The invention discloses a production method for non-oriented electrical steel. The production method comprises the working procedures of converter smelting, RH refining, heating and rolling; in the RH refining working procedure, when alloying is carried out, calcium-containing silicon iron or a calcium-containing alloy is added to conduct micro-calcium treatment, and the content of calcium in the steel ranges from 10 ppm to 30 ppm; in the heating working procedure, the highest heating temperature is not higher than 1170 DEG C; and in the rolling working procedure, the roughing RDT temperature is controlled to range from 970 DEG C to 990 DEG C. According to the method, the RH completely rises directly, the LF temperature rise link of the technological process is omitted, the process is smoothened, and therefore the production cost is reduced; according to the method, sequence continuous casting stabilized production of the electrical steel is achieved, the highest continuous casting number is larger than 15, and most economical production within the service life of a middle ladle is achieved; according to the method, the oxidation iron sheet structure of the surface of an obtained steel belt is effectively improved, the surface quality is greatly improved, and the stage of the surface of the steel belt obtained after cold rolling is improved; and by means of the method, mixed rolling between the electrical steel and a common product is achieved, and the yield of a production line is released to the maximum degree.
