Integration of outdoor cabinet of steel hot-rolled and cold-rolled steel, for both steel and you know how much?
Today by the integration of outdoor cabinet factory in shenzhen hui technology co. , LTD. , under the belt you know the primary difference between hot rolled steel and cold rolled steel.
;
1, the appearance and surface quality:
;
because of cold plate is, resulting from the hot plate in cold rolling process and cold rolling at the same time also will make some surface finishing so cold plate on the surface quality ( Such as surface roughness, etc. ) Better on specific heat plate, so if the product after the sequence on the quality of paint coating, such as there are higher requirements, generally choose the cold plate, hot plate, pickling board and other pickling plate, pickling board surface as the pickling too so into normal metal color, but remained in the high cold plate, cold rolled so surface without pickling plate surface oxide layer, usually hair black, or ferroferric oxide layer. Popular speaking, is the fire roasted, and if the environment is not good usually bring some rust.
;
2, performance:;
;
in general, hot plate and pipes in the engineering mechanical properties are no more thought, although there are certain work hardening heat pipes in the process of cold rolling, ( But do not rule out strict in mechanical properties, that is need to differentiate between) The heat plate, cold plate usually slightly high yield strength, surface hardness is higher, what specific needs to see the degree of cold plate annealing. But no matter how annealing cold plate strength is high specific heat plate.
;
3, formability;
;
due to hot and cold plate performance basic difference is not too much, so the influence factors of forming performance depends on the difference between surface quality, due to the better surface quality is studied experimentally to, so generally steel plate with the same material, cold plate heat plate forming effect is better.
