济钢集团高炉喷吹系统采用三个喷吹罐并列布置上料,喷吹主管加炉前分配器的喷吹形式,通过对喷煤工艺的改进和操作优化,彻底解决了喷吹启动困难问题,减小了喷吹脉动现象,装煤速度快,喷煤保障性高,喷吹能力大,满足了高炉喷煤量的要求,最大喷煤比已达170kg/t以上。它的成功应用为高炉生产稳定,增产降焦提供了良好条件,降低了成本,实现了节能降耗。 Jining Iron and Steel Group blast furnace injection system using three jets arranged side by side on the material, the injection pipe charge plus the former distributor of the injection form, through the coal injection process improvement and optimization of operation, completely solve the problem of injection start difficult , Reducing the pulsation phenomenon of pulverized coal injection, fast coal charging, high coal injection protection, large injection capacity, which meets the requirement of blast furnace coal injection. The maximum coal injection rate has reached more than 170kg / t. Its successful application provides a good condition for blast furnace production stability, increase production and reduce the coke, reduces the cost, has realized the energy conservation to reduce the consumption.
