Abstract

Abstract: As an indispensable raw and auxiliary material in the daily converter front operations,the sintering performance of the hot repair materials determines the quality of hot repair and even the overall service life of the converter,which is of great significance to the development of steelmaking technology.Focusing on the sintering time and sintered strength,the evaluation methods,research progress and existing problems regarding the sintering performance of hot repair materials for converters in recent years were summarized,and the optimization and enhancement techniques for sintering performance were also summarized.As for the current development of steelmaking technology,several key research points that need to be focused on for hot repair materials for converters were put forward in order to provide references for refractory materials and steelmaking technicians.

Key words: hot repair materials for converters, sintering performance, sintering time, sintered strength, performance optimization

摘要： 热态修补料作为转炉炉前日常生产中不可或缺的重要原辅料,其烧结性能的优劣可决定热态修补质量乃至转炉整体使用寿命,对炼钢技术发展具有重要意义。围绕烧结时间和烧结强度两个维度,对近年来转炉热态修补料烧结性能的评价方法、研究进展及存在的一些问题进行了归纳,并对烧结性能的优化提升技术进行了总结。从契合当前炼钢技术发展角度出发,提出了转炉热态修补料需要重点关注的几个研究内容,以期为耐火材料及炼钢技术人员提供参考。
