摘要

摘要: 以水平連鑄圓坯連鑄生產工藝為研究對象,通過射釘實驗并采用Fluent數值模擬軟件建立凝固傳熱模型,研究了在不同工藝條件下圓坯結晶器內的溫度場分布與凝固傳熱過程,并對鑄坯質量進行了相關的檢測分析.通過本研究進一步明確了結晶器內鋼液的溫度場分布,及不同拉坯工藝對結晶器內鋼液溫度場變化的影響.結果表明:通過射釘實驗并采用Fluent數值模擬軟件建立凝固傳熱模型,可以有效分析水平連鑄鋼液的凝固傳熱過程,對改善鋼水質量有積極作用.

Abstract: The temperature distribution and solidification heat transfer process of round billet in different drawing blank technics were studied by means of solidification/melting models of Fluent software and pin shooting jointly, taking round billet horizontal continuous casting process as the research object. By this studies, the liquid steel temperature field distribution in the mold was obtained, and effects of casting process on steel temperature field inside of the mold was achieved. The results show that, through nailing experiment and numerical simulation using Fluent software, the solidification heat transfer model can be established, liquid solidification in continuous casting steel heat transfer process can be effectively analyzed, and the quality of molten steel can be improved.
