A kind of looper wheel with detachable wear-resistant layer

Abstract

The invention relates to a loop wheel with a detachable wearing layer. The loop wheel is characterized by comprising a guide wheel shaft, wherein a bearing is mounted on the guide wheel shaft; a check ring is arranged on the upper part of the guide wheel shaft; the check ring is used for fixing; the loop wheel further comprises a positioning sleeve; the bearing is mounted in the positioning sleeve; a first end cover and a second end cover are respectively arranged at upper and lower ends of the loop wheel. The design is more suitable for the rolling of high-speed wire rod products; the exchanging times of the loop wheel can be greatly reduced; the steel ratio is increased; the yield in one shift is greatly promoted; the labor intensity of on-site workers is relieved; the production is stabilized; at the cost aspect, only the worn sleeve is exchanged, and the other parts can be repeatedly used, so that the cost of spare parts is greatly reduced.

Description

technical field [0001] The invention relates to a looper wheel, in particular to a looper wheel with a detachable wear-resistant layer, and belongs to the technical field of steel rolling equipment. Background technique [0002] With the improvement of steel rolling equipment level, the grade of industrial material rolling in our country is getting higher and higher, and the requirements for the surface quality of the rolled material are becoming more and more strict. How to reduce the surface scratches of the rolled material during the rolling process is particularly important, such as for cold heading When rolling with wire and bar, scratches or cracks of about 0.04mm on the surface will crack in 1 / 3 of the cold heading test, so the surface protection of the rolled piece during the rolling process is particularly important. At present, there are many wheels in the looper device used in the rolling mill. Surface wear directly affects the quality of the wire surface, especia...

AI Technical Summary

Problems solved by technology

Loop wheels in steel mills are generally made of alloy steel. After wear and tear, the wheel assembly structure needs to be completely disassembled and disassembled. After disassembly, the bearings are basically unusable. The wheels are surfacing with stainless steel electrodes, and then they are used after finishing. Repeated use requires repair. Long process and high cost
