摘要
在新钢为降低炼铁成本而实施的"经济炉料"过程中,9号高炉出现了入炉品位下降和渣比上升的现象,通过采取厂内精料工作、加强炉前管理、取消中心加焦、优化下部操作制度、稳定热制度和造渣制度等措施,高炉冶炼获得了较好的经济技术指标。
The phenomenon of low grade charging and high slag ratio appear in No. 9 blast furnace when ＂Economic burden＂ is implemented to reduce the cost of ironmaking in Xinyu Steel. Better economic and technical indicators are obtained by adopting meas- ures such as： fine material, strengthen management, cancel central coke charging, optimize the operating system at bottom, stable ther- mal system and slag making system.
