Coking process flow

The technological process of coking is the process of producing coke, coke oven gas and other coking chemical products through thermal decomposition and coking. Metallurgical coke has high carbon content, high porosity and high strength (especially high temperature strength). It is an important fuel and reducing agent for blast furnace ironmaking, and also a proppant and loosening agent for the whole blast furnace burden column.

Coke oven gas is a by-product of coking with high calorific value. It is an excellent gas fuel for open hearth and heating furnace, and also an important energy component of iron and steel complex. Coking chemical products are important chemical raw materials. Therefore, coking production is an important link in modern iron and steel industry.

Extended data

The production of coking originated from the dry distillation of piles of coal. 1709 After the successful experiment of replacing charcoal with coke in British blast furnaces, by the end of 18, most blast furnaces in Europe had used coke to make iron, which promoted the large-scale development of coke production. However, due to the limitation of technical level, the production of coke is still scattered near coal mines, and it is carried out by dry distillation in piles, which is the initial state of coking industrial drums.

/kloc-in the middle of the 9th century, the annual output of pig iron in the world was close to100000 tons, mainly in Europe. The annual demand for coke exceeds 20 million tons. At the same time, ammonia, benzene and coal tar, as by-products of coking, have become indispensable raw materials for emerging chemical and pharmaceutical industries.
