The invention concerns the modification of the thermal profile developed by a product during treatment, in particular in a reheating furnace. The invention is characterised in that it consists in decreasing the treating time of the products, while increasing the available heating power, thereby enabling to reduce the thickness of the decarburized layer and/or the thickness of the calamine layer, hence decreasing melting losses.
L'invention concerne la modification du profil thermique suivi par un produit lors de son traitement, notamment dans un four de réchauffage. Selon l'invention, on diminue le temps de traitement des produits, tout en augmentant la puissance de chauffe disponible, ce qui permet de réduire d'une part l'épaisseur de la couche décarburée et/ou d'autre part, l'épaisseur de la couche de calamine, diminuant ainsi les pertes au feu.
