Although there is no hot plastic compression in the forming process, the residual stress still exists in the section. The cold plate will inevitably affect the overall and local buckling characteristics of the steel. The cold rolled section steel is generally open section without damage to the coating. It can be made into a variety of cross section forms. The production process of cold rolled steel plate and hot rolled steel plate is different.
Hot rolling is rolled at high temperature. Cold-rolled steel plate has better strength and cold-rolled steel plate has better ductility. The general thickness of cold rolling is relatively small, but that of hot rolling can be larger. Cold plates are used for cold bending spring sheets and other parts. They are of standard thickness. They look a little brighter than stainless steel when they are not rusted. Hot-rolled surfaces are rough.
There is no rule of cold rolling in shape, the wall thickness of cold rolled steel is smaller, and the cold plate is not thicker at the corner of the joint. At the same time, because the yield point is closer to the tensile strength, cold rolling and hot rolling are two different rolling technologies. Cold rolling is to roll the steel at room temperature, and the hardness of this kind of steel is large.
Above is the news that Anshan Shenlong Tengda Industry and Trade Co., Ltd. shares for you that cold rolling can make steel produce great plastic deformation. For more information, please contact us or pay attention to our website.
