the decomposition of the various processes of the iron and steel complex
The production of an iron and steel complex consists of a number of different processes. In this paper, it is divided into iron making, hot metal pretreatment, steel making, off-furnace refining, continuous casting, steel rolling, finishing and other parts, and the focus of low-cost production of clean steel lies in the development and application of iron making, hot metal pretreatment, steel making, off-furnace refining, continuous casting and other processes. This is also the focus of this paper.
(1) Ironmaking
The cost of iron making and the quality of hot metal have a great impact on the efficient and low-cost production of clean steel, especially in the current situation of the price of iron making raw materials is more important. Fully understand the price, composition and characteristics of all kinds of mineral powder and solvent, improve and stabilize the grade of raw materials; To master the properties of coke and injection coal, and strive to reduce the coke ratio; Ensuring high and stable hot air temperature and so on are necessary measures to maintain the stability of the blast furnace, along the line, high yield, in order to increase the cost of high-quality hot metal for steelmaking.
