Steel mill - Wikipedia. A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also describe plants where steel semi-finished casting products (blooms, ingots, slabs, billets) are made, from molten pig iron or from scrap.

How Steel Is Made. 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 ...

Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required.

Blast furnace-basic oxygen furnace uses iron ore as its base raw material that accounts over just 50% of BOF steel costs, and electric arc furnace uses scrap as its base that represents around 75% of EAF steel cost. The Basic Oxygen Steelmaking process differs from the EAF is that BOF is self-sufficient in energy.

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
