通过研究ＺＡ２７合金准固相区的流变行为建立了合金在不同温区的流变模型．结果表明，在３８５－３９０℃和４００－４３０℃，合金的流变模型分别为六元件和五元件模型，并据此推导出合金的流变本构方程．六元件模型为：［Ｈ_１‖Ｓ_１］－［Ｈ_２‖Ｎ_１］－［Ｎ_２‖Ｓ］五元件模型为：Ｈ_１－［Ｈ_２‖Ｎ_１］‖Ｎ_１］－［Ｎ_２‖Ｓ］根据试验结果计算出各个温度下合金的流变参数，结合合金相图及ＤＴＡ曲线，确定合金凝固过程中的质量补缩与枝晶补缩停止温度分别为４２０℃和３９０℃，为ＺＡ２７合金的铸造工艺设计及凝固过程分析提供了重要依据．最后分析讨论了上引连铸ＺＡ２７合金的补缩条件，提出了满足铸坯补缩要求的上引连铸稳定工作条件．
By studying the rheological behavior of the quasi-solid zone of ZA27 alloy, the rheological model of the alloy in different temperature zones was established. The results show that at 385-390 ℃ and 400-430 ℃, the rheological model of the alloy is a six-element and five-element model respectively, and the rheological constitutive equation of the alloy is deduced. The six-element model is: [H_1∥S_1] - [H_2∥N_1] - [N_2∥S] The five-element model is: H_1- [H_2∥N_1] ∥N_1] - [N_2∥S] Calculate the temperature Under the rheological parameters of the alloy, the phase diagram of the alloy and the DTA curve were used to determine the quality of the alloy during the solidification process and the stopping temperature of the dendrite supplement were respectively 420 ℃ and 390 ℃. The casting process design and solidification process of ZA27 alloy Provide an important basis. Finally, the conditions of the shrinkage of the continuous casting ZA27 alloy are introduced and discussed, and the stable working conditions of the continuous casting with continuous casting are proposed.
