Method for controlling a tensile force transmitted in the rolling stock in a continuous rolling train with m stands, and the circuit arrangement for carrying out the method

摘要

The invention relates to a method for controlling a tensile force transmitted in the rolling stock (42) in a continuous rolling train with m stands, in which the relative speed of successive drives (8) in the rolling direction, each provided with a rotational-speed control device (6), is corrected with a view to maintaining a constant tensile force in the rolling stock (42), and also relates to a circuit arrangement for carrying out the method. According to the invention, the lever arm (a) of each stand (1, 2, 3) of the rolling train is calculated by means of a computer (36) with tension on the outlet side. The accuracy of control and operational reliability are thereby significantly improved. <IMAGE>
