30kw end bar induction Heating Machine 50 kg heat induction Heating Machine Heat Induction Machine for forging
Principle of Induction Heating:
Put the workpiece into the inductor (coil), when an alternating current of a certain frequency is passed through the inductor, an alternating magnetic field will be generated around it. The electromagnetic induction of the alternating magnetic field produces a closed induced current in the workpiece eddy current. The distribution of the induced current on the cross-section of the workpiece is very uneven, and the current density on the surface of the workpiece is very high and gradually decreases inward. This phenomenon is called the skin effect. The electric energy of the high-density current on the surface of the workpiece is converted into heat energy, so that the temperature of the surface is increased, that is, surface heating is realized. The higher the current frequency, the greater the current density difference between the surface and the interior of the workpiece, and the thinner the heating layer. After the temperature of the heating layer exceeds the critical point temperature of the steel, it is rapidly cooled to achieve surface quenching.
Features and Applications
The main advantages of induction heating are:
1.No overall heating is necessary, the deformation of the workpiece is small, and the power consumption is small.
2.No pollution.
3.The heating speed is fast, and the surface oxidation and decarburization of the workpiece is lighter.
4.The surface hardened layer can be adjusted as required, which is easy to control.
5.The heating equipment can be installed on the mechanical processing production line, which is easy to realize mechanization and automation, easy to manage, and can reduce transportation, save manpower, and improve production efficiency.
6.The martensite structure of the hardened layer is finer, and the hardness, strength, and toughness are higher.
7.After surface quenching, the surface layer of the workpiece has a larger compressive internal stress, and the workpiece has a higher fatigue and fracture resistance.Induction heat treatment also has some disadvantages. Compared with flame quenching, induction heating equipment is more complicated and has poor adaptability, and it is difficult to guarantee the quality of some complicated workpieces.
