Induction melting furnace power failure accident plan, for the safety of life, must be seen!

When the induction melting furnace encounters a power outage accident, the furnace cannot work normally. First of all, ensure that the furnace body cannot be cut off and protect the coil from damage. Therefore, the following options are available.

1. If the water pump in the clean water pump room works normally, adjust the water pump to balance the upper and lower water levels to ensure that the large and small wells do not overflow, and the small wells do not lack water.

2. If the clean water pump fails to work normally, use the accident valve to supply water to the furnace body. After opening the accident valve, close the water pump valve to ensure that the water level of the large well does not drop.

3. Emergency plan:

1). If there are signs of furnace leakage or furnace leakage, and the leakage point is high, the power supply must be cut off immediately, the cooling water must not be shut off, and the furnace must be discharged urgently. After the molten iron is finished, check the position of the furnace.

2) If there are obvious signs of furnace wear and large leakage, which can cause serious damage to the equipment, to reduce the equipment loss to a minimum, turn off the power immediately, turn the molten iron into the furnace pit, and cover it with dry sand to prevent it from being damaged. Furnace body.

3) In the event of an emergency furnace leakage or accident, personal safety should be protected first, and equipment safety secondly, the furnace body should mainly protect the induction coil first; therefore, it is forbidden to shut down the cooling water, and finally protect other parts to minimize the loss. degree.

4). If there is a wear or leakage accident or there are signs of wear or leakage, if the power supply does not stop, the power supply should be cut off to protect the thyristor inverter tube and the rectifier tube.
