Induction melting furnace will inevitably encounter the problem of sudden power failure during the smelting process, please deal with it according to the following methods. Due to a power outage. When the control circuit and the main circuit are connected to the same power source, the control circuit water pump also stops working. If the water in the induction coil is stopped for more than 3 to 5 minutes, it will cause damage to the coil insulation and cause an accident. Therefore, it is necessary to consider the backup water source and the backup power source in advance when designing the project.

Due to a power failure, the power supply to the induction coil also stops, so at this time the water flow in the induction coil only needs 20% to 30% of the normal power supply. The power failure time is less than 1h. The molten metal surface can be covered with charcoal to prevent heat dissipation and wait for power to continue. Generally speaking, no other measures are necessary, and the temperature drop of the molten metal is limited.

The power failure time of induction melting furnace is too long, and the molten metal may solidify. The solidification of the molten metal in the crucible will hinder the shrinkage of the furnace lining and cause cracks in the furnace lining. Therefore, it is necessary to avoid the solidification of the molten metal in the crucible. It is best to pour the molten metal while it is still fluid. A power outage occurred during the start of the melting of the cold charge, and the charge has not completely melted, so there is no need to pour the furnace out. It can be left in its original state, just continue to pass water and wait for power to start melting again.
