Abstract

PURPOSE: To prevent the offsetting of the center of the material to be rolled from the center of the ring rolling mill, to restrain the slip of the roll so as not to cause the deflection, by setting the number of revolutions of the axial roll so as to make the average circumferential speed of the material to be rolled on the king roll side to coincide with the average circumferential speed of the material to be rolled on the axial roll side.
CONSTITUTION: Information from the optical breadth meters F1, F2, the potentiometers S1, S2, the tracer roll T and the tachodynamo P1 is inputted to the axial roll's number of revolutions setter Q, to which information about the king roll's diameter DK is previously inputted; depending on above information, the set value NAX for the number of revolutions of axial rolls AX, AX, is operated and is inputted to the comparison circuits C1, C2. The actual number of revolutions of the axial rolls AX, AX, is inputted to the comparison circuits C1, C2, which then compare these actual values with the set value NAX for the number of revolutions, being inputted from the setter Q, and controls the driving motors E1, E2, of the axial rolls AX, AX, so as to make these values to coincide with each other.
