Abstract：Aiming at the problem of large head and tail width fluctuation during in a 2 050 mm hot rolling line,precise width control was achieved by optimizing the short-stroke control model and tracking system.Key measures included correcting the calculation logic for the contact arc length of the sizing press hammer,developing a parameter calculation tool,and improving the tail tracking program.After implementation,the head-tail width deviation was stabilized below 3 mm,reduced from over 10 mm.Narrow-width defects decreased,the trimming rate was lowered,and the yield rate improved significantly,providing an effective solution for similar production lines.
