The invention discloses a production method for a cold rolling dual-phase steel base plate. The production method includes the steel-making and casting step, the heating step, the hot rolling step and the cooling step. The cooling step is in a three-section cooling manner, wherein strip steel is firstly subject to first-time forced cooling and is cooled to 700 DEG C to 740 DEG C; then air cooling is carried out for 1.5 s to 3 s within the temperature range; and the strip steel obtained after air cooling is subject to second-time forced cooling to 620 DEG C to 690 DEG C for reeling, U-shaped control is adopted for reeling, in other words, the temperature used when 20 m to 30 m of the strip steel from the head is reeled is 10 DEG C to 30 DEG C higher than the temperature used when the middle portion of the strip steel is reeled, and the temperature used when 40 m to 80 m of the strip steel to the tail is reeled is 20 DEG C to 40 DEG C higher than the temperature used when the middle portion of the strip steel is reeled. According to the method, at the temperature close to the austenite transformation Curie temperature, the slow cooling process is adopted, ferritic structures are homogenized, and the precipitation proportion of pearlites is controlled; compared with a conventional production process, the uniformity of the structures and the performance is facilitated; and through mechanics property analysis in the hot rolling pass length direction, the strength property fluctuation is smaller than 20 MPa, and the products meet the using requirements of a next working procedure.
