| Abstract: | The production process of hot rolled dual phase (DP) steels with ultra fast cooling was investigated. The design rule of air cooling temperature/time, coiling temperature and rolling speed was introduced under stepped cooling mode. The reference values of each parameter was obtained using simulation calculation and based on the phase transformation theory. This process was applied on site and DP steel obtains the good properties with tensile strength of 700MPa. |
