宁钢2号高炉炉身上部黏结处理

Bonding Treatment for No.2 Blast Furnace Upper Shaft in Ningbosteel

针对宁钢2号高炉由于入炉锌负荷控制不当、边缘气流控制不合理、入炉粉末控制不到位等原因造成炉身上部黏结的现象,通过采取一系列措施,包括降料线处理上部黏结,控制入炉锌负荷、采取合理的上部装料制度、减少入炉粉末、优化冷却制度等,可有效控制炉身上部黏结情况,节约成本。

Due to improper control of zinc load,unreasonable control o f edge gas flow and powder into the furnace,there is upper shaft bonding phenomenon in Nanbosteel No.2 blast furnace.By taking a series of measures,including upper bonding treatment of dropping stockline,control of zinc load,reasonable upper charging system,reducing powder,optimization of cooling system etc.,the upper shaft bonding can be effectively controlled,and the cost is saved.
