A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.

BOFs, EAFs. Molten steel is made in one of two ways: in a basic oxygen furnace (BOF) in an integrated mill, or charged in an electric arc furnace (EAF) in a minimill. (In this context, "basic" refers to the pH content of the slag and the refractories that line both types of furnace.) Integrated mills have a twostep approach.

Steel mills ' primary feature is rolling steel, a procedure that reduces the cross section of the metal while increasing its length proportionately. Generally, rolling mills are graded according to the content they produce. Direct drive is chosen if the mill's speed allows. In general, direct drive (directconnected motor) is not desirable for speeds less than 150 rpm and outputs less than 750 kW.
