Overview: In the process of hot loading, induction heating is often carried out on metal parts, so that the inner aperture in the negative value is increased to how many wires than the shaft is, or even larger, to meet the needs of interference installation or disassembly, this paper focuses on the induction heater principle, types and methods, convenient for users to select.

Principle of induction heater

The use of eddy current induction heating principle, the workpiece induction heating, not only to ensure that the heating is fast, the workpiece will not be annealed, the inner hole is uniformly heated and the same amount of expansion becomes large, so as to achieve smooth assembly, safe, reliable and stable operation. 

Induction heater type

1, the power frequency heating adopts the power frequency heating principle, that is, 50HZ, the metal workpiece is permeated overall heating, so that the inner hole is uniform and the whole expansion.

2, electromagnetic heating and high temperature wire wound electromagnetic induction heating coil, the workpiece hole or from the outside to the inside heating, this heating method does not need water cooling.

3, high frequency heating high frequency induction heating or medium frequency heating, super audio heating, etc., all belong to this category, and water cooling is used in the copper tube induction heating ring. 

The company specializes in producing all kinds of induction heaters, induction heating and assembly of ring and barreled metal workpieces, which is a heating equipment for fasteners. There are bearing heating, gear heating, coupling, sprocket, piston, motor housing, connecting rod, pulley and so on induction heating equipment.

The core of induction heating equipment is power frequency induction heating, power frequency is not frequency conversion, does not change the metallographic structure of the metal, and maintains the original hardness of the metal. Fast speed, high efficiency, no impact on the human body, only the workpiece is heated, the equipment itself does not heat, more not red, very safe.

Induction heater is easy to control, can achieve temperature, time dual control function, the brand is composed of three groups of pure copper coil, greatly improve the work efficiency and assembly speed, occupy a small area, do not connect water cooling, power saving, skin effect depth heat.

Small and medium-sized workpiece heating has a standard type of heater, large parts generally need to be customized according to the actual needs of various enterprises, heating parts of different shapes, different sizes, different tons of weight, power is not the same, we are manufacturers, design, drawing, production - seamless docking, manufacturing induction heating equipment more ideal, better use
