Patent

CA 2426847

The present invention relates to a method and a system for the control of a gas-containing hidden flow of molten metal in a space defined by a tubular means. From mesurements in at lest one predetermined layer of the metal flow in teh space, an indication is obtained o fthe appearance of the flow which is compared with stored values. The result of the comparison is used for controlling at least one flow-affecting parameter in such a manner that a desired type of flow is provided at least in said layer.

L'invention concerne un procédé et un système permettant de commander un flux de métal fondu caché et contenant du gaz dans l'espace défini par un moyen tubulaire. Des mesures effectuées dans au moins une couche prédéterminée du flux de métal dans l'espace cité permettent d'obtenir une indication de l'apparence du flux que l'on compare à des valeurs enregistrées. Le résultat de cette comparaison sert à commander au moins un paramètre affectant le flux de manière telle qu'un type de flux souhaité est produit au moins dans cette couche.
