热镀铝锌后处理膜类型及成膜工艺控制技术

The Types of the Hot-Dipped Galvalume Post-Treatment Film and the Control Technology of Film Forming Process

总结了梅钢冷轧厂热镀铝锌机组5种后处理膜的性能特点及其产品适用范围,并按照用户使用要求和产品服役环境,合理地选择后处理膜的类型,使后处理膜具备应用性能。重点阐述了热镀铝锌机组后处理工序的控制要点,以便获得均匀、稳定的膜厚;特别是总结了表面质量缺陷-斑迹和漏涂的改进对策,以减少质量损失,提高热镀铝锌产品的综合使用性能。

The performance characteristics and product application scopes of five kinds of post-treatment films of the hot-dipped Galvalume line in Meigang cold rolling plant were summarized,and the type of post-treatment films was reasonably selected according to the user ’s requirements and the products service environment to make the post-treatment films have application performance. The controlling points of the post-treatment process of the hot-dipped Galvalume line was focused on,so as to obtain uniform and stable film thickness. In particular,the improvement measures of surface defects-stains and missing coating defects were summarized to reduce quality loss and improve the comprehensive performance of the hot-dipped Galvalume products.
