电弧炉炼钢在我国遍及全国各地,各种容量都有,但在生产中却普遍存在由于绝缘不当,引起电极水冷圈与电极相接触而被击穿,被迫停炉再换新水冷圈。这样不但影响连续生产,增加备用水冷圈的费用,同时也给电炉工人在高温下进行更换水冷圈工作带来不必要的 Electric arc furnace steelmaking in our country all over the country, all kinds of capacity have, but in the production but ubiquitous due to improper insulation, causing electrode water cooling coil contact with the electrode was breakdown, was forced to stop the furnace and then replace the new water circle. This will not only affect the continuous production, increase the cost of spare water cooling coil, but also to the electric furnace workers at high temperatures to replace the water ring work unnecessary
