The induction furnace whose power frequency is in the range of 150-10000 Hz is called intermediate frequency induction furnace, and its main frequency is in the range of 150-2500 Hz. The power frequencies of domestic small frequency induction furnace are 150, 1000 and 2500 Hz.

At present, induction heating technology has the highest heating efficiency, the fastest speed, low consumption and environmental protection. It has been widely used in hot processing, heat treatment, hot assembly, welding, smelting and other processes of metal materials in all walks of life. It ...

Induction heating equipment can improve the working environment, improve the working environment and corporate image of workers, and have no pollution and low energy consumption. Compared with coal furnace, induction furnace will not be baked and smoked in hot sun, and can meet the requirements o...

1) Fault phenomenon: the equipment cannot be started. During startup, only the DC ammeter has indication, and there is no indication of DC voltage and intermediate frequency voltage analysis a. The inverter trigger pulse is missing b. Inverter thyristor breakdown; c. If signal sampling circui...
