Abstract

LE PROCEDE EST DU TYPE DANS LEQUEL, AU COURS D'UNE OPERATION DE COULEE CONTINUE DE METAL, ON EFFECTUE SUR LE BRIN COULE UNE OPERATION DE REFROIDISSEMENT SECONDAIRE, REGULEE DE FACON A MAINTENIR UN PROFIL THERMIQUE PREDETERMINE. LE PROCEDE EST CARACTERISE EN CE QUE L'ON CALCULE LA TEMPERATURE SUPERFICIELLE DU LINGOT AU POINT DE REDRESSEMENT, L'ON DETERMINE, PAR UN CALCUL ANTICIPATIF, QUELLE SERAIT LA NOUVELLE TEMPERATURE SUPERFICIELLE PROBABLE DU LINGOT AU POINT DE REDRESSEMENT, L'ON COMPARE CETTE DERNIERE TEMPERATURE AVEC LES VALEURS DE CONSIGNE ET ON DETERMINE PAR LE CALCUL UN NOUVEAU PROFIL THERMIQUE CONDUISANT A LA TEMPERATURE DESIREE AU POINT DE REDRESSEMENT, L'ON AJUSTE LE REFROIDISSEMENT SECONDAIRE, POUR REALISER LE PROFIL THERMIQUE AINSI MODIFIE. APPLICATION A LA COULEE CONTINUE.THE PROCESS IS OF THE TYPE IN WHICH, DURING A CONTINUOUS METAL CASTING OPERATION, A SECONDARY COOLING OPERATION IS PERFORMED ON THE CAST STRAND, REGULATED SO AS TO MAINTAIN A PREDETERMINED THERMAL PROFILE. THE PROCESS IS CHARACTERIZED IN THAT WE CALCULATE THE SURFACE TEMPERATURE OF THE INGOT AT THE RIGHTENING POINT, WE DETERMINE, BY AN ANTICIPATIVE CALCULATION, WHAT WOULD BE THE NEW PROBABLE SURFACE TEMPERATURE OF THE INGOT AT THE RIGHTENING POINT, WE COMPARE LAST TEMPERATURE WITH THE SETPOINT VALUES AND A NEW THERMAL PROFILE IS DETERMINED BY CALCULATION LEADING TO THE DESIRED TEMPERATURE AT THE SETTING POINT, THE SECONDARY COOLING IS ADJUSTED TO ACHIEVE THE THERMAL PROFILE THUS MODIFIED. CONTINUOUS CASTING APPLICATION.
