A bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten and connect two parts with through holes. The forming of bolts requires a series of complicated processes, the most important of which is diathermy heat treatment. Bolt diathermy is usually completed by medium frequency induction heating machine, and the effect is very good.
The medium frequency induction heating machine has high efficiency and obvious power saving. It saves 60% power compared with traditional equipment and 20% power saving compared with thyristor medium frequency. When the bolt is subjected to diathermy heat treatment, the heating speed is very fast, which effectively avoids the phenomenon of oxidation and decarburization of the bolt during the heating process, and ensures the heating effect of the bolt. Even better, the medium frequency induction heating machine can not only perform diathermy heat treatment on the entire bolt, but also heat a certain part of the bolt, which can meet the processing requirements of different customers.
The induction coil of the medium frequency induction heating machine can be replaced freely, which enables the equipment to complete heat treatment processes such as quenching, annealing, tempering, normalizing, and tempering, as well as welding, smelting, thermal assembly, and thermal disassembly. One machine with multiple functions realizes the equipment.
