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 the pouring system, the crucible is designed into two cavities, and the two cavities are connected by pipes. The pipe flows in from the bottom center of the left cavity and flows into the right cavity through the inner wall of the right cavity. Compared with the traditional crucible structure, Self-stirring function. The flow field of the self-stirring crucible and the traditional crucible were numerically simulated by ANSYS 12 / Fluent module. The simulation results are compared and analyzed. It is found that the self-stirring crucible has better self-stirring function, obviously promoting the uniform distribution of the melt temperature and the composition, and can well ensure the quality of the casting belt.
