1. No melting before the power failure, need to be prepared.

2. The medium frequency melting furnace is powered off during the melting process. The power failure can be stopped, but the water cannot be stopped. If the power is turned off and the water is stopped, the spare water tank must be opened to cool the furnace. If the power is stopped for a short period of time (less than 10 minutes), you do not need to use the spare water tank, you can wait for the power to continue.

If the power outage time is long, the moisture in the coil and the hose is easy to form a vapor, which affects the cooling effect of the coil and damages the insulation performance of the hose. Therefore, for a long time of water stoppage, the standby water should be connected. The amount of water is generally about 1/4 of the melting flow.

     Within 1 hour of power failure, cover the liquid surface with charcoal to prevent heat dissipation. The power failure time is more than 1 hour. Consider trying to pour out the molten iron.

1. Intermediate frequency melting furnace leakage furnace (leakage liquid)

Leakage accidents can easily cause damage to equipment and even endanger people. Therefore, we should try our best to maintain and maintain the lining in order to avoid leakage.

When the leakage alarm sends a signal, immediately cut off the power supply, inspect the surrounding of the molten iron, check whether the molten iron leaks out, if there is leakage, immediately pour out the molten iron; if there is no leakage, the alarm device should be carefully checked. If it is confirmed that the molten iron and the side electrode are in contact, the molten iron should be poured out immediately.

The leaking furnace alarm can only be used as the reference signal of the leaking furnace. Whether it is really leaking the furnace, but also according to the actual situation of the site, combined with the change of the power in the production record of the melting process, the furnace age of the furnace lining is comprehensively determined.

The thickness of the lining is thinned, the electric efficiency is enhanced, the melting speed is increased, and the material is continuously fed during the production process, and the lining is quenched and heated, causing cracks and leaking the furnace.

Improper tilting, ovens, sintering, or improper lining of the furnace can also cause leaks.
