摘　　要：莱钢1880m3高炉喷煤系统包括制粉与喷吹两大子系统,原煤经破碎机破碎后形成粒煤再由喷吹系统送入2座1880m3高炉,其中粒煤破碎引进德国破碎机工艺,喷吹系统引进英国克莱德工艺。该系统较之传统粉煤技术降低成本效果显著,且稳定炉况,提高生铁质量。Laiwu Steel 1 880 m3 blast furnace GCI system consists of the milling and the injection two major subsystems,the raw coal after the breaker stave forms the granular coal was fed into two 1 880 m3 blast furnaces by the injection system,the coal crusher technology introduced the German breaker craft,GCI system introduced England Clyde process. Compared with traditional PCI technology,this system reduced the cost observably,stabilized the furnac conditions and improved the quatily of pig iron.
