摘　　要：1991年杭钢高炉喷煤系统采用浓相输送技术,从此为界可将喷煤分为两个阶段,第一阶段喷煤量仅为10～30kg/t,第二阶段喷煤量目前已达80kg/t。另外,为了提高喷煤量,还采取了富氧喷吹、提高风温等措施。Technology of dense-phase transport was applied to pulverized coal injection system for BFs at Hangzhou Iron & Steel works,1991.The coal ratio was only 10~30kg/tHM before the technology was applied.At present the coal ratio has reached 80kg/tHM.A series of measures,such as oxygen-enriched blast,high blast temperature,are adopted to raise coal ratio.
