摘　　要：分析了铝合金铸轧卷表面出现横向条纹的原因,改变工艺参数和铸嘴结构进行了试验,确定采用三级分流铸嘴替换传统的三导块铸上嘴,能有效地减少铸轧卷表面的横向条纹。This thesis analyzed the cause of transverse stripe on the surface of aluminum alloy casting-rolling coil. Through experiments on changing technological references and the structure of casting nozzles,this thesis confirmed that using three level by-pass casting nozzles, instead of traditional three-guide-block casting nozzles, could reduce transverse stripe effectively.

关 键 词：铝合金铸轧卷 横向条纹 三级分流铸嘴
