મારે શું કરવું જોઈએ જો મધ્યવર્તી આવર્તન ભઠ્ઠી suddenly loses power

The intermediate frequency electric furnace is powered off, that is, the intermediate frequency power supply has no electricity, and the power supply of the induction coil of the intermediate frequency furnace is also stopped. At this time, the water flow in the induction coil of the intermediate frequency furnace only needs to be 20% to 30% of the normal power supply. In case of a short-term power outage, a high-level water tank should be used as a backup water source. The capacity of the high-level water tank should be considered according to the water consumption during the power outage time of more than 10H. If the power outage time is within 1H, the molten metal surface can be covered with charcoal to prevent heat dissipation and wait for the power to continue. . Generally speaking, no other measures are necessary, and the temperature drop of the molten metal is limited.

If the power outage of the intermediate frequency furnace is too long, the molten metal in the induction coil of the intermediate frequency melting furnace may solidify. The molten metal melted in the intermediate frequency melting furnace will solidify in the crucible, which will hinder the shrinkage of the lining of the intermediate frequency melting furnace, and thus the formation of cracks in the furnace lining will cause the furnace to pass through. Therefore, it is necessary to avoid the molten metal solidification in the crucible. It is best to pour out the molten metal when the molten metal is still fluid.

If there is a power failure during the start of melting of the cold charge of the intermediate frequency furnace, the metal charge has not been completely melted, so it is not necessary to pour it out of the furnace, and it can be kept in its original state. It is only necessary to continue cooling with water and wait for the melting to start when the power is turned on.
