对济钢中薄板坯连铸机增加浸入式水口壁厚频繁造成粘结的原因行了分析,主要原因是由于流场的不同分布,在水口周围形成死区,影响了传热,并通过数模进行了验证,提出了改进方案。 Analysis of the reasons for increasing the frequent wall thickness of immersed nozzle in Jigang thin slab continuous caster is mainly due to the different distribution of flow field and the formation of dead zone around the nozzle which affects the heat transfer and the number of passing The model was verified and the improvement plan was put forward.
