  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To make simple and exact the FTC control of the rolling mill, by stopping action of the FTC unit according to the detecting signal produced when the tail end of rolled material goes out of the edger stand.
CONSTITUTION: The material position detector 24 detects the timing at which the tail end of rolled material 23 goes out of the mill stand 1 to be the edger stand; at this point, the action of FTC unit 19 for controlling the variation of torque generated by the DC motor 5 for driving the rolling mill of next stand 2, as the variation of the interstand tension between the stands 2, 3; hereby, FTC unit 19 holds the correction value ΔN1 for the speed formerly obtained by the unit 19. Under the condition that the material 23 is being rolled across the stand 1 to the stand 3, the correction value ΔN1 for the speed operated by FTC unit 19 is inputted as it is to the adder 14 through the holding unit 25; and the speed of the motor 5 is controlled through the speed controller 11, and hereby, the interstand tension between the stands 2, 3, is controlled.
