Abstract

PURPOSE:To stabilize the bending effect and to diversity shape control by giving a bending force to one or both of upper and lower intermediate rolls by cylinders installed on working and driving side slide blocks. CONSTITUTION:Cylinders 15, 16 installed on work and driving side slide blocks 13, 14 give roll neck bearing cases 9, 10, 11, 12 a load. Thus, a bending force is imparted to one or both of upper and lower intermediate rolls 4, 5. By this structure, transfer of a force to a work roll is directly performable and the shape control is diversified.
