HGM—0.5吨三相电弧炉的炉龄,一般在80～200炉之间。我厂的HGM—0.5吨炼钢炉的炉龄,近几年均在1000炉左右,现在又突破了2000炉的大关。这次是1982年2月大修投产的,到1983年12月底止,共炼钢2019炉,钢水产量1615t。仅1983年就炼钢1175炉,钢水产量954t。由于炉龄的提高,我厂1983年铸钢的生产效率、钢水质量及各项技术经济指标,均有明显的提高,获得了较好的经济效益。为了提高炉龄,我们主要采取了以下措施。
HGM-0.5 tons of three-phase electric arc furnace, usually between 80 ~ 200 furnaces. The furnace age of our HGM-0.5t steel-making furnace has been around 1000 in recent years, and now it has exceeded the mark of 2000 furnaces. This is the overhaul production in February 1982, until the end of December 1983, a total of 2019 furnace steelmaking, steel production 1615t. In 1983 only 1175 furnace steelmaking, steel production 954t. Due to the improvement of furnace age, the production efficiency, the quality of molten steel and various technical and economic indexes of our steel mills in 1983 have been significantly improved and better economic benefits have been obtained. In order to improve the furnace, we mainly take the following measures.
