Study on the Free-Surface Flow of Silicon Melt in the CrucibleLi Yingchun;Wan Qun;Qin Fu General Research Institute for Non-ferrous Metals,Beijing,China摘 要:<正> The flowing of the free-surface-layer melt in the crucible has been studied by means of observing the movement ofthe mark particle on the free-surface of silicon melt.A new view......
Simulation of electromagnetic-flow fields in Mg melt under pulsed magnetic field WANG Bin(汪 彬), YANG Yuan-sheng(杨院生), MA Xiao-ping(马晓平), TONG Wen-hui(童文辉) Institute of Metal Research... and on the distribution of magnetic and flow fields were numerically studied. The pulsed magnetic field increases melt convection, which stirs and fractures the dendritic arms into pieces. These broken pieces......
