Working principle

  Induction heating is an advanced metal heating technology and one of the energy-saving and emission-reduction technologies advocated by the state. It uses the induced current generated by the metal conductor under the action of the alternating magnetic field to cause self-heating, and achieve the purpose of heating the metal. Now Ketchan high-frequency induction heat treating machine is widely used in metal heat treatment, quenching, diathermy, smelting, welding, heat sleeve, and many other fields. Induction heating has significant advantages such as non-contact, fast speed, high efficiency, simple process, easy automation, etc., and has the advantages of zero emission, no pollution and energy saving, which is of great significance to the development of the national economy.

Frequency leves

  High frequency induction surface heat treating machine can be divided into intermediate frequency quenching (<10KHZ), ultrasonic quenching (20-100KHZ), high frequency quenching (>100KHZ) according to the heating frequency; according to the heating part, it can be divided into outer surface quenching and inner surface quenching (internal surface quenching). The quenching method can be divided into the simultaneous heating and quenching method and the continuous scanning quenching method.

Surface induction heat treating advantages

  1. The surface hardness of the workpiece is high, and the workpiece surface quenched by high and medium frequency induction heating is often 2 to 3 units (HRC) higher than ordinary quenching. The notch sensitivity is small, and the impact toughness, fatigue strength, and wear resistance are greatly improved. It is beneficial to exert the potential of materials, save material consumption, and improve the service life of parts;
  2. Because the workpiece is not heated as a whole, the deformation is small;
  3. The heating time of the workpiece is short, and the amount of surface oxidation and decarburization is small;
  4. The heat source is on the surface of the workpiece, the heating speed is fast, and the thermal efficiency is high;
  5. The equipment is compact, easy to use, and has good working conditions;
  6. Easy to mechanize and automate.

Performance after induction case hardening

  1. Surface hardness: The surface hardness of workpieces subjected to high and medium frequency induction heating surface heat treating is often 2 to 3 units (HRC) higher than ordinary quenching.
  2. Wear resistance: The wear resistance of the workpiece after high-frequency induction heat treating is higher than that of ordinary quenching. This is mainly due to the combined results of fine martensite grains in the hardened layer, high carbide dispersion, relatively high hardness, and high compressive stress on the surface.
  3. Fatigue strength: high and medium frequency surface quenching greatly improves fatigue strength and reduces notch sensitivity. For workpieces of the same material, within a certain range, the fatigue strength increases with the increase of the depth of the hardened layer, but when the depth of the hardened layer is too deep, the toughness of the core decreases, and the fatigue strength decreases, and the brittleness of the workpiece increases.

Applications of induction heat treating machine

  In the manufacture and production of mechanical equipment such as automobiles and machine tools, there are many workpieces of transmission mechanisms that need to bear large loads and frequent start and stop, so the surface needs to have high hardness, strength, and wear resistance, while the core Better toughness is required. For example gears, camshafts, valve rods, forward rods, automobile half shafts, spline shafts, sprockets, optical shafts, guide rails, profiling parts, etc. Therefore, surface heat treatment is required for these workpieces. The traditional surface heat treatment includes surface carburizing, nitriding; carbonitriding; surface quenching, etc. Compared with other heat treatment processes,high frequency induction surface heat treatment has lower cost, higher efficiency, and greater deformation It is small, the operation is simpler, the advantages are very obvious, and it is widely used in industrial production.
