Explanation

The smelting process of reducing iron from iron ore with solid or gaseous reducing agent. The early ironmaking method is called block ironmaking. China has produced liquid iron for casting since the Spring and Autumn Period. In the middle of the 14th century, the earliest blast furnace for smelting pig iron appeared. Since the 19th century, new technologies have been emerging, and blast furnace ironmaking ironmaking has become the most important ironmaking method. In addition, the new non blast furnace ironmaking ironmaking methods mainly include direct reduction and smelting reduction.
