Abstract
PURPOSE: To approximately equalize the elongations on both sides, by separately performing the control for the rolling reduction on the work side and the drive side, at carrying out the rolling work under the condition that the center of breadth of the rolled material is shifted from the mill center to the work side or the drive side.
CONSTITUTION: The roll gap at the center of the breadth of the rolled material is held at a constant value, by controlling the rolling reduction on the work side and the drive side. For this purpose, either one of the formula I or its approximate formula II is to be satisfied in performing the control; in the formulas I, II, ASW, ASD, are for the rolling reductions respectively on the work side and on the drive side (both are made plus in the direction to reduce the roll gap), Δx is for the offset of the rolled material's breadth center from the mill center (the offset toward the work side is made plus), l is for the distance between the fulcrums of the rolling reductions on the work side and the drive side, and Dt is for the vertical distance from the fulcrum of the rolling reduction to the roll gap.
