高炉喷吹煤粉在我国已有二十余年的历史,现在已成为我国高炉大幅度降低焦比的一项重要技术措施。 早在1963年我院就开始了喷吹煤粉的实验室工作。1964～1966年间与首钢协作在该厂进行高炉喷吹无烟煤工业性试验,获得成功。当时首钢1~#高炉正式投入生产,取得良好的效果,喷吹量最大曾达到319公斤/吨铁,置换比约为0.8。不久,这一技术推广到其 Pulverized coal injection blast furnace in our country has more than 20 years of history, has now become China’s blast furnace significantly reduce coke ratio is an important technical measure. As early as 1963, our hospital began the pulverized coal injection laboratory work. 1964-1966 years with the Shougang blast furnace in the anthracite coal injection blast furnace industrial test success. At that time Shougang 1 # blast furnace officially put into production, achieved good results, the largest blowing amount has reached 319 kg / ton of iron, the replacement ratio of about 0.8. Soon, this technology is extended to it
