The invention discloses a method for removing a color difference defect of high-strength phosphorus-containing IF steel surface. The method comprises the steps of heating high-strength phosphorus-containing IF steel billets; rough rolling and finish rolling the heated high-strength phosphorus-containing IF steel billets to obtain finish-rolled high-strength phosphorus-containing IF steel plates; coiling the finish-rolled high-strength phosphorus-containing IF steel plates to obtain high-strength phosphorus-containing IF steel hot-rolled coils; cold rolling the high-strength phosphorus-containing IF steel hot-rolled coils to obtain cold-rolled high-strength phosphorus-containing IF steel plates, wherein the cold rolling reduction single pass rate is 30% or below; and continuously annealingthe cold-rolled high-strength phosphorus-containing IF steel plates. According to the method disclosed by the invention, the technical problem of the color difference defect of the high-strength phosphorus-containing IF steel surface in the prior art is solved or partially solved, and the color difference defect of the high-strength phosphorus-containing IF steel surface is removed, so that the technical effect of the high-strength phosphorus-containing IF steel surface quality is improved.
