Bolt Heating Machine

Expanding bolts with induction is the proven time- and labour-saving alternative to inefficient flame and resistance heating. With induction, a specially designed coil is inserted into the turbine bolt. Rapid, precisely controlled and localized heat is then induced directly in the bolt.Induction heater units incorporate high frequency generators for non-contact heating of metal using electromagnetic induction. When AC is applied to a coil surrounding the work (metal), a magnetic field is generated by the current flowing in the coil, and induced loss (hysteresis loss) is generated causing a heat.Induction heating is also known as high-frequency heating. The induction heating process makes use of currents induced by electromagnetic action in the material to be heated (transformer principle).Heat is transferred to and from objects -- such as you and your home -- through three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows.
