| 中文摘要 | 宏观偏析普遍存在于铸造合金凝固过程中,严重影响了材料的使用性能。本文利用宏观偏析数学模型,分别对53 t钢锭和500 t铸件宏观偏析进行数值模拟研究。模型考虑了凝固收缩与等轴晶沉降,模拟结果和实验结果吻合较好。; Macrosegregation usually occurs during the casting alloy solidification process,which greatly deteriorate the service material performance. In this paper,by means of the mathematic model,numerical simulation researches are conducted for the cast macrosegregation of 53 t and 500 t ingots. Solidification shrinkage and equiaxial crystal settlement are considered in the model,the simulation result is well consistent with the test results. |
