摘要
石家庄钢铁厂高炉从2001年9月开始喷煤,2003年喷煤比达到78kg/t,为进一步提高喷煤量和降低生铁成本,在对原喷吹系统进行改造和完善的基础上,选择了合适的煤种,原燃料质量进一步改善,2004年3月4日开始了烟煤无烟煤混喷实践试验,并取得成功,现烟煤配比稳定在75%以上,达到了节能降耗增效的目的。
Blowing coal process has been used in the blast furnace in Shijiazhuang Steel Work since Sept. 2001 and the rate of blowing coal reached 78 Kg/t iron in 2003. Suitable coal kinds have been selected on the base of further innovating and perfecting the former blowing system for to increase the blowing coal amount and to decrease the cost of pig iron. The fuel quality was improved. The experiment of blowing bituminous and anthracite blending was conducted successfully on Mar. 4 2004. Blending rate of bituminous keeps above 75% steadily. The aim of saving energy, decreasing consumption and increasing efficiency has been reached.
