【摘要】 异步恒延伸轧制是一种轧制高精度带材的新方法。在实验室的φ90/φ200×200mm四辊轧机上,用异步恒延伸轧制法试生产了0.1～0.2×100mm,厚度偏差在±0.003mm范围内的高精度带材。实验结果表明:异步恒延伸轧制具有自然抵抗原始辊缝波动、变形抗力和原始厚度波动的能力,始终保持延伸系数恒定,从而能显著地提高带材的精度;异步恒延伸装置有张力自然调节的优异特性,它能起到一定的张力AGC的作用;并能有效地防止断带。异步恒延伸轧机具有设备简单,投资少,易控制的优点。更多还原

【Abstract】 Constant elongation asynchronous rolling is a new rolling process recently developed to facilitatethe production of high precision strip.0.1?0.2?00mm high precision strip with a gauge toleranceof?.003mm has been successively rolled on a ?90/200?00mm 4-high mill by this method.The results show that this rolling technique is possessed of the ideal salf-compensatory ability againstfluctuation in strip flow resistance,roll gap opening and entry strip thickness,and a constantelongation ratio is always maintained.Thereby,strips can be rolled with remrakably high precisioncomparable to that obtained by strip mills equipped with high efficient AGC.Strip breakageis reduced to a minimum.One of the most important features of the constant elongationasynchrounous rolling method is the capability of self-adjustment of strip tension,which makes itto function as a tension AGC system.Besides,the constant elongation asynchronous mill has additionaladvantages of simple in construction and easy to operate.更多还原
