Furnace ring induction coil failure of intermediate frequency furnace

The induction coil is the load of the intermediate frequency power supply and is also a furnace ring. It is made of a square copper tube with a wall thickness of 3 to 5 mm. Its common faults are as follows: the induction coil leaks, which may cause the coil to ignite between the turns, and must be repaired in time to run. The molten steel sticks to the induction coil, and the steel slag is hot and red, which will cause the copper tube to burn through and must be cleaned up in time. Induction coils are short-circuited between turns, and such faults are particularly prone to occur in small-medium-frequency induction heating furnaces because the furnace is small, subjected to thermal stress during operation or deformed during furnace, resulting in a short circuit between turns, and the fault is characterized by a large current. The frequency is higher than usual. Sometimes it is difficult to start. Check the troubleshooting carefully.
