1我国的电炉钢发展为什么背离世界潮流电炉机厂主要以废钢作原料，故比传统的高炉、转炉组成的联合企业生产流程短，从而使造价低40％～50％，能耗低30％，成本低10％左右。故自80年代以来，电炉比一直呈上升趋势，特别是从1989年美国纽柯公司采用薄板坯连铸连轧生产薄板卷的工 1 Why the development of China’s electric furnace steel Deviation from the world trend Electric furnace factory mainly scrap as raw material, so the traditional blast furnace converter composed of the joint venture production process is short, so that the cost of 40% to 50% lower, 30% lower energy consumption, Low cost about 10%. Therefore, since the 1980s, the EAF has been on an upward trend, especially from the United States in 1989 Nucor used thin slab continuous casting and rolling production of sheet metal workers
