根据立式双辊铸轧机设备实际条件,设计出一套镁合金铸轧布流系统,利用Anycasting?软件对布流系统内的流动状态和温度分布进行了数值模拟;同时根据相似理论制作出一套与实际系统比例为1∶1的有机玻璃模型,用以进行物理模拟。结果表明,多级以及中间带有挡坝的布流系统不但可降低流股对熔池液面的冲击,还可以获得均匀的流场,挡坝的最优化高度为10mm,并优化了挡坝位置,确定了布流系统出口处的宽度。当宽度为1mm时可获得稳定且温度分布均匀的熔池。
According to the actual equipment of vertical twin-roll casting and rolling mill, a set of magnesium alloy casting and rolling distribution system was designed. Anycasting software was used to simulate the flow distribution and temperature distribution in the distribution system. At the same time, Set and the actual system ratio of 1: 1 plexiglass model for physical simulation. The results show that the multi-stage and middle dam system can not only reduce the impact of the flow on the bath surface, but also obtain a uniform flow field. The optimum height of the dam is 10 mm and the dams are optimized Position, to determine the width of the distribution system exit. When the width of 1mm can be obtained stable and uniform temperature distribution of molten pool.
