Description

Technical Field

[0002] High-frequency induction heating is a method of heating an electrical conductor using electromagnetic induction. When heating, eddy currents are generated in the metal, causing Joule heating of the metal due to resistance. The induction heater consists of an electromagnet through which high-frequency alternating current passes. Induction heating equipment is widely used in the processing of pipes due to its high heating efficiency.

[0003] According to application number 202220158152.4, a high-frequency induction heating device for pipe processing includes a heating chassis and an extended pipe processing box. An insulating mounting frame is fixedly installed at the bottom of the inner wall of the heating chassis, and an induction heating component located inside the heating chassis is fixedly installed on the top of the insulating mounting frame. The induction heating component includes an insulating sleeve, a high-frequency induction coil and a ceramic sleeve.

The iron shavings generated during the processing can be collected uniformly to avoid environmental pollution. However, pipe heating may be accompanied by chemical reactions, which may produce waste gas, but the device only processes the waste slag and does not exhaust the waste gas, which will pollute the environment.
