the Flex Mill. It consists of a thin-slab caster, a tunnel furnace, and a rolling mill with six stands and one downcoiler. Caster The cast slab thicknesses range from 55 to 85 mm (2.17 to 3.35 inches) and allow the mill to "flex" between heavy and light gauges, as well as meet reduction ratios required in producing demanding steel grades.

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating
Cold Compact Mill (CCM) Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil. Unique Features
cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 50-75 mm. 2. First intermediate roll (tapered), diameter between 90-105 mm. 3. Inner second intermediate roll (CVC roll), diameter between 177-182 mm.
