Problems solved by technology
[0004] Especially at present, the welding and post-weld heat treatment of rails on the track site are carried out separately by using different devices or equipment. First, the degree of automation is low and the labor intensity is high, which leads to low organization efficiency and long construction period of rail construction; second, welding And heat treatment treatment is easily affected by various human factors, resulting in unstable quality of rail welded joints after welding and heat treatment
Third, the purchase cost of the equipment is relatively high, and the requirements for the construction site are increased

Description
technical field [0001] The invention relates to welding and heat treatment of steel rails, in particular to induction butt welding and heat treatment equipment of steel rails. Background technique [0002] Induction welding is a method of heating the workpiece by using the eddy current effect on the workpiece in the alternating magnetic field-electric field induction to melt the workpiece, thereby realizing welding, which belongs to a kind of pressure welding. Induction heating can be divided into: high frequency induction heating (100 kHz~1000kHz), medium frequency induction heating (1kHz~10kHz) and power frequency induction heating (50Hz) according to the frequency of the current used. Medium frequency (1~10KHZ) heating depth is 2-10mm, generally used for heating shafts with large diameter and large and medium forging workpieces. [0003] Taking rail induction butt welding as an example, after the induction butt welding is completed, the joint structure, especially the au...
