What are the advantages of using high-frequency induction heating equipment for surface heat treatment of workpieces?

Under the premise of not changing the chemical composition of the workpiece surface, the surface heat treatment process of the workpiece is to change the microstructure and performance of the workpiece surface through high-frequency induction heating equipment. This not only improves the fatigue resistance of the workpiece, ensures that the core has sufficient strength and toughness, but also makes the surface of the workpiece obtain higher hardness and good wear resistance, and the surface heat treatment of the workpiece further strengthens the performance of the workpiece , so that it can be better used in production.

Facts have proved that the use of high-frequency induction heating equipment for surface heat treatment of workpieces is a very energy-saving and economical heat treatment method. The workpiece after heating is equivalent to forming a composite material, which can quickly change the critical point temperature of the workpiece, the heating speed is fast, the time is short, the workpiece is heated and cooled within a few seconds or tens of seconds, the production efficiency is high, and the oxidation and decarburization few. The quality is stable during the heating process, so that the austenite grains are fine and uniform, and a very fine martensite structure can be obtained after quenching, with high surface hardness, good brittleness and high fatigue limit. Partial heating of the workpiece can be carried out, but only the surface of the workpiece is heated, the deformation is small, and the sensitivity to the gap is small. This process is very suitable for manufacturers of mass production, which improves the working conditions and production environment, and facilitates the realization of mechanized and automated production by manufacturers.

High-frequency induction heating equipment has a wide range of applications, not only for quenching and tempering treatment of slender shaft workpieces, but also for local heat treatment of workpieces and surface quenching of carburized parts. It is an effective means to improve the fatigue strength and service life of the workpiece, and the impact resistance increases with the increase of the hardened layer.
