The invention discloses a method for producing oriented electrical steel with excellent surface quality, and belongs to the technical field of oriented electrical steel production. The method comprises the following processes of: heating a casting blank at the temperature of between 1,000 and 1,190 DEG C, and then performing hot rolling; normalizing the hot rolled plate at the temperature of between 980 and 1,100 DEG C, and washing the plate by using acid; cold-rolling the plate to the thickness of a finished product under high rolling reduction rate of 86 to 93 percent; heating the cold rolled steel plate to the temperature of between 750 and 860 DEG C, and nitriding in ammonia-containing nitrogen and hydrogen mixed gas; performing decarburizing annealing at the temperature of between 800 and 860 DEG C; then coating a magnesium oxide isolation layer; raising the temperature to 1,200+/-50 DEG C at the speed of 10 to 20 DEG C per hour in the nitrogen and hydrogen mixed gas, preserving the heat for 10 to 20 hours in hydrogen, and completing high-temperature annealing to obtain a finished product of secondary re-crystallization textures; and coating an insulating stress coating. The method has the advantage of producing the oriented electrical steel without defect on the surface and with strong adhesive force and uniform magnesium silicate bottom layer.
