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。

Abstract

In the structural design of gating system

crucible was designed into two cavities

and two cavities were connected by apipeline

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 ANSYS12/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.
