| Abstract: | The production flowsheet of 240 mm slab of tested steel 1500MS (/% : 0.20C, 0.31Si, 1.39Mn, 0.011P, 0.001S, 0.028Als, 0.26Cr, 0.028Ti, 0.0018B, 0.0048N) is 250t BOF-LF-RH-slab CC process. The mechanical properties of tested steel at 1350 ~600°C have been measured by using Gleeble-1500 thermal simulation machine to get I-bnttle zone at 1350 ~ 1250°C , and Ⅲ-brittle zone at 650〜750°C，and at 800〜1200 °C the tested steel has better hot plasticity ； and the mathematical model of slab solidification heat transfer is established and the surface temperature of casting slab in solidification process is calculated. The temperature of tested steel of steel 1500MS at straightening zone should be controlled at 800〜1150°C. |
