Abstract

PURPOSE:To highly accurately control the width of strips, by measuring the temperature of materials to be rolled during the course of width control and by inputting the measured value as one of the parameters to be used when the vertical opening is found. CONSTITUTION:A width meter 1 which detects the width of a material 3 to be rolled, a thermometer 2 which measures the temperature of the material 3, and a pulse generator 6 which detects the length of the material 3 are installed to the inlet side of a vertical roll 8. The length of the material 3 is obtained by counting the pulse obtained from the pulse generator 6. When values of the width W and the temperature T of the material 3 are inputted into a width controlling device 13, the width controlling device 13 operates the width value DELTAW from the values now inputted and previously inputted thickness of the strip H at the inlet side of the vertical roll 8, the total expansion amount DELTAE, and the thickness of the strip (h) at the outlet side when the strip is horizontally rolled by a horizontal roll 12 after the vertical roll 8, and according to the formula. The C1, C2, C3, C6, C7, and C8 in the expression are specific coefficients. Control of width rolling of the vertical roll 8 is performed by driving a motor for driving the opening of the vertical roll 8 based on the width value DELTAW thus obtained.
