摘　　要：对于3104铝合金罐体料生产,断罐、罐底起皱/底裂和水煮发黑控制是三大技术难题,具有一定的普遍性,也需要结合具体问题具体分析。为了进一步提高罐料的国际竞争力,南山结合国外案例做了三个实例分析,重点对铝锰合金第二相分布对断罐性能的影响进行了分析,在当前激烈的国际市场竞争中,金属质量和产品服务是不断拓展市场的关键,最后南山对断罐、罐底起皱/底裂和水煮发黑的原因进行了归纳。For the production of 3104 aluminum alloy can sheets,can tearing,bottom wrinkling/bottom cracking and dome staining are three major technical problems,which have a certain universality and need to be analyzed in combination with specific problems.In order to further improve the international competitiveness of can sheets,three case analysis examples were taken in combination with foreign complaint cases,focusing on the impact analysis of second-phase distribution of aluminum-manganese alloy on the can tearing performance.In the current fierce international market competition,metal quality and product service are the key factors to continuously expand the market.Finally,Nanshan summarized the causes of can tearing,bottom wrinkling/bottom cracking and dome staining.
