In order to extend the life of the roller itself, first of all, we should pay attention to the roller maintenance work. Speaking of its maintenance, we should pay attention to the roller line should be regularly cleaned up the dust and a series of foreign bodies; Then, we should pay attention to the fact that we should check the roller shell and end cover welding place is firm.

Roller lubrication should be good, so that it can be greatly reduced the loss of wear. Next, we are actually to pay attention to should be to avoid equipment overload operation, should extend the service life of the roller.

Next, we will briefly introduce the production requirements of the roller, first of all, the roller should have enough rigidity, about this, in fact, under the action of ensuring a heavy load, for its bending deformation, in fact, should not exceed its allowable value. For its surface, in fact, it should have a sufficient hardness. At this time, we will require it to reach HRC above 50 degrees, and it should have strong corrosion resistance.

For its coating, in fact, it should be to have this strong anti-peeling ability, in this way, that is to ensure that the roller working surface has a good abrasion resistance and corrosion resistance. In terms of its working surface, in fact, it should have a more fine processing, in this way, in fact, it can ensure the size accuracy and its surface roughness.

In terms of its roughness, it should be above Ra0.16 in fact, so there should be no pores or grooves. The wall thickness of the working surface of the roller should be kept even, otherwise, in fact, it will make the temperature of the roller surface is not uniform, in view of this aspect, to a large extent, it will directly affect the quality of products.
