The purpose of induction bolt heating to heat and expand bolt, making it easy to remove the nuts. Induction bolt heating process is mainly used in power stations, chemical plants and oil and gas processing plants, such as high temperature cylinder bolts, high pressure bolts, steam guide pipes, extraction pipes, regulating flange bolts and so on.

Induction heating of bolts and nuts is a fast and effective way in heat treatment process. This method is easy to operate and suitable for remove or installation of various metal parts, such as driving parts, bearings, bearing blocks, gears, bolts, nuts, pipe fittings and small parts, etc. Induction heating can quickly heat the local parts of the bolt and nut. After the bolt is preheated, it will expand and lengthen, and the nut will be easily removed. Due to the heat is generated inside the bolts, and the heating delivery is very quick, heat energy does not enter the threaded area, thus reducing the bolt damage rate.
How to select induction bolt heating system?
ROCHO portable induction heating equipment, using the latest IGBT solid-state circuit design, has a very compact design and high energy output, equipped with a remote hand-held transformer working head for precise local heating of fasteners. Up to 30 meters, the cable is flexible and easy to move, suitable for local heating of narrow Spaces. ROCHO induction heating technology can heat different parts without changing the frequency conversion power supply. According to the different material and size of the product, only different heating rods need to be replaced.
Benefits of induction bolt heating system.
Compared with the surface hardening heated by fire, the induction hardening heat is generated in the workpiece itself, so the energy consumption is small and the thermal efficiency is high. The hardened metal undergoes martensite transformation, which increases the hardness and wear resistance of the workpiece. Fast heating and cooling, less workpiece deformation, less oxidation and decarburization, no further mechanical processing after hardening, thus saving processing costs; high production efficiency, convenient to realize mechanized and automatic mass production; no waste gas and less environmental pollution.
