近几年来日本电炉钢在总钢产量中的比例稳步缓慢上升,1982年达2653万吨,占27.5％,比上年度增加2.6％,而10年来电耗却逐步下降,从73年吨钢耗电579.8度(100％)降至82年的509.9度(87.9％)。主要对策如下: 1.改善操作。利用自身废热预热废钢,可降低电耗30—40度/吨钢,电极单耗下降0.3—0.5公斤/吨钢,缩短化料时间3—4％, In recent years, the proportion of Japan’s EAF steel in total steel output has steadily and slowly risen to 26.53 million tons in 1982, accounting for 27.5%, an increase of 2.6% over the previous year, while the electricity consumption in the past 10 years has been gradually decreasing. From 73 tons of steel consumption Electricity dropped from 579.8 degrees (100%) to 509.9 degrees (87.9%) in 1982. The main countermeasures are as follows: 1. Improve the operation. Using its own waste heat preheating scrap, can reduce power consumption 30-40 degrees / ton of steel, the electrode unit consumption decreased 0.3-0.5 kg / ton of steel, shorten the time 3-4%
