Abstract

PURPOSE:To make both of increase bending and decrease bending possible by providing recesses to the stationary blocks mounted to a housing, fitting the collar parts of work roll journal boxes and pressing both rolls upward and downward. CONSTITUTION:Stationary blocks 2 having recesses 3, 4 in two upper and lower parts are mounted to a rolling mill housing 1. The respective collar parts of upper work roll journal boxes 10 and lower work roll journal boxes 14 are fitted respectively into the recesses 3, 4. The boxes 10 are moved upward and downward by the pistons 11, 12 of cylinders 5, 6 and the boxes 14 by the pistons 15, 16 of cylinders 7, 8. Thereby, increase bending or decrease bending is applied to the work rolls 9, 13. At this time, upper and lower intermediate rolls 17, 18 are properly moved in an axial line direction in compliance with the width of a metallic strip.
