进入50年代以来,苏联炼铁生产高速度稳步向前发展,产量逐年上升。1970年生铁产量达8593万 t,超过美国,居世界第一位,1975年突破1亿 t 大关,1984年生铁产量为11089万 t。苏联发展炼铁生产的主要途径是:推行高炉大型化,不断改进设备结构和性能,新建大型高炉和扩容改造中小高炉;加强炉料准备,采用高风温,喷吹补充燃
Since the 1950s, the Soviet Union’s iron-making production has been steadily moving forward at a high speed and output has been increasing year by year. Pig iron production in 1970 reached 85.93 million tons, surpassing the United States, ranking first in the world. In 1975, it exceeded 100 million tons. In 1984, the output of pig iron was 110.89 million tons. The Soviet Union to develop the main ways of iron production are: the implementation of large-scale blast furnace, and constantly improve the structure and properties of equipment, new large blast furnace and expansion of small and medium-sized blast furnace; strengthen charge preparation, the use of high winds,
