Hot rollingHot rolling is a metalworking process that occurs above the material's recrystallization temperature. After the grains are deformed during processing, they recrystallize to maintain an equiaxed microstructure and prevent metal work hardening. The starting material is usually bulk metal, s

Cold rolling occurs when the metal is below its recrystallization temperature (usually at room temperature), increasing strength by up to 20% through strain hardening. It also improves surface finish and holds tighter tolerances. Commonly used cold rolled products are plates, strips, rods, rods; the

In metalworking, rolling is a metal forming process in which a metal billet is passed through one or more pairs of rolls to reduce thickness, uniformize thickness, and/or impart desired mechanical properties. The concept is similar to rolling dough. Rolling is classified by the temperature at which

Roller mills are mills that use cylindrical rollers, either in pairs or against flat plates, to crush or grind various materials such as grains, ores, gravel, plastics, etc. Drum grain mills are an alternative to traditional grinding stone arrangements in mills. Roller mills for rock complement othe

In the process of hot rolling production line, the discharged steel billet heated from the heating furnace to the target temperature first passes through the high-pressure water descaling box to remove the scale, and then enters the roughing mill stand area.
