1、压延电子铜箔轧制与润滑性能研究熊桑,刘娜娜,夏垒(北京科技大学材料科学与工程学院,北京W0083)摘要:工艺润滑是保证压延铜箔轧制性能与表面质量的重要影响因索之一,目前没有专用铜箔轧制油,国内多沿用传统的铜板带轧制油,导致尺寸偏差、板面色差、表面光洁度较差等问题,为此本文对新型研制铜箔轧制油SMD-A.SMD-B和国外同类轧制油RN・Q的性能进行了对比研究。利用MRS-10A四球摩擦磨损试验机实验测其摩擦学性能,并通过冷轧实验研究轧制油轧制工艺润滑效果。实验结果表明:采用工艺润滑后,能够降低轧制摩擦系数和轧制
2、总压力,改善润滑条件;新研制轧制油SMD-B摩擦学性能更优,其Pb值达到T559N,与国外同类轧制油RN・Q相比提高了35.7%,且磨斑直径与摩擦系数分别下降了20.9%和15.8%;使用轧制油SMD-B润滑时,与不润滑时的轧制总压力相比降低了26.6%左右,同时可以使铜箔轧制更薄,最小可轧厚度达到2Sgm,且轧后表面更光亮、平整。关键字:压延铜箔;工艺润滑;摩擦学性能;最小可轧厚度;表面质量中图分类号:TG335.12文献标识码:AStudyonLubricatingPerformancesduringRo
