Opening type water cooling rail induction normalizing coil and use method thereof

Abstract

The invention relates to the technical field of construction of rails and track traffic and particularly relates to an opening type water cooling rail induction normalizing coil relative to rail welding connector processing. The coil is characterized in that a profiling principle is applied, independent tubes and circuits are arranged on the left coil and the right coil of the induction normalizing coil, current and water flow pass in the pipeline, the water flow and the current in the left coil and the right coil are not communicated, two copper tubes which are arranged on two sides respectively are connected in parallel, the left coil and the right coil are bolted in an insulating mode at the corner position of the rail bottom of one side of the rail, and the profiling rail installation is conducted. The normalizing heating temperature is even, the electricity-magnet-heat conversion rate is improved, a water / electricity supplying circuit is a water-cooling soft connection cable, the flexibility is good, all directions can move in a large range, different condition requirements can be met, the coil is convenient to assemble and disassemble, long in service life, low in cost, energy-saving, environment-friendly and safe in operation and rail connector normalizing quality is stable.

Description

[technical field] [0001] The invention relates to the technical field of railway and rail transit track construction, in particular to a split-type water-cooled rail induction normalizing coil and a method for using the same. [Background technique] [0002] Normalizing is to heat the workpiece to the critical temperature Ac or Accm above 30-50°C, where Ac refers to the final temperature at which free ferrite completely transforms into austenite during heating, and Accm refers to the complete austenitic temperature of hypereutectoid steel during actual heating. Bulk critical temperature line. After holding for an appropriate time, cooling in still air is a metal heat treatment process after complete austenitization. The main purpose of normalizing is to refine the grain and uniformize the distribution of carbides, remove the internal stress of the material, and reduce the stress of the material. Hardness, improving the performance of steel, obtaining a structure close to a b...

Problems solved by technology

[0004] The purpose of the present invention is to solve the deficiencies and defects in the prior art, and provide a split-type water-cooled rail induction normalizing coil which is novel in structure, safe and reliable, energy-saving and environmentally friendly, and effectively solves the problem of inconvenient disassembly and assembly and leakage of circulating cooling water. It is characterized in that the induction normalizing coil is composed of left and right sides, the coils on both sides are independent pipes and lines, the current and water flow pass through the pipes, the water flow and current in the coils on both sides are not connected, the left and right There are two copper tubes connected in parallel in each of the two side parts, and the coils on both sides are insulated and bolted at the bottom corner of the rail on one side, and installed on the profiling rail. The connecting copper block uses two M6 screws to connect the coils on both sides to achieve profiling installation. The top of the coil is connected with the generator power supply and the water tank with a water-cooled flexible connection cable
