【摘要】 从传热、传质和动量传输原理出发,建立定量描述连铸坯凝固过程的统一数学模型,将连铸坯凝固过程的三个区(固相区、固液两相区、液相区)的三个场(温度场、流场、溶质场)的定量描述统一在用同一组方程,实现了连铸批凝固过程的成分分布的数值模拟。根据生产的实测结果,初步证明本文建立的统一模型和编制的软件是比较合理可靠的。更多还原

【Abstract】 A continuum model integrated with heat, mass, momentum transport behavior is applied to simulation of solidification process of continuous casting billets. A continum differential equation set with describes three fields(temperature field, fluid flow field, solute field)in three Zones(liquid zone, solid zone, liquid-solid zone)is used to simulate temperature field, fluid flow field, solution field of solidification process in continuous casting billets. The model and software have been testified much reasonable and reliable in practice.更多还原
