| Abstract: | The static continuous cooling transformation curve(CCT curve) of SKS51 steel was established by the expansion method,and cooling control process of SKS51 steel was studied in thin slab casting and direct rolling process.The results show that: coiling temperature is the main factors of controlling the cooling process that affects microstructure and performance of SKS51 steel.The reasonable coiling temperature of SKS51 steel is 590(Bs point) ~610 ℃ so that microstructure is main pearlite,does not contain bainite and network cementite,and strength and hardness are moderate,plasticity is good. |
