日本电弧炉炼钢在其钢的总产量中已在不断增加它的分量。主要是通过各种技术进步如采用大型化、超高功率、水冷炉壁、水冷炉盖、富氧、喷碳粉及泡沫渣操作以及电子计算机对输入电力的控制。二次精炼工艺已经普遍采用,不仅特殊钢厂熔炼车间采用,而且联合企业的炼钢车间也在采用。特别是新的钢生产复合工艺包括有电炉炼钢、钢包精炼、RH 脱气和连铸机已被特殊钢厂熔炼车间所采用。电弧炉也在逐步用直接还原铁作为原料不断加入的操作方法,然而这种方法在日本还不普遍。90年代的努力方向是采用比电能更为廉价的能源,促进能源的储存。
Electric arc furnace steelmaking in Japan has been increasing its weight in the total steel production. Mainly through a variety of technological advances such as the use of large-scale, ultra-high power, water-cooled furnace wall, water-cooled furnace cover, oxygen-rich, spray powder and foam slag operation and electronic computer input power control. The secondary refining process has been widely used, not only for the special steel melting plant, but also for the joint-venture steelmaking plant. In particular, the new steel-production compounding process, including EAF, ladle refining, RH degassing and continuous casting machines, has been adopted by special steelworks melting plants. Electric arc furnace is also gradually using direct reduction of iron as raw materials continue to join the operation, but this method is not common in Japan. In the 1990s, efforts were directed at using cheaper sources of energy than electricity to promote energy storage.
