Abstract (en)
1. Process for the control of the microstructure of rolled steel products subjected to a controlled cooling from a temperature above their upper transformation point, characterized in that the transformation temperature is determined at at least one point of at least one section of the product, in that the mean transformation temperature of the said section is calculated, in that this calculated value is compared to a set value of the said mean transformation temperature and in that the conditions of the said cooling are modified so as to reduce, preferably to eliminate, the difference found between the calculated value and the set value of the said mean transformation temperature of the section.

Procédé pour le contrôle automatique de la structure des produits en acier laminés, dans lequel on determine la température de transformation en au mains un point d'une section du produit en cours de refroidissement contrôlé, on calcule la température movenne de transformation de la dite section, on compare cette valeur calculée à une valeur de consigne de la dite temperature moyenne de transformation et on modifie les conditions du refroidissement, de façon à réduire, de préference à annuler, l'ecart constaté entre la valeur calculée et la valeur de consigne de la température moyenne de transformation de la section.
