Roughing Mill - an overview | ScienceDirect Topics

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.

Steel Rolling Mill Machine: Hot Rolling Roll

Semi-steel roll is most suitable for heavy work billet mill, large section mill, medium mill, universal section mill, hot continuous roughing mill, and hot continuous finishing mill (front section). Because its hardness is lower than that of chilled cast iron roll, and it is easy to expand when heated, it is generally not used in the finishing mill and finished product stand.
