Abstract

L'invention vise à corriger ou à limiter la déformation en losange de la section de billettes ou de blooms dans la zone de refroidissement secondaire. Selon l'invention, on détecte les écarts éventuels par rapport à la section rectangulaire voulue de la barre 12 et on module le refroidissement par les rangées de tuyères d'aspersion 7 à 10, en fonction des écarts, par l'augmentation du débit d'eau des rangées de tuyères 7 et 10 arrosant les angles obtus et la diminution du débit des rangées de tuyères 8 et 9 qui arrosent les angles aigus de la barre 12.The invention aims to correct or limit the diamond-shaped deformation of the section of billets or blooms in the secondary cooling zone. According to the invention, any deviations from the desired rectangular section of the bar 12 are detected and the cooling is modulated by the rows of spray nozzles 7 to 10, depending on the deviations, by increasing the flow rate d 'water from the rows of nozzles 7 and 10 spraying the obtuse angles and the reduction in the flow rate from the rows of nozzles 8 and 9 which spray the acute angles of the bar 12.
