摘要
针对于传统颗粒增强镁合金搅拌釜在实际应用过程中存在的问题,本题组自主设计了新型搅拌装置。在传统搅拌装置基础上搅拌釜底设置有管道通气口,可将碳化硅等颗粒材料置于其中,在搅拌釜搅拌过程中颗粒将会随通入的气体弥散于镁合金液中,相比于传统的搅拌装置碳化硅的分散性有所提高,这样可以在低速搅拌下得到高质量的镁合金成品。采用数值模拟方法对于新型反应釜的速度场、压力场、颗粒分布情况进行模拟,从而验证了设计的优越性。
In view of the problems existing in the practical application of the traditional particle reinforced magnesium alloy stirring kettle,the research group independently designed a new stirring device.On the basis of traditional stirring device.There is a pipe vent is added at the bottom of stirring kettle,in which SiC and other granular materials can be placed.In the stirring process of stirring kettle,the particles will be dispersed in magnesium alloy liquid with the incoming gas.Compared with the traditional stirring device,the dispersion of SiC is improved,so that high-quality magnesium alloy products can be obtained under low-speed stirring.The numerical simulation method is used to simulate the velocity field,pressure field and particle distribution of the new reactor,which verifies the superiority of the design.
