The invention discloses a semi-process cold-rolling non-oriented electrical steel and a production process thereof, which mainly solves the technical problems that the prior art is high in energy consumption, large in pollution and high in cost. According to the technical scheme, the semi-process cold-rolling non-oriented electrical steel is a special steel which comprises the following ingredients by mass: not more than 0.01% of C, not more than 0.015% of P, not more than 0.012% of S, not less than 0.4% and not more than 0.60% of Si, not less than 0.6% and not more than 0.8% of Mn, not less than 0.15% and not more than 0.25% of Al, and the balance of Fe. The production process comprises the following steps: smelting molten steel, continuous casting, hot-rolling, punching and annealing, and specifically comprises the following steps: pretreating molten iron, smelting in a rotary furnace, blowing argon over the whole process, conducting RH (Rockwell Hardness) fine smelting, conducting CSP (Cast Steel Plate) continuous casting, putting in a CSP heating furnace, conducting CSP hot-continuous-casting, pickling and cold-rolling and annealing, wherein in the smelting process in the rotary furnace, silicon iron, ferromanganese iron and an aluminum alloy are added to conduct alloying so as to manufacture an alloy steel. The semi-process cold-rolling non-oriented electrical steel is mainly used in a production process of a motor iron core.
