[0037] See figure 1 , figure 1 A flow chart of a method for controlling the width of a hot-rolled widening billet provided by the first embodiment of the present invention is shown. The steps that described method comprises are as follows:
[0038] Step S10: On the width-adjusting billet before entering the side press, determine a plurality of head measurement points and a plurality of tail measurement points.
[0039] In step S10 , since the side press needs to be controlled, it is necessary to measure the width of the widening billet before entering the side press. Multiple head measurement points should be close to the head position of the widening blank, and multiple tail measurement points should be close to the tail position of the widening blank. In order to avoid the influence of mutual interference of short-stroke control, the head and tail of the widening billet can be removed before determining the measurement point, that is, the specific execution of step S10 is...
