In the paper, it is introduced the ultra fast cooling control system suitable for hot-rolled dual phase steel is developed based on the CSP production line with short process and its industrial applications are realized. The results showed that the control of water supply pressure was realized with the pressure closed-loop of power pump and fuzzy PID control of relief valve; the control of flow for header was realized with the fuzzy control of control valve; the tracking of position of strip steel was realized with the accumulation of product of actual speed of strip steel and scan period of program. The cooling rate of hot-rolled strip steel with thickness of 6.0 mm was 190~210 ℃/s, the cooling rate of hot-rolled strip steel with thickness of 11.0 mm was 100~120 ℃/s, the medium temperature was controlled at (670±10)℃ and the coiling temperature was controlled at target value ± 30 ℃, which well met the product requirements.
