采用活塞流及轨线模型，对行波磁场净化液态金属时，三角形及矩形管中夹杂物的去除效率进行了理论分析，找出了提高夹杂物去除效率的途径；对两种形状管的夹杂物去除效率进行了比较；确定了行波磁场能有效去除夹杂物的粒径范围
By using plug flow and trajectory model, the removal efficiencies of inclusions in triangular and rectangular tubes were theoretically analyzed when traveling magnetic field was used to purify liquid metal, and the ways to improve the removal efficiency of inclusions were found. Material removal efficiency were compared; determine the traveling wave magnetic field can effectively remove the particle size range of inclusions
