AI Technical Summary

Problems solved by technology

When the straightening roller is in use, due to the relatively high strength and hardness of the metal to be processed, the surface stress of the straightening roller is relatively large. After working for a long time, the surface of the straightening roller will appear very serious wear. After severe wear and tear, it has to be scrapped. In this way, resources are wasted on the one hand, and work efficiency is also affected on the other.

Abstract

The invention discloses an improved straightening roll, belongs to the field of straightening machine accessories, and aims to overcome the defects of easiness in wearing, low working efficiency and waste of resources in the conventional straightening roll. According to the adopted technical scheme, the improved straightening roll comprises a roll body, wherein an inner sleeve is arranged inside the roll body; at least one potting groove is formed in the inner sleeve; the inner sleeve and the roll are integrated by potting; a surfacing alloy layer is formed on the working surface of the roll body; an oxide ceramic layer is formed on the outer surface of the surfacing alloy layer. The improved straightening roll has the advantages of reasonable structure, long service life and high product quality.

Description

Technical field [0001] The invention relates to an improved straightening roller, belonging to the field of straightening machine accessories. Background technique [0002] Straightening roller is one of the indispensable process accessories in the production of section steel, steel pipe and strip. When the straightening roll is in use, due to the relatively large strength and hardness of the metal to be processed, the surface stress of the straightening roll is relatively large. After the straightening roll is used for a long time, its surface will appear very serious wear. After severe wear and tear, it will have to be scrapped. This will waste resources on the one hand and affect work efficiency on the other. In addition, the quality of the straightening roll will directly affect the quality of the product, so how to improve the quality and service life of the straightening roll is very important and necessary. Summary of the invention [0003] The purpose of the present inv...
