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.
Jun 19, 2017 Cascade control uses the reduction concept (R-Factor) to calculate the mill cascade speed reference. This parameter, directly related to rolling fundamentals, simplifies the setup and operator control. During production the loop and tension control automatically adjust the R- Factor, ensuring minimum material stress between the stands.

Aug 16, 2001 A higher production rate or running heavier metals through the mill requires more frequent checks. Shafts should be checked for OD, looseness, bending, and parallelism. Shoulder alignment should be checked, and the integrity of the entry table, drive stands, side roll boxes, weld box, and Turk's head units should be ensured.

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 CSP plant was started up at Nucor in Crawfordsville, IN, there have been many CSP hot …
