摘要

利用Anycasting铸造模拟软件

对采用金属型倾转铸造镁合金进气歧管的工艺进行了研究。通过正交试验和数值模拟

找到倾转铸造镁合金进气歧管的最优工艺参数。正交试验表明

金属型预热温度对倾转铸造镁合金进气歧管的模拟结果影响最大

然后依次为倾转速度、浇注温度、浇口杯预热温度。在浇注温度为750℃

上型预热为450℃

下型预热为550℃

浇口杯预热为550℃

倾转速度为2.71r/min的条件时

模拟结果最好。

Abstract

Filling process of magnesium alloy air-intake manifold in permanent tilted casting was simulated by the Anycasting software.The optimized processing parameters were obtained by orthogonal testing and numerical simulation.The orthogonal testing reveals that the factors influencing filling process are as follows:pre-heated temperature of mould

then tilted velocity

pouring temperature and then preheated temperature of cup.
