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 .

The use of this process represented 54.9 % of the total steel production in the United States, down from 56.2 % in 1997. In the 1990's companies running integrated mills have focused more upon specialty steels, particularly hot dipped galvanized, to ensure that automobile manufacturers continue using steel as the material of choice.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel production. Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace.

When steel scrap is processed in an electric arc furnace (EAF), about 15–23 kg of dust are formed per tonne of steel, which, referring to steel production for 2012, translates to between 6.7 and 10.3 million tpa of EAF dust being produced. Table 9.2 provides a summary of the composition of EAF dust as well as other zinc- and lead-containing residues.
