重力倾转铸造7A09铝锭的数值模拟及试验验证

Numerical Simulation and Experimental Verification of Gravity Tilting Casting Process for 7A09 Aluminium Ingot

基于AnyCasting软件模拟了采用自主研发的重力倾转铸造设备生产的7A09铝合金铸锭的生产过程,得出了最佳的生产工艺参数,并对模拟结果进行了实际验证。结果表明,当浇口杯中金属液含量为50%、倾转速度为π/(14)rad·s^(-1)、模具预热温度为100℃以及浇注温度为700℃时,可制备出品质合格的7A09铝合金铸锭。

The optimized process parameters of self-developed gravity tilting casting equipment were analyzed to prepare 7 A09 aluminum alloy ingot by using Anycasting software,and practical production was conducted based on the optimized parameters.The results show that the qualified 7 A09 aluminum alloy ingots can be prepared sucessfully at 50% gate cup,1/14πrad/s tilting speed,die preheating temperature of 100 ℃ and casting temperature of 700 ℃.
