Brief Introduction of Stainless Cold Rolling Mill
Stainless steel has a large deformation resistance, which is generally twice as high as that of ordinary carbon steel; due to the deformation of martensite during the cold working process, the work hardening rate is fast and requires greater rolling force and load. Stainless steel has poor thermal conductivity. For example, the thermal conductivity of 321 stainless steel is only 27% of carbon steel. Therefore, the rolling mill is required to have stronger cooling capacity, high dimensional accuracy and plate shape requirements, and high surface quality requirements.
Stainless Cold Rolling Mill
Stainless steel cold rolling must be highly efficient and high-precision. The most prominent requirements for cold rolling mills are:
(1) It can produce wide and thin strip steel products, and requires fewer rolling passes and short rolling time;
(2) The total reduction rate, especially the first reduction rate should be large, try to achieve a rolling pass without intermediate annealing;
(3) Ensure product dimensional accuracy, good shape, and surface quality;
