With the continuous development of society, the metallurgical industry occupies an increasingly important position in the manufacturing field, many fields will be involved in metallurgy, and the application of roller in the metallurgical industry is more and more widely. The quality of the rolling mill roll affects the normal operation, effect and efficiency of the machine tool.

Roll is a tool to produce plastic deformation of metal. It is an important consuming part to determine the efficiency and quality of rolling mill. Roll is an important part of rolling mill in rolling mill. The pressure produced by a pair or group of rolls is used to roll steel. It mainly bears the influence of dynamic and static load, wear and temperature change during rolling.

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.

Among the rolling mill components, the operating conditions of the rolls are the most messy. Residual stress and thermal stress will occur in the preparation process before the roll is manufactured and used. During the working process, it is further subjected to the effects of various periodic stresses, including twists, changes, shear forces, contact stresses, and thermal stresses.

The short stress rolling mill has gradually eliminated the rack housing, so it is also commonly referred to as the houseless rolling mill. The short stress rolling mill has the following characteristics: Easy to achieve negative tolerance rolling, because the high rigidity of the rolling mill guarantees the high precision of the product; Can achieve nominal adjustment.

In the rolling mill production unit, the roller table is an important equipment for mechanization of production, especially in the production unit of section steel and bar, which runs through the entire production line. The roller table is the most common equipment for the rolling line of the entire rolling mill, and each section has a roller table. Due to the different positions of the roller tables, the role played by them is also different.
