Abstract

Suivant ce procédé on prélève du métal en fusion dans un four à une température supérieure à celle nécessaire pour la suite du traitement, on mesure la température du métal en fusion dans la poche et l'on ajoute au métal en poche une quantité prédéterminée de grains de fonte préalablement réduite, cette quantité étant déterminée à partir de la mesure précédente de la température et en tenant compte de la quantité et de la qualité du métal se trouvant dans la poche.According to this process, the molten metal is taken in a furnace at a temperature higher than that required for the rest of the treatment, the temperature of the molten metal in the ladle is measured and a predetermined quantity of grains is added to the ladle metal. of previously reduced cast iron, this quantity being determined from the previous measurement of the temperature and taking into account the quantity and quality of the metal in the ladle.
