Treatment Method of Cooling Water Accident in Metal Melting Furnace

(1) Excessive cooling water temperature is generally caused by the following reasons: the sensor cooling water pipe is blocked by foreign matter, and the water flow rate is reduced. At this time, it is necessary to cut off the power and blow the water pipe with compressed air to remove foreign objects. It is best not to stop the pump for more than 15 minutes. Another reason is that the coil cooling water channel has scale. According to the cooling water quality, the coil water channel must be blocked with obvious scale every 1 to 2 years, and it needs to be pickled in advance.

(2) The sensor water pipe suddenly leaks. The cause of water leakage is mostly caused by the insulation breakdown of the inductor to the water yoke or the surrounding fixed support. When this accident is discovered, the power should be cut off immediately, the insulation treatment at the breakdown site should be strengthened, and the surface of the leaking site should be sealed with epoxy resin or other insulating glue to reduce the voltage for use. The hot metal in this furnace should be hydrated, and the furnace can be repaired after it is poured. If the coil channel is broken down in a large area and the gap cannot be temporarily sealed with epoxy resin, the furnace has to be shut down, molten iron is poured, and repaired.
