A 3-D comprehensively coupled model has been developed for iron-carbon binary system to describe the turbulent fluid flow, solidification and solute transport in the parallel type mold of thin slab.
针对薄板坯平行板型连铸结晶器,建立了Fe-C二元合金紊流流动、凝固及溶质传输的三维耦合数学模型；并与水口模拟计算相结合,计算、分析了薄板坯平行板型结晶器内钢液的紊流流动、凝固及溶质分布,计算结果表明,由于薄板坯厚度尺寸限制,钢液液流冲击深度相对传统板坯明显减小,出水口射流对窄壁的冲击减弱,而对铸坯宽面的冲刷加强,出结晶器后,钢液流动变为向下的均匀平推运动,在结晶器出口处,由于钢液流动、凝固及溶质传输的相互作用,使得铸坯宽面靠近窄壁处的凝固壳厚度最薄,并在此处产生溶质分布强烈变化,易导致拉漏缺陷。
