Sunflag Steel 5 Steps of Steel Manufacturing

The BOF process uses 30% of recycled steel, while EAF uses up to 90-100%. This is a far more sustainable option instead of mining more iron ore as a fresh ingredient in the steelmaking process. There is also an alternate steelmaking process called HIsarna ironmaking. In HIsarna, iron ore is processed immediately into hot metal.

Steel Manufacturing Process AIST

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel
