Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, to unroll and roll up coils of metal; Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by

Finished strip thickness ranges from 1.0 to 25.4 mm for coil box hot strip mills. In the 1980s, the compact strip production (CSP) type of hot strip mill was developed by SMS consisting of an electric arc furnace and a thin slab caster which produced a slab thickness of 50 mm and a direct coupled hot strip mill for rolling the thin slab to finished coils. Since 1989 when the first commercial

After cooling, slab is rolled at the hot rolling mill, creating hot coils (thickness: 1.5–16 mm). Some are sold; others go to the hot finishing mill for complementary work and hot sheet transformation or the cold rolling mill to lower strip thickness to 0.18 mm. Cold rolled coils are also dedicated for the tinning, galvanizing, and prepainting lines.

Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.
