How is iron ore processed into steel

Nov 26, 2020

How to make steel from iron ore: The raw materials of blast furnace ironmaking are iron ore and coke, but there will be a further processing flow before iron ore and coke enter the blast furnace, namely iron ore sintering and coking coal. After the raw materials are solved, they will be put into the blast furnace, and these raw materials will
