随着机械工业的飞速发展,可控硅中频感应熔炼炉的应用越采越广泛。我厂先后在西安变压器电炉厂购置了两套可控硅中频熔炼设备,至今已熔炼了上万炉钢水,对我厂生产的发展起了很大的作用。可是在熔炼中,有时会发生突然停电事故,使熔融的钢液冻结在炉中,待排除故障再熔炼时,已无法起机了。最初每逢这种情况,只好将炉衬打掉取出冷钢,再重新打结炉衬进行熔炼,这既影响了生产又增加了消耗。特别是最初对可控硅熔炼设备使用和维修经验不足,在熔炼中常发生电器故障,又
With the rapid development of machinery industry, silicon controlled induction melting furnace more and more widely used. I plant in Xi’an Electric Furnace transformer plant purchased two sets of silicon controlled frequency melting equipment, has so far been melted on the furnace of molten steel, the development of our plant played a big role. However, in the smelting, sometimes a sudden power failure will occur, the molten steel frozen in the furnace, to be solved when the fault remelting, it has been unable to take off. For the first time in each case, the lining had to be knocked out to remove the cold steel and the knot was re-knotted for melting, which not only affected the production but also increased the consumption. In particular, the initial lack of experience in the use and maintenance of SCR melting equipment, electrical failures often occur in the melting, and
