leaves the temper mill. As most temper rolling of coated sheet is done on a mill stand that is located in the coating line (although it can be done on a stand-alone mill), it is important that the sheet flatness not be adversely affected by the operation. Obtaining good sheet flatness is part of the operational control exercised during temper ...

A temper mill is a finishing equipment that processes steel strips in order to give them added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling steel strips through a cold reducing process or temper pass. This increases the density of the steel by reducing its overall thickness between ...
