How to deal with a large area of molten iron in induction melting furnace?

Large-area molten iron leakage occurs in the induction melting furnace, and the load current of the furnace rises rapidly. If the current value exceeds the protection current value, the induction melting furnace will automatically shut down to protect the equipment components from damage. After the furnace is repaired, it can operate as usual. If molten iron leaks from the cracks in the furnace lining, it causes a local induction coil, and does not cause a short circuit between the induction coils or local ignition. The load current does not exceed the equipment current protection value and the equipment cannot be shut down, which is a normal phenomenon. Therefore, the user should always check whether the rated current protection value of the equipment is working properly. The alarm signal set by the lining thickness detection device can also be linked to the shutdown of the variable frequency power supply device, and the size of the alarm signal is carefully determined by the user. Because the signal is too large, it is easy to cause the induction melting furnace to malfunction, the signal is too small, and the action is not sensitive. The above two methods can make the frequency conversion power supply stop during work, but the principle of the shutdown is different. You need to treat it separately and find the reason. , Can’t be confused.
