摘　　要：针对下游用户反馈铸轧铝箔坯料出现白条缺陷,通过对白条缺陷进行观察和分析后,找出其产生的原因,并对铸轧工艺进行调整.通过调整熔体液面的稳定性、炉口熔体的温度、铝-钛-硼丝加入的位置和铸嘴分流块的位置,使铸轧坯料结晶组织均匀一致,从而避免了冷轧、箔轧产品出现的白条缺陷.According to the feedback from the downstream users,the white strip defect appeared in the casting and rolling of aluminum foil blank.After the observation and analysis of the white strip defect,the causes were found out and the casting and rolling process was adjusted.By adjusting the stability of the molten surface,the temperature of the melt at the mouth of the furnace,the joining position of the Al-Ti-B wire and the casting nozzle splice,the crystal structure of the casting and rolling billet was uniform,and the defects of white strip in cold rolling and foil rolling products were avoided.
