DSP Digital Control Medium Frequency Induction Hardening Machine For Hardening
WHAT IS INDUCTION HEATING:
Induction heating, an applied energy process, is a selective, noncontact heating method that can be performed in air on the shop floor as well as under a protective atmosphere or in a vacuum furnace. Induction heating involves an electrically conductive material such as steel (the workpiece), an induction power source, an induction coil assembly (usually copper), and the ability to quench.
Induction heating requires a power source. A coil assembly is attached to the power source, and the workpiece is placed inside the coil. Current from the power source flows through the coil, creating invisible lines of force that issue from the coil. These lines of force induce eddy currents in the workpiece, resulting in heat. Parts can be heated to a broad range of temperatures before quenching, depending on the desired outcome.
Most notably used in the automotive industry, induction heating has several key benefits. Long process times and high surface temperatures are not required, since heat is generated within the workpiece itself, not transferred by radiation or convection. Induction heating’s quick processing time is a significant advantage for heat treaters working with high-volume parts.

14. The internal components of the equipment are reasonably laid out, and the main control circuit board is placed on the weak current side to avoid interference of the strong electricity to the control circuit and improve the control precision;
15, Electromagnetic induction heating power supply should have remote control function, and use digital circuit control, power adjustment can be adjusted from 0% to 100% resolution using 0.1% level or 0. 01% level output stability can reach 0. 3% or 0. 025%; At the same time, the digital PID temperature control module can be configured to preset the target temperature of the ( (the temperature measurement method is infrared temperature measurement or thermocouple temperature measurement), automatically complete the power adjustment during heating, and control the temperature. The precision is + 1 ℃ .
GuangYuan series new DSP series Medium frequency, Super-audio frequency, High frequency and Ultrahigh frequency induction heating equipment adopts DSP+FPGA structure with all-digital high-efficiency and precise control technology, which can automatically track the resonant frequency and ensure that IGBT is always in any situation. ZCS or ZVS is the soft-switching state, which makes the IGBT work state optimal, its own power consumption is smaller, and the whole machine is more efficient. It completely solves the shortcomings of the analog circuit, and ensures the stability of the whole system. The external interface and simple human-machine interface make the connection between the equipment and the production line more convenient.
APPLICATION FOR INDUCTION HEATING TECHNOLOGY:
The vigorous development of the auto industry has brought unprecedented development opportunities to the auto parts industry. Induction heating technology is also being used more and more widely in the field of automobile manufacturing.
In terms of smelting, casting is a metal processing method that is easy to shape. The casting method can be used to make parts of various sizes and complex shapes on automobiles. It can be said that the best use is made in the development of the automobile industry. Almost all casting processes can do their best in the automobile industry.
The main smelting processes used in the production of foundry auto parts at home and abroad are cupola smelting process, intermediate frequency induction electric furnace smelting process and cupola-medium frequency induction electric furnace dual smelting process. Induction melting furnaces are also gaining in the foundry industry due to their technical advantages.
In terms of heating, according to statistics, in the former Soviet Union, induction heat-treated parts in the automobile industry accounted for 40% to 45% of heat-treated parts. The application and development of induction heating technology is self-evident today.
