摘要
考虑和分析了钢液RH非平衡脱碳过程的特征,基于冶金反应工程学和非平衡态热力学及气-液两相流的双流体模型和修正的紊流k-ε型,引入熵衡算和非线性耗散因子,对该过程提出了一个新的三维数学模型,给出了该模型的具体细节,包括控制方程的建立、修正的k-ε双方程模型、相应的源项和边界条件的确定等;对90t装置内的RH和RH-KTB精炼过程,讨论和确定了该模型各有关参数.
The characteristics of the non-equilibrium decarburization process during the RH refining of molten steel have been considered and analyzes.On the basis of the fundamentals of metallurgical reaction engineering and non-equilibrium thermodynamics,as well as the two-fluid(Euierian-Eulerian)model for gas-liquid two-phase flow and a modifiedλ-εmodel for turbulent flow,introducing the entropy balance and a non-linear dissipation factor,a novel three-dimensional mathematical model for the process has been propose...
