Description
technical field [0001] The invention relates to a strip-threading protection device for a flat roll, which is applied to a strip steel cold rolling unit to protect the flat roll and prevent the strip head from damaging the flat roll during the strip threading process. Background technique [0002] In cold-rolled strip production, shape rolls are used to detect and participate in controlling the shape of the strip. Whether the shape roll can work normally is directly related to the quality of the final product of the cold rolling mill. In general, when the strip is threaded, the steel strip directly contacts the flat rollers. Because the strip head is in bad shape or has burrs, it is easy to cause damage to the flat rollers and affect the service life of the flat rollers. Contents of the invention [0003] The object of the present invention is to provide a belt-threading protection device for flat rollers with simple structure and prolonging the service life of the flat r...
