炼钢厂中间包使用寿命突破120小时实践

Practice on the Service Life of Tundish Exceeding 120 Hours in Steelmaking Plant

文中主要介绍了某单位炼钢厂连铸中间包连续使用突破120小时创下最高使用寿命纪录的生产实践,在提高中间包使用寿命攻关活动中,各相关单位通过采取一系列技术措施,于2020年12月9日23:47时,1^(#)连铸机6^(#)中间包创下了中间包使用寿命的历史新高纪录——123小时17分钟。通过总结该中间包创纪录的成功经验,分析当前影响中间包使用寿命的因素,以采取有效措施,具备了推广使用的条件,为下一步普遍提高炼钢厂中间包的平均使用寿命奠定基础。

This paper mainly introduces the production practice of continuous casting tundish in a steelmaking plant,which has exceeded 120 hours and set a record of the highest service life.In the key research activities to improve the service life of tundish,all relevant units took a series of technical measures,and at 23:47 on December 9,2020,1^(#)continuous caster 6^(#)tundish has set a new record for the service life of tundish-123 hours and 17 minutes.By summarizing the record successful experience of the tundish and analyzing the current factors affecting the service life of the tundish,effective measures are taken to meet the conditions for popularization and use,so as to lay a foundation for generally improving the average service life of the tundish in the steelmaking plant in the next step.
