Common emergency treatment accidents in aluminum melting furnaces

Perlakuan darurat tina suhu cai tiis teuing

(1) The sensor cooling water pipe is blocked by foreign matter, which causes the water flow to decrease and the cooling water temperature is too high. At this time, it is necessary to cut off the power first, and then use compressed air to purge the water pipe to remove foreign objects. It is best not to stop the pump for more than 8 minutes ;

(2) The coil cooling water channel has scale, which causes the water flow to decrease and the cooling water temperature is too high. According to the water quality of the cooling water, the obvious scale on the coil waterway must be pickled in advance every one to two years;

(3) The sensor water pipe suddenly leaks. This water leakage is mostly caused by the insulation breakdown between the inductor and the water-cooled yoke or the surrounding fixed support. When this accident is discovered, the power should be cut off immediately, the insulation treatment of the breakdown area should be strengthened, and the surface of the leakage area should be sealed with epoxy resin or other insulating glue to reduce the voltage for use. Hydrate the aluminum in this furnace and repair the furnace after pouring it. If the coil water channel is broken down in a large area, the gap cannot be temporarily sealed with epoxy resin, etc., so the furnace has to be shut down, the molten aluminum is poured, and repaired.
