Lime, an essential component in the steel industry

Especially worth highlighting is steel, a very versatile material that accounts for 80% of metal production and which is obtained by mixing Iron (Fe) and Carbon (C). The carbon content in steel does not exceed 1.5%, whilst foundry iron or pig-iron, which are also alloys of Fe-C, the carbon content is greater (between 2 – 4.5 %), which increases its hardness.

Steel Production

Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes ...
