Abstract (en)
A four-high rolling mill has back-up rolls (16, 17) which have effective barrel lengths substantially shorter than those of the work rolls (14, 15) so that the ends of the work rolls are unsupported, with the result that the work roll bending equipment (25) acting between the ends of the work rolls become more effective. When the width of the material (30) being rolled is greater than the effective length of the back-up rolls (16, 17), the rolling load is transferred to the housing (12, 13), in part through the back-up rolls (16, 17) and in part through piston and cylinder assemblies (26) between the work roll chocks (18, 20) an the back-up roll chocks (21, 22).
