Today, cold and hot strip mills around the globe are continuously looking for ways to increase their productivity, save energy, lower their overall costs and improve the final quality of their products. Using lubricant in cold rolling and controlling the roll-wear in hot rolling are some of the ways to achieve these goals.

Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm. The coefficient of friction is taken to be 0.2.

You face rolling problems in the finishing mill and an increased likelihood e.g. of tail end breaks. This is where camber-free rolling comes in.
