Working principle of mechanical parts quenching shaft quenching IGBT ultrasonic frequency induction heating equipment

After the induction heating equipment outputs a strong alternating frequency current, a strong alternating magnetic field is generated through the induction coil. Under the action of the magnetic field, the heated working surface forms an eddy current, which quickly makes the workpiece heat up.

灵蛇网4818A. Fast heating: the heating speed is less than 1 second, and the heating speed can be adjusted and controlled.

B. Wide application: it can heat various metal workpieces. (Induction coils are made according to the shape of the workpiece)

C. Low power consumption: Therefore, compared with other heating methods (such as gas, oxygen, acetylene, coke, coal, electric furnace, high-frequency electronic tube, etc.), it can save energy.

D. Good effect: the surface of the workpiece is heated evenly and the temperature rises quickly, which reduces the degree of deformation of the oxide layer on the surface of the workpiece and the workpiece.

灵蛇网4818E. Small footprint: The equipment is small in size, light in weight, and takes up less than half a cube of space, making it easy to move and move.

F. High efficiency: The equipment has automatic functions, and the operation can be completed by one person, thereby reducing the process and improving the efficiency.

G. Easy to operate: CNC type design, the whole machine does not need to be debugged, the installation and operation are very convenient, and it can be learned in 5 minutes.

H. Good environmental protection: no noise, pollution and open fire, it is easier to meet the requirements of environmental protection and fire protection.

Ultra-audio induction heating equipment is an energy-saving product in line with the National Twelfth Five-Year Plan. It uses IGBT as the main device, the power circuit is characterized by series oscillation, and the control circuit is characterized by automatic frequency tracking and multiple closed-loop control. Ultra-audio induction heating equipment is highly integrated and modular. High efficiency, stable performance, safe and reliable.

Ultrasonic induction heating equipment is mostly used for surface quenching of industrial metal parts. It is a metal heat treatment method that generates induced current on the surface of the workpiece, rapidly heats the surface of the parts table, and then quickly quenches it. Ultrasonic induction heating equipment, that is, equipment for induction heating of workpieces for surface quenching

灵蛇网4818Ultrasonic induction heating equipment can use the following tips to improve quenching efficiency during quenching:

1. When the ultrasonic induction heating equipment is quenched, adding salt to the water can double the cooling rate. The cooling rate of salt water quenching is fast, and there is no phenomenon of quenching cracks and uneven quenching. It can be called an ideal coolant for quenching.

灵蛇网48182. The quenching liquid of the ultrasonic induction heating equipment should be quenching liquid with impurities in the water quality, because impurities in the water are more suitable than pure water. Adding solid particles to the water helps to clean the surface of the workpiece, destroy the effect of the vapor film, and make cooling The increased speed prevents the occurrence of quench spots. Therefore, it is a very important concept to use the quenching technology of mixed water instead of pure water for quenching treatment.

3. The water-soluble quenching fluid can be prepared by mixing polymer and water: the polymer quenching fluid can be prepared according to the degree of water added to the quenching fluid with the cooling rate from water to oil, which is very convenient and free from fire, pollution and other public hazards. consider.

When selecting induction heating equipment, different types of induction heating equipment should be selected according to the characteristics, hardness, size, and degree of quenching of the workpiece.
