Abstract

Procédé pour augmenter la cinétique d'élimination des produits du type huile déposés sur la surface d'un produit métallurgique traversant une zone à température supérieure à 500°C d'un four dont une partie au moins de l'énergie est apportée à laide d'au moins un brûleur alimenté en comburant et en combustible. Selon l'invention, le comburant utilisé par l'un au moins des brûleurs comporte plus de 21 % vol. d'oxygène, de manière à augmenter la concentration en vapeur d'eau dans la flamme ainsi engendrée par rapport à la concentration en vapeur engendrée par le même procédé de combustion qui utiliserait un comburant contenant 21 % vol. d'oxygène au moins, toutes choses égales par ailleurs. De préférence, le traitement s'applique aux tôles d'acier avant galvanisation et le comburant est de l'oxygène pur (contenant plus de 88 % d'oxygène)
