提高铸轧坯料质量降低双零铝箔针孔率

Measures on reducing pinhole rate of double rolling aluminum foil being produced with continuous cast stock

结合生产实践,阐述了铸轧坯料质量对生产双零铝箔产生针孔的影响,涉及生产铸轧坯料的原辅材料、熔体处理、晶粒细化、板形控制、铸轧辊表面粗糙度等对双零铝箔针孔率的影响。在实际生产铸轧坯料的过程中,在以上各方面采取相应的技术措施,提高了铸轧坯料的质量,有效地控制了双零铝箔的针孔数量和尺寸。

The quality control measurements of double rolled aluminum foil have been investigated according to the production practicel The influence of raw and auxiliary materials, microstructure, melt treatment, grain refinement, flatness control and roll surface roughness on pinhole rate of double rolled aluminum foil has been indicated. The corresponding solution plan and measures have been put forward.
