苏联过去一向以平炉为中心发展炼钢生产,1960年苏联平炉钢产量占总钢产量的84.4％。尽管苏联早在1962年就决定发展氧气转炉生产,但发展速度非常缓慢,至1967年苏联钢产量突破1亿 t 大关时,平炉钢比重仍占80％。直到现在,苏联仍有200～900t 平炉300多座,平炉钢仍占总钢产量的54％左右。从50年代后期开始,世界其他国家广泛而迅速地发展氧气转炉生产。目前世界
In the past, the Soviet Union had always taken the hearth as the center to develop steelmaking production. In 1960, the open hearth steel output of the Soviet Union accounted for 84.4% of the total steel output. Although the Soviets decided as early as 1962 on the development of oxygen converter production, the pace of development was very slow. By 1967, when the Soviet Union’s steel output exceeded the 100 millionth mark, the proportion of open hearth furnaces still accounted for 80%. Until now, the Soviet Union still has more than 300 open-hearth furnaces of 200-900 tons, with open hearth steel still accounting for about 54% of total steel output. Since the late 1950s, oxygen converter production has been extensively and rapidly developed in the rest of the world. The world
