摘　　要：三层铝合金复合钎焊板是制造钎焊式热交换器的重要材料,其中4004/3003/4004是一种使用最为广泛的铝合金复合钎焊板。对4004/3003/4004铝合金复合钎焊板进行热轧复合,分析其包覆层宽度方向分布情况和上下包覆层厚度差异性,并研究不同初始包覆率下轧制后包覆率的变化规律,对实际生产中钎焊板包覆层厚度控制起到重要的指导作用。The three-layer aluminum alloy composite brazing plate is an important material for brazing heat exchanger,among which4004/3003/4004 is the most widely used aluminum alloy composite brazing plate. The hot rolling of 4004/3003/4004 aluminum alloy composite brazing plate was carried out,the distribution in the width direction of the cladding layer and the difference in the thickness of the upper and lower cladding layer were analyzed,and the variation law of the cladding rate after rolling was studied under different initial cladding rate,which played an important guiding role in the control of the thickness of the brazing plate in the factory.
