Microstructural Characterization of Novel Ni-Containing Nd-Fe-B Strips by Strip Casting Zhu Xuexin1,Li Chengdong1,Shi Likai1 (1.National Engineering Research Center for Non-Ferrous Metal Composites, General Research Institute for Non-Ferrous Metals, Beijing 100088, China) Abstract:The characteristics of novel Nd-Fe(Ni, Co, Al)-B microstructure prepared by strip casting technique were studied......
University, Changsha 410083, China) Abstract: Based on the analyses of aluminum melt flow, solidification, heat transfer during the process of twin-roll casting, a coupling mathematical model of aluminum thin-gauge high-speed casting was developed, which included the casting roller shell. At the same time, Galerkin method was adopted to solve the coupling model. The fluid field and temperature field......
was possibly an additional factor which attributed to the entrapment of the liquid-EPS residue in the casting. Due to the concave profile, the liquid metal advanced preferentially along the mold walls... increases, the density of casting also increases and reach maximum when the filling velocity of metal is 75 mm/s. The misrun or other pyrolysis defect is not easy to occur in the castings. If the filling......
板坯电磁制动结晶器内流体流动的研究于湛1,张振强1,任忠鸣1,雷作胜1,邓康1(1.上海市上海大学现代冶金与材料制备重点实验室)摘 要:用Hg模拟了高速板坯电磁制动结晶器内钢液的流动,使用超声波Doppler测速仪测量了结晶器内液体的流速和液面的波动,分析了静磁场对流体流动的作用,研究了静磁场对浸入式水口出流,结晶器内金属液流动,液面波动,液面流动及对器壁冲刷强度的影响.结果表明:静磁场使浸入式水口出流受到抑制,上部环流区的流动增强,下部环流区流动减弱;改善了自由液面的波动和流动.静磁场不仅具有制动钢液流的作用......
of the continuous casting technology for producing bimetallic ingots is the interface behavior between two metals. The interface can be under the contact of liquid melt of one metal with a solid surface... in the lower crucible was pushed downward by air pressure in sealed pressure cover when the continuous casting was conducted. Firstly, the external metal formed a tube and then the liquid inner metal......
