Induction heating provides a regulated and localized technique of heating that does not require touch with the components being heated. Heat is produced by passing an alternating magnetic field across electrically conducting objects. An industrial induction heating machine is highly low-cost and typically results in considerable cost reductions compared to other standard process heating methods. Induction heating differs from conventional heating technologies in that it does not use convection or radiation to transfer heat to the product’s surface. Instead, the product’s surface creates heat via current, and the heat from the product’s surface is transported to the product via heat conduction. The electrical reference depth determines the depth of direct heating using induction current.
What is the distinction between medium and high-frequency induction heating equipment?
1. Different frequencies: induction heating equipment with a frequency of 1-10Khz is considered medium-frequency, whereas induction heating equipment with a frequency greater than 50Khz is considered high-frequency.
2. The quenching depth of the two is affected by the frequency of induction heating equipment. The quenching depth of medium-frequency induction heating equipment is typically 3.5-6mm, whereas high-frequency induction heating equipment has a quenching depth of 1.2-1.5mm.
3. Different diathermy diameters: Medium frequency induction heating equipment significantly benefits workpiece diathermy. Its primary application is the diathermic heat treatment of workpieces, and it can perform diathermic heat treatment on workpieces with diameters ranging from 45 to 90mm.
What is an induction hardening machine?
Induction hardening equipment increases the hardness and endurance of steel by using induced heat and quick cooling (quenching). Induction is a non-contact technology that generates intense, localized, and controlled heat fast. Only the component to be toughened is heated using induction.
The principle of the induction hardening machine:
The workpiece is in the copper coil, typically a hollow copper tube with an alternating medium or high-frequency current. In the workpiece, the alternating magnetic field induces a draft of the same frequency. This induced current is unevenly distributed on the workpiece. It is tough on the outside yet frail on the inside. It is the soft core near 0. The workpiece layer may be heated fast, and the hardened surface layer temperature will climb to 800-1000°C in a few seconds, but the core temperature will rise relatively little. The hardness of the heated surface is then augmented by quick cooling.
