Steel rail utilization rate increasing method based on heel end precision forging line

Abstract

The invention provides a steel rail utilization rate increasing method based on a heel end precision forging line. The method comprises the following steps that firstly, the 0-point position of a stokehold feeding mechanism is adjusted towards the direction of a forming section, the 0-point position of the stokehold feeding mechanism is moved from the farthest stroke to the forming section by L mm, and the heating length is shortened by L mm from the original length; and secondly, a furnace body of an intermediate frequency heating furnace is adjusted by L mm towards the direction of raw materials, and an infrared 0-position positioning point and the furnace body synchronously move by L mm towards the direction of the raw materials. According to the method, on the basis that the overall scheme of stokehole feeding operation is not changed, the shortest feeding length of a feeding system is greatly decreased to 5190 from 6450 according to the length of a rail part forged and pressed product, the industry bottleneck is broken through, and the steel rail utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a method for improving the utilization rate of rails based on a heel end precision forging line. Background technique [0002] The rail heel-end pressing automatic feeding system has been used in the turnout industry so far, and it has played a positive role in improving the production efficiency of the heel-end pressing and improving the overall process and equipment level of the heel-end forging. However, compared with the traditional manual feeding operation, the automatic feeding system also has certain disadvantages. The most obvious shortcomings are two points. One is that the forging static positioning of the rail parts cannot be controlled; the other point is that the original rail parts cannot be realized. Profiling with the shortest blank length. [0003] At present, the minimum feeding length of the common feeding system in the industry is 6450, and in extreme cases,...
