IGBT (Insulated Gate Bipolar Transistor) induction heating power supplies operate by converting AC power into high-frequency AC power, with IGBTs serving as the core switching devices for precise control. During the inversion process, IGBTs adjust the output frequency and power to meet various heating requirements. The high-frequency AC current in the induction coil generates a varying magnetic field that induces eddy currents in the workpiece placed within or near the coil. These eddy currents convert to thermal energy due to the resistive properties of the material, rapidly heating the workpiece.
The intelligent control system monitors temperatures in real-time, ensuring uniformity and accuracy in the heating process. An integrated cooling system maintains stable operation of the IGBTs and power supply, preventing overheating. Additionally, the power supply features automated controls and multiple protective measures such as over-temperature and over-current protection, ensuring reliable equipment operation and heating quality.
When selecting an induction heating machine, the choice should be based on the required depth of heating, workpiece size, material properties, and heat treatment process. Here's a summary of the different frequency ranges and their applications:
Low Frequency (Power Frequency): Suitable for deep heating and through-hardening of large and medium-sized workpieces, such as forging and annealing, providing uniform heat penetration.
Medium Frequency: Balances heat penetration and surface heating, ideal for surface hardening and brazing of medium-sized workpieces, offering moderate heating depth.
High Frequency: Used for very shallow surface hardening and tempering, providing rapid and precise heating, suitable for small workpieces or when an extremely thin hardened layer is needed.
Very High Frequency (VHF): Designed for minimal heat-affected zones and high precision heating of very small parts, such as dental and medical instruments.
Ultra-Audio Frequency (UAF): Falls between high frequency and very high frequency, offering fine control over heating and medium depth heating, suitable for precise heating of small to medium-sized workpieces, reducing oxidation and deformation.
Each frequency has its unique applications and advantages. The choice should be based on the specific requirements of the workpiece and the desired heat treatment effects to ensure an efficient and economical production process.
