【摘要】 异步轧制工艺可降低轧制力,并能突破同步轧制的最小可轧厚度。在工作辊径D=8mm,支承辊传动的四辊实验轧机上实现了异步轧制,进而在二十辊轧机上实现了异步轧制并进行了多辊轧机异步轧制实验研究。实验结果表明,多辊轧机异步轧制极薄带可降低产品最小可轧厚度,提高带材质量。在二十辊轧机上采用异步轧制可以获得宽75mm,厚度低于0.00mm的极薄带材。工作辊径与带材厚度的比值D/h大于8250,带材宽度与厚度比值B/h大于75000,达到同类轧机的先进水平。更多还原

【Abstract】 The technique of asynchronous rolling can decrease the rolling load and break the limitation of the minimum thickness being rolled on an ordinary rolling mill. At first, the asynchronous rolling was done on a 4-high experimental mill, driven by back up roll with a work roll of 8mm diameter. Afterwards, it was successfully carried out on a 20-high mill, and an extremely-thin strip with less than 0.001mm thickness and a width of 75mm has been obtained. The ratio of the work roll diameter to the thickness of the strip D/h is larger than 8250; the ratio of the width of the strip to its thickness B/h is larger than 75000, thus reaching the optimal level of the same kind of mills.更多还原
