The invention provides a method for eliminating the surface pinpoint defect of a BH steel plate. The method is characterized in that mixing production of steel types is performed by a continuous annealing set, wherein production scheduling of SPCC steel plates is performed before the production of the BH steel plate; and one to three coils of IF steel or SPCC steel plates are produced during the production of every seven to ten coils of the BH steel plates. The method achieves the purposes of eliminating the surface pinpoint defect and improving the surface quality by reasonably optimizing themixing production process and other processes based on existing steel type components and devices.
