“七五”期间,抚顺钢铁公司炼铁厂在生产中积极采用新工艺、新技术,在高炉大修中针对生产中存在的主要问题进行了改造,对炼铁生产起到了促进作用。1.炉缸喷吹压缩空气炉缸工作是高炉冶炼的重要一环。向炉缸喷吹压缩空气可以直接向炉缸工作施加影响,由于氧化性气体的喷入,可以改变非铁元素的还原状况。还可以通过炉缸下部焦炭的燃烧,加速炉芯呆滞区域焦炭的更新,松动中心料柱,有利活跃炉缸,也有利于消除焦炭,粉末造成的炉缸堆积。这项试验是从1987年8月12日开始在1
During the “Seventh Five-Year Plan” period, the Fushun Iron and Steel Company iron and steel mill actively adopted new techniques and technologies in its production. In the process of overhauling the blast furnace, the major problems in its production were transformed to promote the production of iron-making. 1. The hearth blast furnace compressed air blast furnace is an important part of blast furnace smelting. The injection of compressed air into the hearth can exert an influence directly on the operation of the hearth. Due to the injection of oxidizing gas, the reduction of non-ferrous elements can be changed. But also through the lower part of the hearth coke combustion to accelerate the core area of the coking furnace dull renewal, loosening the center column, the active hearth cylinder, but also help to eliminate coke, powder accumulation caused by the hearth. This test was started on August 12, 1987
