Abstract
An improved roll shifting system for rolling mills comprising a pair of work rolls positioned on each side of the rolling plane, a pair of upright frame posts defining an opening in which chock guides are mounted facing the opening and chocks on each axial end of each roll. The chock guides have upper and lower leg portions extending outwardly from the frame posts upon which box slides are mounted. Hydraulic pistons and cylinders connected between the distal end of the box slides and the distal end of each leg move the box slides, thus moving the chocks carrying the work rolls.
