Due to changes in billet quality during production, the total length of the rolled pieces is different, as well as the head and tail errors during the rolling process and the tolerance of the unit mass of the rolled products. As a result, the lengths of the rolled pieces entering the cooling bed cannot all be the same, so they are divided into different lengths.
In the last section of segment shearing, short-length material will enter the cooling bed. If it is not removed before the cooling bed, it will become the source of any automatic claser cutting stainless steel accident.
Generally speaking, most of the rolled parts are first sheared according to the length of the cooling bed, and then the remaining parts are sheared into cooling lengths. At the same time, the action cycle of the cooling bed lifting skirt is adjusted, so that the shearing The program avoids any problems caused by irregular lengths of short rulers.
