After iron ore and coking coal are put in a blast furnace with about 100m in height, hot air of 1200℃ is blown in. The heat generated in the way of burning coking coal melts iron ore.
CO generated in the course of burning coking coal has reduction reaction with iron ore. In such a way, molten steel is manufactured.
In other words, coking coal not only serves as the heat source of melting iron ore, but separates oxygen and molten steel in oxidized steel.
It takes 5 to 6 hours to change the iron ore put in the blast furnace to molten steel. At t his time, the temperature of the molten iron goes up to 1500℃.
The molten iron contains not only steel components, but impurities like carbon or sulfur. It is called pig iron.
