平辊压扁轧制纺织器材专用超窄钢带的工艺研究

介绍了超窄钢带的两种主要生产方式及其优点,主要研究了纺织器材专用高精度超窄钢带的平辊压扁轧制成型工艺,重点探讨了圆钢丝压扁轧制的变形特点,分析了钢丝在压扁轧制中的变形规律和压力分布情况,总结了目前用于计算宽展的公式,通过试验数据验证,M.Kazeminezhad宽展公式在计算单道次或者第1道次压扁轧制宽展量时,精度较高;但用于计算多道次轧制宽展量的误差较大,且公式(5)计算精度高于公式(6).同时,阐述了国内外钢丝平辊压扁轧制工艺的研究动态,从3个方面指出今后钢丝压扁轧制成型工艺研究的重点.

Research of Flattening Process of Super-narrow Steel Band for Textile Accessories

Intoduction is done to the two main methods of processing super-narrow steel band as well as the process advantage.Research is mainly made to the flattening process of hi-precision super-narrow steel band for textile accessories.The deforming features of the flattened wire is highlighted in the flattening process as well as the deforming regulation and the pressure distribution.Summerization is made to the in-service formula for spreading range.Data experiment that the formula by M.Kazeminezhad has higher precision in calculating the spreading range of single rolling or the first rolling,yet with big error in calculating the spreading range of multi-rolling and the formula(5) is more precise than the formula(6).Introduction is made to development of the flattening processes both at home and abroad.Lastly,viewed from three aspects,the keypoints are put forth regarding the wire flattening process in future development.
