FIELD: process engineering.
SUBSTANCE: proposed method comprises refacing roller pass groove. After refacing, roller are mounted into stand. Note here that pass size is increased by amount of wear. Note here that rollers with variable-section pass groove are turned by amount compensating pass wear size on varying positions of rollers. Rollers are turned by displacing tooth-rack drive racks toward rolling start. Displacement of said racks is effected in lengthwise direction in compliance with stand design to allow aligning top and bottom roller pass grooves and make pass groove sections aligned with turn angle of crank that defines stand position.
EFFECT: simplified design, higher reliability, longer life, lower costs.
