Abstract

PURPOSE: To make camber small and to drastically reduce the trouble of rolling by calculating the required amount for changing leveling in the longitudinal direction of a rolled stock in a horizontal rolling mill as taking the variation coefficient of camber corresponding to rolling form into consideration.
CONSTITUTION: The measured results of camber and wedge of the rolled stock 1 before rolling (before entering a vertical rolling mill 2) are read from a camber meter 7 and wedge meter 6 corresponding to each position of the rolled stock 1 with an arithmetic and control part 9 for camber, the curvature of camber and wedge ratio are calculated and the variation coefficient of camber corresponding to the discriminated rolling form is read from a table and decided. And, the changing amount of wedge ratio is predetermined from the target curvature of camber and the required amount for changing leveling in the longitudinal direction of the rolled stock 1 in the horizontal rolling mill 3 is calculated. When the position of the rolled stock 1 is reached to the horizontal rolling mill 3, it is output to a drawing down position controller 5 and the camber of the rolled stock 1 is controlled.
