From ore to steel – ArcelorMittal

ArcelorMittal has a diversified fleet of production facilities to make steel, both basic oxygen furnaces and electric arc furnaces. In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel. About 12% of our steel is made from recycled steel.

The History of Steel

Jun 25, 2019 · One of the earliest forms of steel, blister steel, began production in Germany and England in the 17th century and was produced by increasing the carbon content in molten pig iron using a process known as cementation. In this process, bars of wrought iron were layered with powdered charcoal in stone boxes and heated.
