Abstract

The invention discloses a manufacturing method for an annular rail in a drum. The manufacturing method comprises the steps that two long bar steel plates are obtained; a plate rolling machine is used for rolling, curving and forming the two long bar steel plates, and an inner circular ring and an outer circular ring are obtained; a hot assembling manner is used for assembling the inner circular ring into the outer circular ring, the inner circular ring is fixed to the outer circular ring, and the annular rail in the drum is obtained; and stress eliminating treating is conducted on the annular rail in the drum. According to the manufacturing method for the annular rail in the drum, the annular rail in the drum is divided into two layers to be manufactured, rolling, curving and forming are conducted, the inner circular ring and the outer circular ring are formed, and the annular rail in the drum is formed through hot assembling after machining. With the method, large forming equipment does not need to be utilized, manufacturing cost is reduced, meanwhile, the use effect of the product is ensured, and the problems that in a manufacturing method in the prior art, the requirement for the machining capability of equipment is very high, and cost is high are solved.

Description

Technical field [0001] The invention relates to the technical field of manufacturing an annular track in a rotating drum, in particular to a method for manufacturing an annular track in a rotating drum. Background technique [0002] The inner ring track of the drum is an inner ring track with a thickness of more than 140 mm and an inner diameter of about 2 meters. Because the thickness is too large, ordinary equipment cannot be formed. Generally, a super-large plate rolling machine is used to roll forming, then welding, and the finished track is completed by mechanical processing, or the ring forging equipment is used for forging and forming, and the finished product is processed by mechanical processing after heat treatment. These two methods have high requirements on the processing capacity of the equipment, and the cost is relatively high. Summary of the invention [0003] The present application provides a method for manufacturing an annular track in a rotating drum, which so...
