and the minimum change price of coking coal futures is 0.5 yuan/ton. Therefore, when an investor holds a coking coal futures contract and one ton changes 0.5 yuan, then 60 tons (one hand) changes 30 yuan (0.5*60), so coking coal futures fluctuate by one point in 30 yuan, where one point refers to the minimum change price. If there is a big change, it will cost one yuan. Specifically, you can contact the official customer service consultation of the futures company.
1, coking coal varieties are complete, but the distribution is uneven. Among them, gas coal and 1/3 coking coal account for a large proportion in the identified coking coal resources, while coking coal and fat coal are the main types of coking coal, but the proportion is small. Under the condition of air isolation, the bituminous coal is heated to 950- 1050℃, dried, pyrolyzed, melted, bonded, solidified and shrunk, and finally coke is made. This process is called high temperature coking (high temperature dry distillation).
2. Coking coal is mainly used for blast furnace ironmaking and smelting of nonferrous metals such as copper, lead, zinc, titanium, antimony and mercury, and plays the role of reducing agent, heating agent and material column skeleton. Using coking coal instead of charcoal in ironmaking blast furnace has laid the foundation for large-scale modern blast furnace, which is a major milestone in metallurgical history. In order to obtain better technical and economic indexes in blast furnace operation, coking coal (metallurgical coke) for smelting must have appropriate chemical and physical properties, including thermal properties during smelting. Coking coal is not only widely used in ironmaking and nonferrous metal smelting (metallurgical coke), but also used in casting, chemical industry, calcium carbide and ferroalloy, and its quality requirements are different. Such as casting coke, generally requires large particle size, low porosity, high fixed carbon and low sulfur content; Coke for chemical gasification does not require high strength, but requires good reactivity and high ash melting point; Coke for calcium carbide production requires increasing the fixed carbon content as much as possible.
