Super audio induction heating machine

A. Overview: The super audio frequency is higher than the traditional intermediate frequency (10KHZ) and lower than the traditional high frequency (100KHZ); the super audio frequency band of our company is set at 15-35KHZ.

Therefore, the hardened layer is shallower than the intermediate frequency, and deeper than the tube high frequency; it fills the process gap that sometimes the intermediate frequency quenching of some parts is too deep and the high frequency quenching is too shallow. It is very suitable for quenching small and medium-sized workpieces, and the hardened layer of the workpiece is about 1-2.5mm.

The super audio frequency induction heating machine of our company adopts the power device IGBT imported from Germany as the characteristic device, and the circuit adopts series resonance. There is a safe voltage on the sensor. Small size, light weight, convenient installation and operation, energy-saving and power-saving, it is an ideal choice for workpiece quenching equipment. The super audio frequency induction heating machine produced by our company ranges from 16KW to 230KW. 

B. Super audio frequency induction heating equipment is widely used in: 

1. High-frequency quenching treatment of various auto parts and motorcycle parts. Such as: crankshafts, connecting rods, piston pins, crank pins, sprockets, camshafts, valves, various rocker arms, rocker shafts; various gears in the gearbox, spline shafts, semi-transmission shafts, various small shafts , Quenching heat treatment of various shift forks, brake hubs, brake discs, etc.;

2. Heat treatment of various hardware tools, hand tools and knives. Such as the quenching of pliers, wrenches, screwdrivers, hammers, axes, kitchen knives, sugarcane knives, sharpening rods, etc.;

3. Guiding shoe quenching and slide quenching equipment for coal mines;

4. High-frequency quenching of various hydraulic and pneumatic components Heat treatment. Such as the column of a plunger pump;

5. Heat treatment of metal parts. Such as high-frequency quenching treatment of various gears, sprockets, various shafts, spline shafts, pins, etc.; single-tooth quenching heat treatment of large gears;

6. Quenching treatment of machine tool bed rails in the machine tool industry;

7. Plug and rotor pumps The rotor; the quenching treatment of the reversing shafts on various valves, the gears of gear pumps, etc.

D.What is the difference between super audio frequency induction heating machine and medium frequency induction heating equipment?

Super audio frequency induction heating machine : It has a hardening depth of 0.5 to 2 mm (millimeters), which is mainly used for small and medium-sized parts that require a thin hardened layer, such as small modulus gears, small and medium-sized shafts, etc.

Medium frequency induction heating equipment :

Effective hardened depth of 2 ~ 10 mm (millimeters), required for the hardened layer is mainly required deeper parts such as gears medium modulus, high modulus gear, larger diameter shaft.

Is the difference in thickness

E.Cooling water configuration method for super audio frequency induction heating machine

The interior of the high-frequency heating equipment and the inductor must be cooled by water, and the water quality must be clean, so as not to block the cooling pipeline. If the water supply is pumped by a water pump, please install a filter at the water inlet of the water pump. The temperature of the cooling water should not be higher than 45C , otherwise it will cause the equipment to alarm and even overheat damage. Specific requirements must be prepared according to the table.
