Abstract

The invention provides a pass for producing I-shaped steel and a rolling method for the I-shaped steel, including multi-pass passes, and the heated scrap rails are passed through multiple pass passes for reasonable re-rolling, The advanced rail head and rail bottom are deformed, and then the overall deformation is carried out, and finally I-shaped steel is formed. The goal of high-efficiency green reuse has been achieved, resources have been saved, and production costs have been reduced.

Description

A kind of pass for producing I-shaped steel and rolling method of I-shaped steel technical field The invention belongs to the metal processing field, be specifically related to a kind of production for producing the pass of I-shaped steel and the rolling of I-shaped steel manufacturing method. Background technique [0002] The high-speed development of today's railway track transportation industry, the steel rails replaced by railways and the process of producing steel rails every year. The number of unqualified rails is huge, and the reuse of these scrap rails is a lesson of great value and development prospects question. Existing utilization of scrap rail mainly includes the following modes: (1) serve as scrap steel, and recycle it after returning to the furnace for smelting. Use; (2) to make handicrafts; (3) to make tools. The method of the first kind of reuse is the mainstream, but the alloying elements in the steel rail of this reuse method and the current sta...
