摘　　要：通过介绍1系铝合金的特性和熔铸工艺的特点可知,铝箔对于1系铝合金熔体的氢含量和夹杂物含量要求很高,且铝合金中的Ti、Fe、Si含量以及Fe、Si相对含量对最终箔材的质量影响很大。为生产高品质的1系箔用铝合金扁锭和铸轧板,从原材料质量控制、化学成分控制、熔炼及精炼工艺控制、在线处理工艺以及铸造工艺控制等方面,简要论述了1系铝合金的熔铸工艺过程控制。By introducing the characteristics of 1 system aluminum alloy and the characteristics of the melting and casting process,it can be seen that the aluminum foil had high requirements for the hydrogen content and inclusion content of the 1-series aluminum alloy melt,and the contents of Ti、Fe and Si in the aluminum alloy and the relative contents of Fe and Si had great influences on the quality of final aluminum foil.In order to produce high quality aluminum alloy slab and cast-rolling plate for 1 series foil,the control of melting-casting process of 1 system aluminum alloy was discussed briefly from the aspects of raw material quality control,chemical composition control,melting process control,on-line treatment process and casting process.
