国家机械委于87年7月授予大连起重机厂5t电弧炉为我国机械工业系统首台节能型特等炉称号。几年来,大连起重机厂采用各种技术措施,对该炉进行了三次大的技术改造并实行了严格的科学管理。获得了很好的节能效果,吨钢单位电耗,1983年为592度,1986年下降到514度,1987年上半年又达到511度。在我国机械工业系统上万个企业的约4万台电炉中,第一个跨入世界先进炉的行列。如果总结推广其经验,使全国电炉的吨钢电耗均达到该炉的水
State Machinery Commission in July 87 awarded Dalian cradle 5t electric arc furnace for China’s machinery industry system, the first energy-saving special furnace title. Over the past few years, Dalian Crane Factory adopted a variety of technical measures, the furnace was three major technological transformation and the implementation of a strict scientific management. A good energy-saving effect has been achieved, power consumption per tonne of steel, 592 degrees in 1983, down to 514 degrees in 1986, the first half of 1987 and reached 511 degrees. Among the 40,000 electric furnaces of 10,000 enterprises in China’s machinery industry system, the first one has stepped into the ranks of advanced furnaces in the world. If we summarize and popularize its experience, the electricity consumption per tonne of steel in the whole country will reach the water of the stove
