Why Does the Rolling Opportunity Fail to Roll?

Why does the rolling opportunity fail to roll?

In fact, the leakage of the rolling mill is quite common in the production process, which will have a serious impact on the normal rolling industry of enterprises. So, do you have a serious understanding of the factors of this kind of failure and the relevant solutions?


The basic conditions and factors of rolling mill leakage are the same. When the rolling mill is running, the rolled piece will certainly have a certain impact on the roll, which will lead to vibration and spring. In such cases, the rolled piece will pass through the mill directly and avoid contact with the rolls, which will lead to the leakage of rolling.


If this situation is persistent, then it is necessary to stop the rolling mill for maintenance and adjust the guide of the rolling mill. After research, it is concluded that if the rolling guide or closed mill is selected, this kind of failure can be effectively solved, and the effect is very good. If conditions permit, you can try it.
