1、 基于基于FLOW-3D仿真的横浇道的横浇道 集渣效果研究集渣效果研究 I 摘 要 夹杂缺陷对铸件产生严重破坏作用。在浇注过程中，横浇道具有一定捕获 夹杂物的功能， 即集渣作用。 为了探索横浇道的集渣作用， 本文以含碳量为 0.50% 的碳钢为例，并利用 FLOW-3D 模拟软件研究了横浇道的形式、浇注系统的类型、 集渣包等对集渣效果的影响。 仿真结果表明： 横浇道充满可以明显提高集渣效率， 半封闭式浇注系统比封闭式和开放式集渣效果好；忽略阻力系数的影响，横浇道 横截面的变化及弯曲不利于提高集渣效果，其中雨淋式集渣效果最好；横浇道上 设置集渣包有利于提高集渣效率，其中离心式集渣包集渣效果最好。

To explore the effect of drag collection of runner,This paper takes 0.50% carbon steel for example, and it studies the effect of the for

3、m of runner, the type of gating system, the dirt trap on drag collection by using FLOW-3D simulation software . Simulation results show that: runner residue being filled can significantly improve the collection efficiency, and the semi-closed gating system is better than the closed and the open one;

4、 Ignoring the impact of the resistance coefficient, the cross section changes of the runner and its bending are not suitable for increasing the effectiveness of drag collection , and the rain-type gating system is the best ; Setting diet trap on runner is good for raising the effectiveness of drag collection, and the whirl-gate diet trap is the best for the set of Java package.
