| 摘 要： | 为了满足薄板坯连铸工艺高拉速对结晶器流场和温度场的要求,对浸入式水口的结构进行了研究。通过数值模拟研究,对薄板坯连铸浸入式水口进行了优化,优化后的新型浸入式水口可以获得高拉速状况下稳定的结晶器流场和温度场。同时对新型浸入式水口进行了水模分析,验证了数值模拟结果的有效性。现场试验新型浸入式水口,发现结晶器液面平稳、热相图稳定,板卷质量良好,铸机拉速较原水口提高22%。

| Abstract: | In order to meet the requirement of high casting speed of thin slab casting process with regard to mould flow field and temperature field, the structure of SEN of thin slab caster was studied. The optimization of SEN was studied based on mathematical model analysis to obtaining high casting speed, the new type SEN can provide the stabilize flow field and temperature field in the mould. Water model was also builded and analysed at the same time, the same conclusion was obtained. The new type SEN was tested on site, the mould level was steady, the thermo-map was stable, the quality of coil was good, and the speed of caster increase 22%. |
