Abstract
Description
Technical Field
[0001] The utility model belongs to the field of seamless steel pipe production, and specifically relates to a core rod polishing device. Background Art
[0002] The mandrel is an important production tool for rolling seamless steel pipes. It plays an important role in reducing the diameter and wall of steel pipes and improving the quality of the inner surface of steel pipes. Therefore, there are certain requirements for the surface finish of the mandrel. In the actual production process, the mandrel has to withstand large radial pressure, axial tension, friction from the inner surface of the steel pipe, and frequent hot and cold alternation. After long-term use, the surface of the mandrel is worn and cannot meet the production requirements. Cutting the worn mandrel, removing the uneven surface, and then polishing it can obtain a mandrel with a smaller radius but a surface that meets the production requirements, thereby realizing waste utilization. Polishing the mandrel separately after cutting is a cumbersome process and wastes manpower and material resources. Utility Model Content
