摘　　要：在５００ｍｍ×１２００ｍｍ热轧机上进行１４２０铝锂合金的热轧试验，铸块加热温度３８０～４４０℃，保温时间２～１０小时。结果表明，１４２０铝锂合金适宜的热轧开坯温度为３９０～４２０℃，铸块保温时间应不小于8小时,道次压下量应控制在５％～２０％。The hot rolling process of Al-Li alloy 1420 was experimentally investigated by using a 500×1200mm hot rolling mill in the paper .Heating temperature is 380～440℃,preserving time is 2～10h for temperature.The results show that the favorable break-down temperatures for alloy 1420 is 390～420℃，preserving time is at least 8h for slabs and pass reduction should be controlled within 5～70%
