FINITE ELEMENT NUMERICAL SIMULATION OF TEMPERATURE FIELD IN METAL PATTERN CASTING SYSTEM AND "REVERSE METHOD" OF DEFINING THE THERMAL PHYSICAL COEFFICIENT L. Chen1,P.N. Song1,P.L. Wang1... distribution of casting system during the solidification process was provided, which took the latent heat of phase change, the conditions for convection, and the interface heat transfer coefficient......
Mathematical model of flow characteristic in multi-strand continuous casting tundishes Hongwei PAN1,Shusen CHENG1 (1.School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, Beijing 100083, China) Abstract: new model can better capture the deviation of reality flow pattern from ideal plug flow pattern, and reflects the feature of plug flow. Key words......

becomes smaller gradually as the casting proceeds.When the flow reaches a certain depth,two types of flow patterns can be observed in the upper zone of the mold.The first flow pattern is to flow...Simulation of the continuous casting process in a mold of free-cutting steel 38MnVS based on a MiLE methodYun-jin Xia1,2),Fu-ming Wang1,2),Jin-long Wang1,2),and Guo-zhong Li3) 1) School......
investment casting made by Zr(CH3COO)2-Y2O3 shell in vacuum casting was studied.Statistic was manipulated to study the distributions and types of the reaction layers. The morphology and composition... diffraction(XRD).Composition of the shell reaction zone was measured by X-ray fluorescence(XRF) method. The results suggest the reaction contains oxidation and element evaporation, and the melt reacts......
Investigation of Out-Phase Electromagnetic Casting of Aluminum Alloy () 摘要:The influences of out-phase electromagnetic field on the as-cast structure of horizontal direct chill casting aluminum... an electromagnetically induced forced flow in the melt, which, in turn, changes flow pattern and temperature field in the mold. The as-cast structure of the ingot can be greatly improved by the changes of flow pattern......

The cracks and cracked section were examined... surface. Key words: casting roller shell; crack; heat fatigue; corrosion; structure characteristics  ......
Trans. Nonferrous Met. Soc. China 22(2012) 2092-2097 Effect of pattern coating thickness on characteristics of lost foam Al-Si-Cu alloy casting Majid KARIMIAN1, 2, Ali OURDJINI2, Mohd HASBULLAH..., Iran Received 17 November 2011; accepted 18 April 2012 Abstract: An experimental study on lost foam casting of an Al-Si-Cu alloy was conducted. The main objective was to study the effect of pattern......
scheme is as follows: Test 1: gravity casting and alumina based mould shell; Test 2: gravity casting and zirconia based mould shell; Test 3: centrifugal casting and alumina based mould shell; Test 4: centrifugal casting and zirconia based mould shell. The samples were cut from the casts in the reaction interface. The size of the samples was 5 mm×5 mm×5 mm. After being burnised, polished......
