中频电炉冷却水事故
Cooling water accident of medium frequency electric furnace
(1)冷却水温度过高一般由下列原因产生:感应器冷却水水管有导物堵塞,水的流量减小,这时需要停,并用压缩空气吹水管除去异物,但停水泵时间最好不要超过15分钟;另一个原因是线圈冷却水水渞家水垢,根据冷却水水质的情况,必须每隔1---2年把线圈水道用盐酸酸洗一次,每隔半年取下软管检查水垢情况,如在水道上有明显的水垢堵塞,需要提前进行酸洗。
(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)感应器水管突然漏水。漏水原因多是感应器对磁轭和固定支架绝缘击穿所形成的。当发生此事故时,立即停电,加强击穿处的绝处理,并用环氧树脂或其他绝缘胶等漏水表面封住,降低电压使用。把当前炉铁液熔炼好,倒完后再进行炉子维修,若线圈水道大面积被击穿,无法用环氧树脂等临时封补漏水缺口,只得停炉倒完铁水进行仆补
(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
