摘要
冶炼钒钛磁铁矿的高炉,由于喷煤时未完全燃烧的煤粉进入炉缸,与高温熔渣接触,促使高熔点的钛的碳氮化合物生成,导致炉渣粘稠,使冶炼无法正常进行,因此喷煤技术被视为冶炼钒钛磁铁矿高炉的禁区。近年来,攀钢高炉采用高冶炼强度、低喷煤强度、均匀喷吹、氧煤混喷等技术改进工艺,使高钛型钒软磁铁矿高炉喷煤技术获得成功,并在攀钢1号高炉投入生产,实现了技术上的重要突破并获得良好的经济效益和社会效益。
The coal injection was not applied to BF working on vanadium bearing titaniferrousmagnetites the reason may be due to the presence of unburnt coal in the hearth during coalinjection and its contact with high temperature slag, titanium-carbidenitride complex of highmelting point is produced. As a result, slag becomes very viscous and normal operation is imp-ossible. Recently coal injection has been tried on No.1 blast furnace at Panzhihua Iron andSteel Co. successfully by hard driving, lowering and smoothing coal injection rate, injectionof oxygen and using other technology. Good economic and social results have been achieved.
