摘要
针对萍乡钢铁公司高炉炼铁燃料比高的现状,从原料冶金性能与粒度组成、炉料结构、合理冶炼强度、造渣制度、多环布料、适宜煤粉喷吹量、低硅生铁冶炼等方面,分析了降低高炉燃料比的技术措施。研究表明:改善焦炭质量,加强筛分与整粒,选择适宜冶炼强度,选择适宜MgO的渣系,缩小加权平均角差,避免过度中心加焦,根据原燃料条件选择煤比,稳定生铁的含硅量是降低高炉燃料比的关键技术措施。
In view of ironmaking fuel ratio of blast furnace in PingGang, discussed the technical measures of reducing fuel ratio from various aspects of raw materials metallurgical properties, grain composition, burden design, reasonable smelting intensity, slagging regime, multi-circle burden distribution, appropriate for coal powder, smelting low silicon Iron and so on. The study shows that the key technical measures to lowering the fuel rate are improving the quality of coke, further screening and size stabilization, choosing the suitable smelting strength and appropriate MgO slag system, narrow- ing weighted average angle difference, avoiding excessive center coke charging, choosing coal ratio according to the raw material and fuel conditions and stabilizing silicon content of pig iron
