For example, after pickling, some steel grades are trimmed by a circle shear, and after the circle shear is sheared, burrs or sharp points are often formed on the edges of the strip. The sharp peaks or burrs can cause abnormal abrasion to the edge parts of the working roll, the middle part, the guide, the deviation correction and the like, so that the roll replacement is frequent, the service cycle of the roll is short, and the production cost is increased; and the transfer printing quality problem of the surface of the strip steel can be caused by the abnormal appearance of the roller surface caused by uneven wear of the edge part of the roller surface, so that the width printing problem of the surface of the strip steel is caused.
In the actual production, the burr is fundamentally prevented from being generated, and the difficulty is quite high. At present, the control is carried out by methods such as adjusting parameters of a circle shear, replacing a shear blade and the like, but the effect is limited; another commonly used method for controlling sharp peaks or burrs is to add equipment for grinding the edges of the strip steel.
