摘　　要：结合活动烟罩和空气过剩系数因素,分析了转炉汽化冷却烟道的安全设计问题和安全运行要素。结合对烟道结构和空气过剩系数的分析,分别针对80,120,180,210 t转炉进行传热分析,结合计算结果,得出转炉出口温度变化规律,并进行了综合性对比分析。分析结果表明,选择合理结构和合适的空气过剩系数是转炉汽化冷却烟道在设计、生产过程中至关重要的因素,是预防转炉安全生产事故发生的关键。In this paper,the safety design&operating factors of convertor waste hear boiler were analyzed by combining the active cover&air excess coefficient.Combined with the analysis of flue structure and air excess coefficient,heat transfer analysis was carried out for converter of 80 tons,120 tons,180 tons and 210 tons respectively,and based on the calculation results,the temperature change rule of converter outlet was obtained and a comprehensive comparative analysis was made.The analysis results show that the selection of a reasonable structure and the appropriate excess air coefficient are the most important factors in the design and production of the converter waste heat flue,and the key to prevent the occurrence of converter safety accidents.
