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.
