Super audio induction heating machine

1. 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 high frequency of the electron tube; 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 Germany imported power device IGBT 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. I produced the ultra-audio frequency induction heating machine from 16KW 230KW .

 2. 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. 
 Third, the advantages of super audio frequency induction heating machine :
1. The equipment is easy to operate and does not require professional training.
2. The highest heating efficiency, the fastest speed, low consumption, energy saving and environmental protection.
3. The heating power and time can be adjusted, which is beneficial to improve the heating quality and heating repeatability , and can simplify the operation of workers.
4. It replaces dangerous gas and other dangerous gas heating production without open flame, which is more in line with national fire safety regulations.
5. The power supply produced by our company has fast start-up, high quality and low price, safe and reliable, long service life, easy operation, energy saving and environmental protection

5. 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 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

6. Precautions for the use of super audio frequency induction heating machine

1 In   order to prevent electric shock, please ensure that the chassis is grounded according to the electrical specifications.

2 The   disassembly and installation of the sensor must be carried out after the heating stops.

3    Strictly implement the principle of first connecting water and then electrifying. Water shortage is strictly prohibited during the working process. The water quality and pressure of the cooling water inside the equipment and the sensor must meet the requirements of Table 2. In order to avoid blocking the cooling pipeline, if the water supply is supplied by a water pump, please install a filter at the water inlet of the water pump. The cooling water temperature cannot be higher than 45 ℃, and the water flow rate is 10T/h (softened water is recommended)

4 The    equipment should be protected from sunlight, rain, humidity, dust, etc. When the equipment needs to be repaired or maintained, it must be done one hour after the power is cut off.

5 The    cleaning method inside the machine is blown with compressed air or a fan every week. The circuit board is cleaned with a brush, and then blown off.

6    Ordinary users should clean the machine waterway with a special descaling agent (available by our company) every months. When the machine frequently alarms the water temperature, or when the water flow at the outlet is observed to be significantly reduced, it should be cleaned immediately.

7 The    sensor should be kept clean to prevent short circuits between turns.

8    Single-turn inductors cannot be used with this equipment. Otherwise, the inductance may be too small and the equipment may be damaged. In special circumstances, please consult the manufacturer.

9 When    replacing the sensor, the contact surface between the sensor connection board and the transformer should be polished clean with sandpaper to maintain good conductivity.

Seven, the cooling water configuration method of the 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.
