Rolls are important parts of rolling mills. They use the pressure generated by a pair or a set of rolls to roll steel. It mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling.

Take the common SWC350BH universal joint shaft as an example. After calculation, the clearance space in a single bearing sleeve is about 97000mm³without oil injection. As the assembly generally uses a four-point lubrication method, during assembly of the assembly, the operator will pre-lubricate the bearings in the four directions one by one. Some users sometimes encounter the situation that the oil cannot be added.

The spalling form of hot rolling work roll is different from that of fracture surface and support roll. The former mainly occurs in the upstream racks of hot tandem mills, and most of them are small pieces of spalling, resulting in pits or ellipsoidal pits on the surface of the rolls, which are distributed in the range of the roll body in contact with the rolling piece.

Cast steel rolls can be divided into two categories: steel rolls (carbon content 0.4-1.4%) and semi-steel rolls (carbon content 1.4-2.4). Steel rolls have low carbon content, so their hardness is low, and their structure is generally composed of iron.
