英刊《金属通报》一九八一年十二月三十日报道:据国际钢铁协会的一份报告称,八十年代世界电炉炼钢的进步将主要表现在三个方面:提高生产能力;降低生产费用和提高热效率。发展中国家拥有的天然气可以用于电炉和直接还原炉。该报告指出,世界电炉钢在钢总产量中的比例已在稳步增长,从1960年的11％增至1978年的19.6％, According to a report by the International Iron and Steel Institute, the progress of the world’s EAF in the 1980s will be mainly manifested in three aspects: increasing production capacity; Reduce production costs and improve thermal efficiency. Natural gas owned by developing countries can be used in electric furnaces and direct reduction furnaces. The report pointed out that the world’s EAF steel production in the proportion of steel has been steadily increasing from 11% in 1960 to 19.6% in 1978,
