摘　　要：碱金属元素的存在加剧了转底炉设备管道系统的堵塞风险以及炉衬结构的腐蚀程度,不仅威胁到生产流程的持续稳定性,还影响转底炉最终产品的品质。本文系统剖析了碱金属的来源构成及其物理化学特性,深入探讨了碱金属在转底炉内的迁移转化行为和其与设备内壁发生黏结反应的内在机制,并从入炉原料预处理策略、设备工艺优化设计、产物回收与处理等多维度综合考虑,归纳并提出了一系列旨在有效减轻碱金属危害的实用措施,以期为转底炉工艺的优化升级与稳定运行提供科学依据与实践指导。The presence of alkali metal elements exacerbates the blockage risk of the piping system of the rotary hearth furnace equipment and the corrosion degree of the furnace lining structure,which not only threatens the continuous stability of the production process,but also affects the quality of the final product of the rotary hearth furnace.In this paper,the source composition and physicochemical properties of alkali metals are systematically analyzed.The migration and transformation behavior of alkali metals in the rotary hearth furnace and the internal mechanism of the bonding reaction between alkali metals and the inner wall of the equipment are deeply discussed;the pretreatment strategy of raw materials in the furnace,the optimization design of equipment process,and the recycling and treatment of products are multi-dimensionally and comprehensively considered,and a series of practical measures to effectively reduce the hazards of alkali metals are summarized and proposed,in order to provide scientific basis and practical guidance for the optimization,upgrading and stable operation of rotary hearth furnace process.
