University, Changsha 410075, China) Abstract: Taking account of the interactions between particles, a kinematic model of granular bed in rotating kiln was established using discrete element method based on its particle size. Using spherical quartz sand as bed material, transverse bed motions and particle force chains were studied through numerical calculation of the model. Taking the Froude......

School of Civil and Environmental Engineering, University...) Abstract: In order to enhance the leaching rate of vanadium, the fluidized oxidizing roasting was adopted to pretreat the high-carbon stone coal from Guangxi province, China. The thermodynamics......
Microstructure, precipitates and mechanical properties of powder bed fused inconel 718 before and after heat treatmentLe Zhou,Abhishek Mehta,Yongho Sohn摘 要:IN718 alloy was fabricated by laser powder bed fusion(PBF) for examination of microstructure, precipitates and mechanical properties in the as-built state and after different heat treatments......
of carbon cathode during the heating-up process by using the same resistivity coke bed. Many defects such as high difference in temperature in the cathode, non-uniform temperature among the cathode surface... found. In order to solve this problem, an optimization using increasing resistivity coke bed from the side of the cell to the center to preheat the cell was carried out. The results show......
, Southwest Jiaotong University,Chengdu 610031, China) Abstract: In order to control the deformation of the end of the unit bed slab and strengthen the integrity of the slabs, the dowel bar setting measure... the integrity of the unit bed slabs; its ability to control the deformation of the plate end is directly related to the bending stiffness ratio between the dowel bars and the unit bed slab......
