摘要
真空感应熔炼过程中连铸中间包内温度梯度与钢液流动对固体夹杂物的去除有重要作用,其直接影响钢液的纯净度.分析了连铸中间包内温度场、流场及应力场耦合数值模拟计算的现状,基于此,总结了多场耦合作用下夹杂物去除数值模拟的问题,介绍了热流耦合、流固耦合以及流固热耦合模拟方法,最后提出了流热固耦合下夹杂物去除数值模拟的建议.合理地控流装置组合和耐材选择可提高钢液质量.
Abstract
The temperature gradient and liquid steel flow in the tundish of continuous casting in the vacuum induction melting process play an important role in the removal of solid inclusions,which directly affect the purity of liquid steel.Based on the analysis of the current situation of numerical simulation of temperature field,flow field and stress field coupling in continuous casting tundish,the numerical simulation of inclusion removal under multi-field coupling is summarized.The heat flow coupling,fluid solid coupling and fluid solid thermal coupling simulation methods are introduced.The numerical simulation of inclusion removal under fluid-thermostructure coupling is proposed.A reasonable combination of flow control devices and a selection of resistant materials can improve the quality of liquid steel.
