By using tracking statistics on the production workshop,the rolling shear process,durability,tool sharpe-ning and other issues during the rolling shear processing of iron-based amorphous nanocrystalline alloy strips are summa-rized and analyzed.Statistically analysis of different widths of rolling shears is done,it is found that the effective working time ratio of rolling shears ranged from 65％to 88％,with an average effective working time ratio of 76.1％,and the effec-tive working time is unstable;the shearing mileage of rolling shears is between 3700m and 4200m,with an average shearing mileage of 3839.74m,and there is a large difference in tool durability,with the larger the shearing width of rolling shears,the longer the tool durability.The greater the shear width,the longer the durability;the radial removal of the tool during sharpening of the rolling shears ranges from 80μm to 150μm,with an average sharpening removal of 106μm,and the tool sharpening process has a decisive impact on the tool durability;finally,for the wear detection problem of the rolling shears,an acoustic emission signal can be used to conduct online inspection of the condition of the rolling shears.
