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。
通過分析影響萊鋼闆坯連鑄中間包控流裝置使用壽命的主要問題，開髮與應用瞭以中間包冶金為覈心的控流裝置長壽技術，實踐錶明，應用該技術後，中間包使用壽命達20～28 h，鑄坯中≤20μm的細小夾雜物平均降低51．4％，＞20μm的大型夾雜物基本去除，實現瞭中間包冶金潔淨化、耐材長壽化和生產低成本化。
통과분석영향래강판배련주중간포공류장치사용수명적주요문제，개발여응용료이중간포야금위핵심적공류장치장수기술，실천표명，응용해기술후，중간포사용수명체20～28 h，주배중≤20μm적세소협잡물평균강저51．4％，＞20μm적대형협잡물기본거제，실현료중간포야금길정화、내재장수화화생산저성본화。
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 20~28h, the average numbers of small inclusions sizes less than 20μm reduced by 51.4%, large inclusions sizes larger than 20μm are substantially removed , realizing cleanliness of the tundish metallurgy , refractory longevity and low cost of production .
