苏联西西伯利亚钢铁厂为了降低高炉焦比,曾先后采用过喷吹煤粉、褐煤焦炭、含有燃料油的水和水油混合剂等方法,但是,经济效果或技术效果并不理想。1978年底,开始采用喷吹天然气技术,经过十几年的不断改进,已取得很大成效。 In order to reduce the coke ratio of the blast furnace, the Western Siberian Iron and Steel Plant of the Soviet Union used the methods of over-blowing pulverized coal, lignite coke, water and oil-water mixture containing fuel oil, etc., but the economic effect or technical effect was not satisfactory. The end of 1978, began to use natural gas injection technology, after more than 10 years of continuous improvement, has achieved great success.
