High-frequency induction heating equipment characteristics and advantages
Time:2014-07-16 20:53:28
The main advantage of induction heating are: ① do not have the overall heating, deformation of the workpiece, power consumption is small. ② pollution. ③ heating speed, surface oxidation and decarbonization lighter. ④ surface hardened layer can be adjusted as needed, easy to control. ⑤ heating equipment can be installed in machining production line, easy to implement mechanization and automation, easy to manage, and can reduce transportation, saving manpower, improve production efficiency. ⑥ hardened layer of fine martensite, hardness, strength and toughness are higher. ⑦ After the surface has hardened workpiece surface compressive stress within the larger, higher workpiece fatigue breaking capacity. 
Induction heat treatments have some drawbacks. Compared with flame hardening, induction heating equipment is more complex, and poor adaptability, for some complex shape of the workpiece is difficult to guarantee quality. 
Induction heating is widely used for surface hardening of gears, shafts, crankshafts, cams, rollers and other parts, with the aim to improve the wear resistance of the workpiece and the fatigue resistance to breaking. After the vehicle axle induction heating surface hardening, fatigue cycles under design load increased by 10 times compared with the quenched approx.
