The working conditions of the rolls are the most complex in the roll section. Residual stress and thermal stress are generated during the preparation process of rolls before manufacture and use. When used, it is further subjected to various cyclic stresses, including bending, torsion, shear, contact stress and thermal stress. The distribution of these forces along the roll body is non-uniform and constantly changing, due not only to design factors, but also to the constant changes in roll wear, temperature and roll shape in use.
In addition, the conditions of the rolls are often abnormal. Improper cooling of rolls after use can also be damaged by thermal stress. Therefore, in addition to wear and tear of the roll, various local and surface damages such as cracks, fractures, peeling, and indentations often occur. A good roll should have a good match between its strength, wear resistance and various other performance indicators.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_btn title=”About LMM GROUP” link=”url:https%3A%2F%2Fwww.lmmgroupcn.com%2Fabout-lmm%2F|target:_blank”][vc_column_text css=”.vc_custom_1649296177864{margin-top: 50px !important;}”]friendship Link：
