METHOD FOR ROLLING-DOWN WIDTH OF METALLIC SHEET

摘要

PURPOSE:To improve responsiveness in camber control, to miniaturize the device and to make it light in weight. CONSTITUTION:A pair of width rolling-down dies 1 arranged on both sides of a pass line L are moved back and forth in the width direction to roll down a metallic sheet S and a load difference in the plate width direction given to a pair of vertical rolls 19 which come in contact respectively with both sides of the metallic sheet S is detected at the neighborhood on the outlet side of the width rolling-down dies 1. At least one of the width rolling-down dies 1 is rotated to correct the camber so that the load difference is reduced to zero.
