投资2500万元的新喷煤系统于2001年12月30日建成投产,用于2号、3号、5号高炉喷煤,可喷吹烟煤。制粉系统使用球磨机,喷吹系统使用高压并罐直接喷吹的方式,同时采用了多种安全措施和检测手段。在试产阶段和生产初期喷吹无烟煤,2002年2月1日开始配用烟煤(挥发分为14%～17%),随后烟煤比例逐渐加大,3月初,烟煤比例达100%,结束了柳钢只能喷无烟煤的历史。经过半年时间的生产实践,现在已经完全掌握了喷吹烟煤的技术。
The new coal injection system with a total investment of 25 million yuan was put into operation on December 30, 2001 for injection of coal on blast furnaces No. 2, No. 3 and No. 5, and bituminous coal can be injected. Pulverizing system using a ball mill, blowing system using high pressure and direct injection cans, using a variety of safety measures and testing methods. At the trial production stage and early stage of production, anthracite was injected. From the beginning of February 1, 2002, bituminous coal (volatile content of 14% -17%) was used. Then the proportion of bituminous coal gradually increased. In early March, the proportion of bituminous coal reached 100% Liu Gang can only spray anthracite history. After six months of production practice, now has fully mastered the technology of blowing bituminous coal.
