APPARATUS FOR LEVELING TOP ROLL OF ROLLING MILL WORKING STAND Russian patent published in 1997 - IPC

FIELD: plastic working of metals, in particular, rolling equipment. SUBSTANCE: apparatus has cross-piece movable by drive, choke hanging tie-rods and top roll loop hanging tie-rods positioned in pairs on cross-piece. Apparatus is further provided with double-armed levers, with number of levers corresponding to the number of pairs of tie-rods. Levers are pivotally secured on cross-piece. Each lever is coupled with its one end to choke hanging tie-rod and with its other end to top roll loop hanging tie-rod. Levers allow value of biasing force applied by choke inserts to roll neck to be unaltered during operation. Lever arm have length selected in proportion reverse with respect to applied forces. Tie-rod for hanging top roll loops is connected with related arm of double-armed lever through intermediate tie-rod to simplify roll changing process. EFFECT: increased efficiency and simplified method. 2 cl, 1 dwg
