A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten. It has long been recognized that some, if not most, of the variations in thickness of strip produced by a coldreduction mill have their origin in the hot rolling process. For example, it has ...

Cold Rolled steel has an improved surface finish and tighter tolerances compared to hot rolled steel. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for Shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods. Cold Rolled Steel can be purchased online and at any ...
Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls have got deflected by high rolling forces. Elastic deformation of the mill takes place. If stiffer rolls are used, namely roll material of high stiffness or elastic constant, then mill spring can be avoided. Normally elastic constant for mills may range from 1 to 4 GN/m. Roll elastic ...
