The invention discloses a rolling pressure setting method of precision rolling phase-change strip steel; and a formula for calculating the impact of temperature on deformation strength is set up by considering the volume fraction of rolled piece austenitic deformation and ferrite deformation, so that the rolling pressure setting precision of phase-change strip steel in a two-phase area and a ferrite area is significantly improved, and the purposes of improving the strip steel thickness control precision and production stability are achieved. According to the technical scheme, because a phase-change volume fraction calculation model in a cosine form and a deformation strength impact calculation formula in a weighted form are adopted in the double-phase area, the deformation characteristic of a rolled piece in the double-phase area can be better simulated, so that the matching with an actual rolling result is very high.
