基于精力和质量的能量守恒定律,并且考虑在集中地上的陶器的模子和温度回答的液体钛和氧化锆之间的化学反应的效果,为热和集体转移的数字模拟的一个全面数学模型被建立了学习在液体 Ti 和 ZrO2 陶器的 mold.With 之间的界面的反应建议模型,数字模拟是 preformed 调查倒温度和 holdin 的效果
Based on the conservation laws of energy and mass, and taking into account the effect of chemical reaction between liquid titanium and zirconia ceramic mold on the concentration field and the temperature field, a comprehensive mathematical model for numerical simulation of heat and mass transfer has been established to study the interfacial reaction between liquid Ti and ZrO 2 ceramic mold. With the proposed model, numerical simulations were preformed to investigate the effects of pouring temperature and holding time on the oxygen concentrations and reactive layer thickness in metal. The results showed that both the oxygen concentration and the thickness of reactive layer in metal increase with the increase of the holding time and the pouring temperature. The development of reactive layer thickness with time consists of three stages: inoculation (0-1 s), linear increase (1-5 s) and parabolic increase (after 5 s).
