HOT ROLLED STAINLESS STEEL SHEET

By definition, ingot or billet is difficult to deform and process at room temperature. Generally, it is heated to 1100 ~ 1250℃ for rolling. This rolling process is called hot rolling. The high temperature of the hot rolled plate makes the deformation resistance small and the deformation quantity large. Taking rolling of steel plate as an example, the general thickness of continuous casting billet is about 230mm, and after rough rolling and finishing rolling, the final thickness is 1~20mm. At the same time, because of the steel plate width ratio is small, size accuracy requirements are relatively low, not easy to appear plate shape problem, mainly to control the crown. The microstructure and mechanical properties of the strip are controlled by controlling the rolling temperature, the final rolling temperature and the crimping temperature.

COLD ROLLED STAINLESS STEEL SHEET

Cold rolling is the further thinning of steel plates at room temperature below the recrystallization temperature to the target thickness of steel plates. Compared with hot rolled steel sheet, cold rolled steel sheet thickness is more accurate, and the surface is smooth and beautiful. Cold - rolled sheet has no heating process before rolling. However, because the thickness of the strip is small, it is easy to appear the plate shape problem. Moreover, after cold rolling, it is the finished product. Therefore, in order to control the dimension accuracy and surface quality of the strip, many complicated processes are adopted. The cold rolling production line is long, the equipment is many, the craft is complex.

Manufacture belt use is very wide, such as automotive electrical products, such as rolling stock aviation precision instrument canned food cold rolled steel sheet is short for ordinary carbon structural steel manufacture, also known as manufacture, commonly known as the cold plate, are sometimes mistakenly written lengzha board cold plate is made up of ordinary carbon structural steel hot-rolled steel belt, after further made from cold rolled steel plate thickness is less than 4 mmAs a result of rolling at room temperature, do not produce iron oxide, so, cold plate surface quality, high dimensional accuracy, coupled with annealing treatment, its mechanical properties and technological performance are better than hot rolled thin steel plate, in many fields, especially home appliances manufacturing field, has gradually replaced the hot rolled thin steel plate
