Abstract

The invention relates to a roller supporting roller for controlling edge shoulder shedding and peeling. The fatigue resistance of the supporting roller is greatly improved by comprehensively optimizing the roller profile curve of the supporting roller, especially the power function roller profile curve of the edge on the premise of not influencing the straightness of a rolling mill and the convexity control capability of a plate, so that the long-term use of the supporting roller is realized, the probability of shoulder shedding and peeling of the edge of the supporting roller of the rolling mill is effectively reduced, and the problems that due to shoulder shoulder shedding and peeling of the edge of the supporting roller, roller losses are serious, the production quality is reduced, andcost is increased for a long time are solved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a roll back-up roll for controlling side shoulder and meat loss. Background technique [0002] Rolls have a great impact on various technical indicators such as increasing output, ensuring quality, and reducing consumption in steel rolling production. Reducing roll consumption has become an important way for various steel rolling production enterprises to save energy and reduce consumption. [0003] However, in the process of rolling steel, it is often found that continuous roll surface peeling occurs along the roll diameter direction at the edge of the roll surface of the roll. "Shoulders off" or "flesh off". In severe cases, large pieces of peeling may even appear on the edge of the roll, resulting in roll failure. The field use shows that the roll edge shoulder and meat drop have different degrees in the back-up rolls and work rolls, but the proportion of the back-up r...
