磨损造成断裂弯卷板材的直径越小,接触力与切向应力就越大.磨损导致辊子的

The <br>smaller the diameter of the broken rolled sheet caused by wear , the greater the contact force and tangential stress. The <br>wear causes excessive stress on the roller, which may cause fracture at any time. <br>If the winding is rolled one by one, the bending torque will be reduced, so that the tangential stress will be reduced, and the lower roll tends to be safe. <br>In this case, it is necessary to pay attention to the fact that the rolling process should be divided into several passes, so that the pressure does not exceed the critical value. <br>The rolled plate should eliminate hard spots and impurities to avoid scratches and scratches. <br>At the same time, improve the surface hardness of the roller.
