Abstract
PURPOSE: To restrict the generation of deformation at the end of rolled maerial for the purpose of improving the yield, by controlling the rotational speed of the rolling roll so as to give the compression force uncausative the buckling stress to the rolled material in the stand.
CONSTITUTION: The memory unit 9 stores the constant to be specified correspondingly to the rolling condition like as the electric current values of motors 3, 4, of upper and lower work rolls 1, 2, of the N-th and the (N+1)th stands, the rolling loads of the rolls 1, 2, detected by the load cells 10, 11, etc. Then, the operator 12 operates the specified numerical formula model by substituting the data given by the memory unit 9. Next, the operator 12 gives the set value to the speed setters 13, 14, in order to give the rolled mateial 15 the specified compression force uncausative the buckling stress in the rolled material 15 when the material 15 is fed to the N-th and the (N+1)th stands; hereby,the rotational speeds of the N-th and the (N+1)th stands are controlled.
