某厂铝箔精轧机,长期以来,存在着轧辊频繁断裂的严重问题。虽经多次改进,但都未能收到予期的效果。本文根据铝箔轧制的特点,从调查统计轧辊的断裂规律入手,结合对轧辊负荷,辊颈硬度的实际测定,对轧辊规律性的断裂特征及其断辊的主要原因作了分析和论述,同时还从设计,制造等方面提出了改进方案。 A factory aluminum foil finishing mill, for a long time, there is a serious problem of frequent roll break. Despite many improvements, but failed to receive the expected results. In this paper, according to the characteristics of aluminum foil rolling, starting with the investigation of the breaking rules of the rolling rolls, combining with the actual measurement of roll load and roll neck hardness, the regular breaking characteristics of roll and the main reasons of the broken roll are analyzed and discussed. Meanwhile, Also from the design, manufacture and other aspects of the proposed improvement program.
