Method for eliminating defect of strip shape of hot-rolled high-strength steel

The invention relates to a method for eliminating a defect of strip shape of hot-rolled high-strength steel. The technological combination of skin rolling, batch annealing and roll straightening is introduced into a process for the plate rolling of the hot-rolled high-strength steel with a specification range of 3-18.4mm multiplied by 900-1800mm (thickness multiplied by width) and a yield strength not less than 600MPa, so as to eliminate an internal stress of the hot-rolled high-strength steel, obviously improve the shape quality, and enable a user to obtain good shape stability, which is capable of meeting the strict requirement of the user that the flatness is less than or equal to 2mm/m.
