Heating large bolts first, then assembling them and waiting for them to cool down to achieve the purpose of fastening is a common method for assembling large structural parts; while in disassembly, the bolts are also heated first to expand and become longer to achieve the purpose of disassembly.
Compared to the electric wire heating method or flame heating method, the induction heating method has many advantages:
● Fast speed and substantial savings in disassembly time;
● Automatic temperature control, preventing overheating, annealing and material denaturation of the bolt;
long life of induction heating rods and equipment;
-No wearing parts and lower running costs.
For the thermal expansion of bolts, our factory has developed special induction heating equipment that includes power supplies, inductors, and even connection components and installation methods that take into account the special hygiene techniques of bolt thermal expansion and the need for fast on-site operation.
>Unlike the electric wire heating method, the heat from induction heating directly on the bolt is highly efficient and fast, 5-10 times faster than the electric wire.5-10 times faster than the electric wire method, resulting in a significant increase in productivity. Bastick Electric 5.The problem of easy annealing and denaturation of the bolt is solved completely.Automatic control of the bolt temperature ensures that the bolts are not overheated.1-8 independent output units, each output unit is
independent power regulation and temperature control is possible.
>The insulation resistance of the inductor or extension cable is detected and protected online.protection, which is a guarantee of personal safety in complex applications on site.The protection is a guarantee of personal safety in complex field applications.​​
