1. The surface hardness of the quenched and tempered metal workpiece is high. The surface hardness of the quenched and tempered workpiece by medium frequency induction heating is often 2~3 HRC higher than that of ordinary quenching. The impact toughness, fatigue strength and wear resistance of the metal after quenching and tempering of the bar are greatly improved. The service life of metal workpieces can be greatly improved by quenching and tempering the bar of the induction furnace;
2, induction furnace bar quenching and tempering metal workpiece non-integral heating, so the overall deformation is small; 3, bar quenching and tempering metal workpiece heating time is short, the surface oxidation and decarburization amount is small;
4. The bar material quenching and tempering heating source is carried out on the surface of the metal workpiece, and the heating speed is fast and the efficiency is high; 5. The structure of the induction furnace bar material quenching and tempering equipment is more compact than that of ordinary metal heating equipment, and it is convenient to use;
6, bar quenching and tempering medium frequency induction furnace to achieve mechanization and automation of heat treatment processing, saving labor costs; 3. bar quenching and tempering induction quenching and tempering of the metal workpiece performance.
1. The surface hardness of metal workpieces after quenching and tempering of bar materials is greatly improved: the surface hardness of workpieces quenched by intermediate frequency induction heating is often 2~3 HRC higher than that of ordinary quenching; 2. Wear resistance of bar materials after quenching and tempering. Generally speaking, the wear resistance of workpieces after intermediate frequency quenching is higher than that of ordinary quenching;
3. The fatigue strength of bar material after quenching and tempering, in principle, the fatigue strength is greatly improved by intermediate frequency surface quenching, and the notch sensitivity is decreased.
