根据单晶连铸技术原理,分析了单晶连铸过程的主要影响因素,并根据流体力学模型以及传热模型计算了液体金属压力和牵引速度。结果表明:根据模型确定的参数是合适的,并在铸型温度为690～780℃、冷却距离为50mm、牵引速度为1.1mm/s、开始时静压头为5～6mm、连铸时动压头为2mm左右的工艺条件下获得了Φ8mm高品质的单晶铝线材。 According to the principle of single crystal continuous casting, the main influencing factors of single crystal continuous casting process are analyzed, and the liquid metal pressure and traction speed are calculated according to the fluid mechanics model and the heat transfer model. The results show that the parameters determined according to the model are suitable. When the mold temperature is 690 ~ 780 ℃, the cooling distance is 50mm, the traction speed is 1.1mm / s and the static pressure head is 5 ~ 6mm at the beginning, Indenter for about 2mm under the conditions obtained Φ8mm high-quality single crystal aluminum wire.
