Abstract: Temperature field under ultra fast cooling (UFC) is simulated by finite-difference method. The results show that when a slab which was rolled from 180 mm to 40 mm by 6 passes at an initial temperature 1200°C enters into a UFC zone standing between the roughing mill and finishing mill at 3 m/s, a water cooling rate 70°/s can be obtained if the heat-exchange coefficient is up to 10 kW/(m2·°C). At the same time, the entrance finishing temperature must be corrected because of the strong temperature recovery after UFC.
