主 题：billet continuous casting secondary cooling water models billet quality
摘 要：The continuous casting process is used for solidifying molten steel into semi-finished *** technology of secondary cooling is extremely important for output of the casting machine and billet quality.A dynamic water model was introduced,including solidification model in the secondary cooling,feedforward control strategy based on continuous temperature measurement in tundish,and feedback control strategy based on surface temperature *** mathematical model of solidification process was developed according to the principle of solidification,and the solidification model was validated by measuring billet shell thickness through shooting nail and sulfur *** water distribution was calculated by the solidification model according to procedure parameters,and it was adjusted by the other two control strategies *** model was applied on some caster and billet quality was obviously improved,indicating that the dynamic water model is better than conventional ones.
