由宜兴市芳桥工业炉厂研制的新型耐火可塑料预制电弧炉炉盖,经在无锡县钢铁厂34t电弧炉上使用,获得成功。寿命大于100多炉次。该电弧炉预制炉益直径2500mm,电极圆直径1050mm,电极孔直径500mm,重量3.8t。由于该电弧炉水冷圈经常容易烧坏,漏水影响生产,利用该耐火可塑料预制炉盖, The new refractory plastic prefabricated arc furnace lid developed by Yixing Fangqiao Industrial Furnace Factory was successfully used on the 34t electric arc furnace in Wuxi Iron and Steel Plant. Life expectancy is more than 100 times. The arc furnace prefabricated furnace benefit diameter 2500mm, electrode circle diameter 1050mm, electrode hole diameter 500mm, weight 3.8t. As the electric arc furnace water ring is often easy to burn, water leakage affect the production, the use of the refractory plastic prefabricated lid,
