摘　　要：通过分析影响莱钢板坯连铸中间包控流装置使用寿命的主要问题,开发与应用了以中间包冶金为核心的控流装置长寿技术,实践表明,应用该技术后,中间包使用寿命达20~28 h,铸坯中≤20μm的细小夹杂物平均降低51.4%,〉20μm的大型夹杂物基本去除,实现了中间包冶金洁净化、耐材长寿化和生产低成本化。By analyzing the main problems affecting the service life of slab continuous casting tundish flow control devices in Laiwu Steel,flow control devices longevity technology with intermediate package metallurgical as the core were developed and applied. Practice shows that after the application of the technology,the service life of the tundish reach up to 20 ~ 28 h,the average numbers of small inclusions sizes less than 20 μm reduced by 51. 4%,large inclusions sizes larger than 20 μm are substantially removed,realizing cleanliness of the tundish metallurgy,refractory longevity and low cost of production.
