Cooling water accident of medium frequency electric furnace
(1) The high temperature of cooling water is generally caused by the following reasons: the inductor cooling water pipe is blocked and the water flow is reduced. At this time, it is necessary to stop the inductor and blow the pipe with compressed air to remove foreign matters, but it is better to stop the pump for more than 15 minutes. Another reason is that the coil cooling water has scale. According to the quality of cooling water, the coil channel must be set every 1-2 years Acid pickling with hydrochloric acid shall be conducted once, and the hose shall be removed every six months to check the scale. If there is obvious scale blockage on the water channel, acid washing shall be carried out in advance.
(2) The water pipe of inductor suddenly leaks. The reason of water leakage is mostly caused by the insulation breakdown of the inductor to the yoke and fixed bracket. In case of such an accident, the power supply shall be cut off immediately, the treatment of breakdown point shall be strengthened, and the water leakage surface such as epoxy resin or other insulating glue shall be sealed to reduce the use of voltage. Melt the molten iron of the current furnace, and then repair the furnace after pouring. If the coil water channel is broken down in a large area, and the leakage gap cannot be temporarily sealed with epoxy resin, it is necessary to stop the furnace and pour out the molten iron for patching
