Material flow control technology of ironmaking and steelmaking interfaceHUANG Bang-fu(黄帮福)1, TIAN Nai-yuan(田乃媛)2, SHI Zhe(施哲)1, DING Yue-hua(丁跃华)1(1. Faculty of Metallurgical and Energy Engineering...:In order to achieve higher efficient cohesion match of procedure and equipment between ironmaking and steelmaking interface, the theory of multi-dimensional material flow control was applied to analyze......
slurry with shape factor of 0.76-0.90 and grain diameter of 48-68 μm can be prepared. With increasing the number of the curves or decreasing their diameters, the morphology and size of the primary α(Al) grains will be improved. The alloy melt has the effect of "self-stirring" in the serpentine curve, which can make the primary nuclei gradually evolve into spherical and near-spherical grains. Key......
