The invention discloses a method for improving head warping and buckling of a rolled piece, which relates to the technical field of metal material processing and comprises the following steps of: controlling the fit clearance between a roller flat head and a roller transmission shaft flat head sleeve within 1mm in a manner of surfacing the roller flat head or replacing a lining plate of the roller transmission shaft flat head sleeve; the size of the roller bearing seat is adjusted by adding a gasket between a roller bearing seat body and a bearing seat sliding plate, and the fit clearance between a rolling mill housing and the roller bearing seat is controlled within 0.5 mm; and before a rolled piece is gripped, the rotating speed of the roller is reduced to be within 50 mpm. According to the method, the deviation between the actual rotating speed and the set rotating speed of the roller is reduced, the stability of the roller space position is improved, the stability of the roller speed difference of the upp
