Fundamentals of Roll Cooling and Control of Flatness at ...
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product....
How exactly does a rolling mill work?
Jan 28, 2009· Rolling mills are rated first by maximum strip width and then by roll separtion force. Commercial strip mills generally have a RSF of several thousand tons. Small mills in general, and certainly hobbist mills, are static. The roll gap is set and then the strip is fed into the mill....
