Abstract

PURPOSE: To prevent a rolling material from the generation of camber in the whole length of it and partial chamber, by obtaining and setting the desired values respectively at the work side and drive side from the two equations of gauge meter to adjust the roll gaps by the AGC equations corresponding to the two equations.
CONSTITUTION: The desired roll gaps Swo, Sdo at the work side and drive side respectively are obtained by the two equationsI, II of gauge meter expressing the relations among plate thicknesses hw, hd at the exit of the work side and drive side respectively, reactive forces in rolling Fw, Fd, roll gaps Swo, Sdo, sheet width B, roll setting variables, and constants, then the roll gaps Swo, Sdo are set by above-mentioned method, respectively. During rolling, the respective roll gaps at the work side and drive side are adjusted based on the two AGC equations III, IV corresponding to the two equationsI, II.
