摘　　要：通过在自行研发的水平式热型连铸设备上制备Al-1%Si合金线材的试验研究,分析型口温度、连铸速度及冷却能力等工艺参数对铸锭表面质量的影响,提出了制备Al-1%Si合金的优化工艺参数。同时,利用本试验制备的Al-1%Si合金线材和传统铸造多晶Al-1%Si线材作试样,分析两者的室温拉伸性能。结果表明,热型连铸制备的Al-1%Si合金线材和传统铸造多晶Al-1%Si线材相比,屈服强度提高41.4%,屈强比提高37.8%,伸长率提高49.1%,并具有良好的导电性能。The effect of process parameters of continuous casting with heated mould such as mould temperature, casting speed and cooling capability on surface quality of Al-1%Si wire was analyzed by the study of the fabricating of Al-1%Si alloy wire on the self-made horizontal heated-mold continuous casting equipment. The rational process parameters of the fabricating of Al-1%Si alloy were obtained. The tensile properties at room temperature of the Al-1%Si alloy wire were analyzed and discussed.It is found that the yield strength of the Al-1%Si alloy wire fabricated by the continuous casting with heated mould is higher 41.4%,the ratio of yield strength to tensile strength is higher 37.8% and the elongation is higher 49.1% than that of the poly-crystal ingot wire.The electrical property is also excellent.
