Hot rolling is relative to cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the crystallization temperature. To put it simply, a piece of steel billet is heated and rolled several times, then trimmed and straightened into a steel plate. This is called hot rolling. It can significantly reduce energy consumption and reduce costs. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys, that is, break the coarse grains in the casting state, significantly heal cracks, reduce or eliminate casting defects, transform the as-cast structure into a deformed structure, and improve the processing performance of the alloy.

Hot-rolled coils use continuous casting slabs or blooming slabs as raw materials. They are heated by a walking heating furnace and descaled by high-pressure water before entering the rough rolling mill. The rough rolled material is cut into the head and tail and then enters the finishing mill. The computer is implemented. Controlled rolling, after final rolling, it undergoes laminar cooling (computer controlled cooling rate) and coiling machine to form straight coils.

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and shaping, and good weldability. Therefore, they are widely used in manufacturing industries such as construction, machinery, boilers, and pressure vessels.
Application scope:
(1) After annealing, it is processed into ordinary cold rolling;
(2) Galvanizing is processed by a galvanizing unit with a pre-annealing device;
(3) Panels that basically require no processing.
