针对酸轧IF软钢切边合格率低的情况，研究了导致酸轧切边缺陷的要素和预防措施，并研究了切边剪的切边原理。通过对上线前刀具的间隙和重叠量偏差的限定，提高刀具硬度，合理搭配剪切间隙和重叠量，保持稳定高速的切边速度等措施，使IF软钢切边合格率得到极大地提高，为生产符合宽度公差要求的产品奠定了基础，并保证了轧机的顺利轧制和下道产线的稳定顺行。
Aiming at the low percent of pass of side trimming of IF steel after pickling and cold rolling, the essential fac-tors that caused the defects of side trimming and the precautionary measures were investigated and the operational princi-ple of side trimmer was researched. The measures such as limiting the side clearance and the overlapping deviation of the side trimmer before it works, increasing the hardness of the side trimmer, reasonable matchup of the side clearance and the overlapping, and keeping the stable and high speed of side trimming were taken. All the above measures increased the per-cent of pass of side trimming greatly, which laid the foundation of producing the rolled steel within width allowance and al-so ensured the smooth operation of rolling mill and stable production.
