摘要/Abstract

摘要： 利用CFD商用软件Flow-3d,对内外复合冷却结晶器内钢水充型过程流场温度场耦合作用下的流动和凝固状况进行数值模拟,得到了流场温度场的分布图和充填过程中自由表面的位置和形状图。分析了板坯连铸充型过程中流场温度场对钢水凝固的影响。结果表明内冷却器可改善钢水的流动，有利于钢液中的夹杂物上浮,加快结晶器内钢液的凝固

Abstract: The flow and solidification status of molten steel with coupling flow field and temperature field in inner- outer couple cooling mold has been simulated by using CFD commercial code Flow-3 d software to get distributing diagrams of flow field and temperature, and free-surface level and shape diagram. The influence of flow field and temperature field in slab concasting filling process on solidification of molten steel was analyzed. It is indicated that the inner cooler could improve the molten steel flow status which is favourable for inclusion floating up in molten steel and increasing the solidification rate of molten steel
