We need to remove the bearing inner ring and coupling by heating. How many types of flexible coil medium frequency induction heaters do you have? Give a detailed introduction, easy to buy.
Manufacturer's reply
The principle of the flexible coil induction heater is the electromagnetic winding heating method, which winds the high temperature electromagnetic wire around the outside of the workpiece to heat, and because the high temperature electromagnetic wire is a soft wire with flexibility, it is said to be a flexible coil heater.
The whole set of flexible coil induction heating equipment is composed of medium frequency heating host and high temperature electromagnetic wire, assisted by asbestos cloth and temperature resistant gloves. The key part is the electromagnetic heater host, which is actually a medium and high frequency heating power supply, and the key components are the full bridge, IGBT module, filter capacitor and multiple motherboards.Flexible coil heater - coil heating device.jpgCoil induction heater.jpgFlexible coil is wound to the workpiece outside the electromagnetic heating wire, electromagnetic wire cover there are two main common: one is the silicone wire, the outside of the silicone skin has dark red, black or green, etc., the general temperature resistance of the silicone wire is only 180 ° C, over temperature may melt the silicone skin. Many people like this kind of foreskin, but the temperature resistance has limitations.
There is also a kind of outside looks white, called high temperature mica wire, this line is made of glass wire and other materials, can withstand 500 ° C, due to high temperature resistance and is commonly used.
Flexible coil medium frequency induction heater specification model table
name | class | parameter | remark |
Flexible coil heating machine | Power size | 30、40、60、80、120KW | according to the size of the workpiece |

Regardless of the kind of sheath of the flexible coil, the core is the same, to fully consider the temperature of the heating workpiece, and whether it is used continuously for a long time, whether it will overtemperature heating and other factors, choose the appropriate high temperature line, the heating process is found to be damaged in time, can not let the bare core touch the metal, otherwise it will burn the induction heater.
