What are the advantages of cold rolling and cold rolling strip steel?
Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
Cold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.
What to do with cold rolling is better than that of hot rolling, which is the main one because cold rolling is processed by hot rollingCold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
