Abstract

994,523. Rolling. F. MOELLER, and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER & NEUMANN G.m.b.H.]. Oct. 25, 1963 [Oct. 25, 1962], No. 40399/62. Heading B3M. In a control device for rolling strip in a reversing roll frame 1, the incoming and outgoing strip thickness, the rolling pressure, and the strip width are measured by gauges 3, 4, 2 and 10 and the pass reduction for the next pass is derived, the device comprising computing appliances 12 and 14 in which during a control pass the specific deformation resistance of the strip is computed from the pass reduction, strip thickness, and rolling pressure, and in which, in combination with further computing appliances 15, 18, 21, 29 and 34 which correct the deformation resistance dependently on the time period between passes and the intended changes in strip thickness and rolling speed, obtain a pass reduction for the next pass after the introduction of a value of rolling pressure for the next pass according to a preselected rolling plan. During rolling the strip temperature and strip thickness are computed and indicated at 22 and 34a respectively. The strip speed is measured by a device 11, and the actual screwdown is made at 37 under the control of an appliance 36 in which a correction factor due to the falling roll pressure may be obtained. Further apparatus is described in which reduction figures are obtained by working backwards from a final desired strip thickness.
