摘　　要：在浇注系统的结构设计中,坩埚设计成两个腔体,两个腔体之间用管道连接,管道由左腔底部中心流入,切向右腔内壁流入右腔,相对传统坩埚结构以实现坩埚的自搅拌功能。并通过ANSYS 12/Fluent模块对自搅拌坩埚和传统坩埚流场分别进行数值模拟。对模拟结果进行对比分析,发现自搅拌坩埚较好地实现了自搅拌功能,对熔体温度、成分的均匀分布起到明显的促进作用,能很好地保证铸带质量。In the structural design of gating system, crucible was designed into two cavities, and two cav- ities were connected by a pipeline, and pipeline was flown from the left bottom center of the cavity to the right wall of the chamber in tangential direction into the right cavity to achieve the self-stirring effect. The flow field in stirring crucible and in traditional crucible was simulated, respectively, by the ANSYS 12/Fluent. The results show that the stirring crucible can realize the better function of the mixing, greatly improving the temperature, composition of liquid and degree of uniform distribution.
