20KW ultra-high frequency induction heating machine for rivet heating machine

Main specifications and parameters:

Main applications and features: 
This product is suitable for many heating purposes, such as:

( 1 ) Carbide serrated welding

( 2 ) small shaft and small parts of the heat treatment

( 3 ) diameter less than 5mm stainless steel or alloy steel filaments annealing or quenching.
ZG-UHF Series device structure using our third generation inverter control technology, using MOSFET tube as a power device, the output frequency of the device up to 1.1 MHz , small power equipment, physical low, suitable for heating a number of small parts, especially in the brazing tooth carbide welding industry has a wide range of applications.
The main advantage of induction heating is

　　① do not have the overall heating, the workpiece deformation is small, the power consumption is small.

　　② pollution. 

　　③ heating speed, less surface oxidation and decarbonization. 

　　④ surface hardened layer can be adjusted as needed, easy to control. 

　　⑤ heating equipment can be installed in the mechanical processing production line, easy to implement mechanization and automation, easy to manage, and can reduce the transport, saving manpower, improve production efficiency. 

　　⑥ hardened layer of fine martensite, hardness, strength and toughness are higher. 

　　After surface hardening of the workpiece surface ⑦ have larger compressive stress, anti-fatigue workpiece higher breaking capacity.

Induction heating heat treatment also has some drawbacks

　　Compared with the flame hardening, induction heating equipment more complex, and poor adaptability to certain complex shape of the workpiece is difficult to guarantee quality. 

　　Induction heating is widely used for surface hardening gears, shafts, crankshafts, cam, rollers and other parts, aims to improve the wear resistance of these artifacts and the ability of anti-fatigue breaking. After the vehicle axle induction heating surface hardening, fatigue cycles under design loads higher than quenching with approximately 10 -fold.Induction heating surface hardening of the workpiece material is usually carbon steel. In order to meet the special needs of certain artifacts, it has been developed for induction heating surface hardening a dedicated low-hardenability steel.High-carbon steel and cast iron workpieces can also employ induction heating surface hardening. Quenching medium commonly used in water or polymer solution.
