The forming of picks requires a series of complex processes, such as diathermy, forging, etc. In the whole heat treatment process, diathermy heat treatment is the most important. Therefore, it is very necessary to choose good diathermy equipment. Now, many manufacturers are using medium-frequency induction heating power supply for diathermy heat treatment on picks, the effect is very good, you can try it if you don’t believe me.
The intermediate frequency induction heating power supply is a cutting-edge high-tech product produced with strict technical requirements based on modern advanced power electronic technology theory, using power electronic devices from more manufacturers in the world, with perfect overvoltage, overcurrent, undervoltage, Water shortage, phase loss, pressure limiting, current limiting and other protection systems ensure the reliability and stability of the equipment. When it performs diathermy heat treatment on the pick, the heating speed is very fast, and several pieces can be heated in one minute. Such a fast heating speed effectively avoids the oxidation and decarburization of the pick during the diathermy process, and ensures the pick’s durability. The diathermy effect makes full preparations for the next forging work.
For picks with a diameter of 40mm, if the processing volume is not large, a 160kw intermediate frequency induction heating power supply can generally be used for diathermy heat treatment. If the processing volume is large, a 200kw intermediate frequency induction heating power supply is required. In fact, not only does the pick need to undergo diathermy heat treatment, it also needs to undergo welding heat treatment. For welding, a 160kw or 200kw intermediate frequency induction heating power supply can also be used, which truly realizes the multi-purpose of the equipment.
