摘　　要：碱金属在高炉内的循环富集对高炉生产的危害极大,通过调整反应温度、碱度、MgO和Al_(2)O_(3)等参数,研究高炉排钾效果的影响因素,并进行原因分析。研究结果表明:反应温度、炉渣碱度、MgO含量升高,炉渣排钾能力下降,而炉渣中Al_(2)O_(3)含量增加,炉渣排钾能力提高。The cyclic enrichment of alkali metals in blast furnaces poses a great threat to blast furnace production.By adjusting parameters such as reaction temperature,alkalinity,MgO,and Al_(2)O_(3),the influencing factors of potassium removal efficiency in blast furnaces are studied,and the reasons are analyzed.The research results indicate that as the reaction temperature,slag alkalinity,and MgO content increase,the slag’s ability to remove potassium decreases,while as the Al_(2)O_(3) content in the slag increases,the slag’s ability to remove potassium improves.
