In the paper, it is introduced the ultra fast cooling production process 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 ferrite grain became finer and tensile strength increased with the finish rolling temperature decreased; ferrite grain became finer and tensile strength decreased with the medium temperature decreased; the reasonable process parameters were obtained that with the finish rolling temperature of 840 ℃, medium temperature of 670 ℃ and coiling temperature of 170 ℃, the 540 MPa grade hot-rolled dual phase steel with thickness of 6.0 mm produced was with the microstructure of ferrite and martensite, yield strength of 330~360 MPa, tensile strength of 560~590 MPa and elongation of 30%~36%, which met the product requirements very well.
