| 摘 要： | 建立了卧式离心铸造情况下液体充型及凝固过程的数学模型.基于该模型对卧式离心铸造轧辊离心阶段的温度场、流场进行了数值模拟.采用水力学模拟试验与数值模拟进行对比，结果表明数学模型准确可靠.通过对卧式离心铸造充型过程中金属液运动规律的分析，发现卧式离心情况下金属液按螺旋形轨迹充填型腔.随着转速的增加，金属液更易于均匀铺满型腔.这对采用卧式离心铸造轧辊的实际生产具有一定的指导作用.关键词：卧式离心铸造数学模型数值模拟水力学试验

| Abstract: | A mathematic model of mold filling and solidification in horizontal centrifugal casting is built up. Based on this model, the temperature field and the flow field in horizontal centrifugal casting are numerically simulated. The hydraulic experimental results are compared with numerical simulations, indicating that the mathematic model is accurate. Experimental results show that liquid fills the mold in the manner of a spiral trajectory in the centrifugal casting process. The filling pattern tends to be more uniform with the increase of rotational speed. The present study has a guiding significance to the production of horizontal centrifugal casting roll. |
