Abstract

PURPOSE:To sufficiently correct cambers by measuring cambers of a roughly rolled stock on the outlet side of a rough rolling mill line, correcting cambers based on the measured values, and finishing rolling after the correction for a not rolling line of a rough and a finishing rolling mill line. CONSTITUTION:A hot rolling line consists of a rough rolling mill line 2 and a finishing rolling mill line 3. A camber meter 4 and a straightener 5a are installed on the outlet side of the mill line 2 and a straightener 5b is installed on the inlet side of the finishing line 3. A roughly rolled stock pauses on the outlet side of the line 2 and cambers at the front and rear edges of the stock are measured by the camber meter 4. A computing element 6 for camber amount calculates a camber amount based on the measured values and the element 6 sends the camber amount to a controller 7, which sends control signals to the straighteners 5a and 5b and the cambers at the front and rear edges of the roughly rolled stock are corrected.
