摘要
采用SEM和EDAX分析技术 ,观察和分析了铸轧铝带的表层夹杂缺陷。结果表明 ,夹杂尺寸大约在 5～ 2 0 0 μn之间 ,夹杂含有O ,C ,S ,Cl ,Na ,K ,Ca ,Fe ,Mg ,Si等元素。原辅材料中的杂质、熔炼铸轧过程的污染及净化处理不当是形成夹杂的原因。表层夹杂的遗传将导致箔材断带和弥散性穿孔。严格控制和改进工艺 。
The surface inclusion in cast rolling aluminum strip was observed and analyzed by means of SEM and EDAX. The results showed that the inclusion size ranges around 5～200μm and the inclusion consists of O, C, S, Cl, Na, K, Ca, Fe, Mg,Si. Impurity in raw and auxiliary materials, pollution in smelting casting process and abnormally purified treatment are the reason of forming inclusion. Heredity of the surface inclusion results in aluminum foils cracking and forming dispersively penetrated hole. The formation of entrapped slag could be prevented effectively by strictly controlling and up grading the process
