The ironmaking process is essentially the process of reducing iron from its natural state - ore and other iron-containing compounds. The main methods of ironmaking include blast furnace method, direct reduction method, molten reduction method, etc. The principle is that the ore is atomized in a specific atmosphere (reducing substances carbon monoxide, hydrogen, carbon; suitable temperature, etc.) to obtain reduced pig iron. Except for a small part of pig iron used for casting, most of it is used as raw material for steelmaking.
Blast furnace ironmaking is the main method of ironmaking now and an important link in steel production. This method is developed and improved from ancient vertical furnace ironmaking. Although many new ironmaking methods have been studied and developed in various countries around the world, due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor productivity and low energy consumption, the iron produced by this method can account for more than 95% of the world's total iron production.
