Causes of work roll damage in industry


We should have heard of the rolls, but in recent years, the rolls in the factory have often suffered a little damage, so are the rolls used in the industry really so weak?

In fact, the most complex of all the components of the roll is the rolling mill. There will be a preparation process before the roll is used. During the preparation process, the roll will generate some unnecessary stress, including thermal stress and residual stress. As the roll starts to work, it will be affected by various stresses. These forces It is uneven on the body of the roll, and it is constantly changing. After the roll is not properly cooled, these stresses will cause different degrees of damage to the roll itself, so the surface of the roll will be damaged. The body may even break.

Therefore, if you want a roll to work better, you must use it correctly, and try to choose some rolls with good quality. This will not only save us money, but also the service life of the roll itself will be very long.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_btn title=”About LMM GROUP” link=”|target:_blank”][vc_column_text css=”.vc_custom_1649296177864{margin-top: 50px !important;}”]friendship Link:
