The invention discloses a method for eliminating non-oriented electrical steel surface crack defects and belongs to the technical field of electrical steel rolling. The method is applicable to the non-oriented electrical steel with the Si content being 0.7wt%-1.6 wt% and the P content being 0.05wt%-0.1 wt%. Specifically, during normalizing and pickling, the dew point of a normalizing furnace is controlled below 0 DEG C, the normalizing temperature is controlled below 1000 DEG C, the normalizing tension is controlled at 9-12 N/mm<2>; and the shot blasting speed is controlled at 65-75 m/s. According to the method, by improving the normalizing and pickling process and strictly controlling process parameters, under the collaborative effect of the process conditions of the dew point of the normalizing furnace, the normalizing temperature, the normalizing tension and the shot blasting speed, influences of normalizing and pickling on the surface quality of the non-oriented electrical steel can be reduced, the surface crack defects of rolled belt steel are eliminated, the non-oriented electrical steel good in surface quality is obtained, and therefore the product market competitiveness is improved.
