各类高炉冶炼原料中的碱金属会对高炉冶炼造成严重危害,影响高炉生产效率和稳定性.文章通过探讨碱金属对冶炼原燃料性能、冶炼反应以及炉衬的影响,提出相应碱金属危害防治措施,包括原料控制、工艺控制、添加剂等方法策略.针对碱金属危害,文章提出了炉渣排碱方法作为主要防治手段,分析了各项造渣制度对排碱的影响以及不同条件下排碱的差异性.在生产中,企业需要根据特定高炉情况制定最佳排碱方案,以达到稳定铁水质量、保护高炉等目的.
A Study on Hazard Mitigation of Alkali Metals in Blast Furnace and Alkaline Drainage from Slag
Alkali metals present in diverse raw materials utilized in blast furnace smelting pose a significant threat,imposing severe constraints on the efficiency and stability of blast furnace production.This paper delves into the influence of alkali metals on the fuel performance,smelting reactions,and furnace lining.It proposes corresponding preventive measures against alkali metal hazards,encompassing approaches such as raw material management,process control,and the integration of additives.In response to the challenge posed by alkali metals,this paper advocates alkaline slag disposal as a primary preventive measure,analyzing the impact of various slag-making regimes on alkaline disposal and the nuanced variations in alkaline elimination under differing conditions.In production,enterprises need to make the best discharge plan according to the specific alkaline drainage situation,in order to stabilize the quality of hot metal and protect the alkaline drainage.
