The invention discloses a temperature control method adopted during galvanization through transition of CQ steel to DP steel. The temperature control method comprises an annealing process and a galvanization process. In the annealing process, according to the annealing process of controlling the CQ steel, a first heating section ranges from 660 DEG C to 690 DEG C, a second heating section ranges from 740 DEG C to 780 DEG C, a soaking section ranges from 750 DEG C to 790 DEG C, and the slow cooling finish temperature ranges from 665 DEG C to 695 DEG C. According to the method, temperature increasing caused by the surface gray level of strip steel in the process of transiting the CQ steel to the DP steel is controlled, the temperature of the CQ steel is reasonably controlled, through the production temperature of reasonable transition to the DP steel, stable temperature is obtained, and temperature fluctuation is controlled within the range of 5 DEG C; and the overall coil performance hit rate of dual-phase steel is guaranteed, and the bending performance and the subsequent punching process of the strip steel can be improved easily. According to the method, the temperature of the strip steel is properly reduced through the CQ steel, after the dual-phase steel enters the heating sections and the soaking section of an annealing furnace, the temperature is increased, the annealing temperature for producing the dual-phase steel is achieved, and the same-coil performance stability is guaranteed.
