摘要
深入探讨了高炉中锌的危害以及提高高炉排锌率的多种措施.锌在高炉内的循环和积累会对煤气利用、焦炭质量、炉衬结构和炉料性能等方面产生诸多不利影响.通过对锌排出途径的分析,提出了从原料控制、高炉操作制度改进、炉渣管理、出铁次数调整、煤气灰处理以及监测与分析等一系列综合措施,旨在减少锌在高炉内的富集,提高高炉的生产效率和寿命,为钢铁企业的高炉炼铁生产提供有益的参考和指导.
Abstract
This article deeply explores the hazards of zinc in blast furnaces and various measures to improve the zinc removal rate of blast furnaces.The circulation and accumulation of zinc in blast furnaces can have many adverse effects on gas utilization,coke quality,lining structure,and charge performance.Through the analysis of zinc discharge pathways,a series of comprehensive measures have been proposed,including raw material control,improvement of blast furnace operation system,slag management,adjustment of iron tapping frequency,gas ash treatment,and monitoring and analysis.The aim is to reduce the enrichment of zinc in the blast furnace,improve its production efficiency and lifespan,and provide useful reference and guidance for steel enterprises'blast furnace iron-making production.
