高炉喷吹燃料是六十年代发展起来的降低焦比的一项新技术,我国从1963年开始试验并陆续用于生产。十余年来在应用上有了很大发展,积累了不少实践经验。许多中小高炉也广泛采用了喷吹,如江苏丹阳钢铁厂的13立米小高炉采用喷吹后也取得了明显的效果。为了具体了解高炉喷吹的现状和经验,1976年曾对首钢、鞍钢等十一个大中型炼铁厂进行了调查走访。这些铁厂主要是喷吹重 Blast furnace injection of fuel is developed in the sixties to reduce the coke ratio of a new technology, our country from 1963 began testing and gradually used in production. More than ten years in the application has made great progress, has accumulated a lot of practical experience. Many small and medium-sized blast furnace is also widely used in the injection, such as Jiangsu Danyang Iron and Steel Company 13-m blast furnace with injection also made significant results. In order to understand the status quo and experience of blast furnace injection, in 1976, Shougang, Anshan Iron and Steel and other eleven large and medium-sized iron and steel mills conducted a survey visit. These iron mills mainly blow heavy
