Patent DE-2750756-A1 (DE)
Inventor: TROEBS GERHARD
IPC: B21B37/56
Filed: 1977-11-12
Abstract: In the control of the elongation in rerolling stands, where elongation is taken to mean the increase in the length of the rolled stock in relation to the length at entry and a change in the manipulated variable due to a change in the elongation is made by means of an automatically adaptable evaluation coefficient, this evaluation coefficient is formed continuously from the ratio of the value of the manipulated variable to the product of the elongation and a variable dependent on the strip thickness and plant-specific constants. In this way, it is possible to determine reliably and continuously, under all operating conditions, this coefficient which determines the quality of the rolled stock.
