Product Description

The induction heating quenching machine often used in gears, bearings, shaft parts, valves, cylinder liners and various Quenching and heat treatment of mechanical parts. It has the characteristics of high melting efficiency, good power saving effect, uniform metal composition, less burning loss, fast temperature rise, and easy temperature control. It is suitable for various metals Smelting occasion.

Advantages of Induction Heating Machine

  • Constant power output, faster melting speed and more obvious power saving effect.

  • The zero-pressure frequency sweep software starts, which can better meet the requirements of frequent starts.

  • The production operation is simple, the material in and out is flexible, and the degree of automation is high, which can realize online production;

  • The heating speed of the workpiece is fast, the oxidation and decarburization is less, the efficiency is high, and the quality of the forging is good;

  • The heating length, speed and temperature of the workpiece can be precisely controlled; the workpiece is heated evenly, the temperature difference between the core and the surface is small, and the control accuracy is high;

  • The integrated design of the sensor furnace body, different sensors are designed with quick-change joints, which is simple and convenient to replace;

  • All-round energy-saving optimization design, low energy consumption, high efficiency, and lower production cost than coal-fired production;

  • Meets the requirements of environmental protection, has little pollution.
