Title (EN) METHOD OF OPERATING A TOP SUBMERGED LANCE FURNACE
(FR) PROCÉDÉ DE COMMANDE D'UN FOUR À LANCE IMMERGÉE PAR LE HAUT
Abstract:
(EN) TH!S invention relates to a method of operating a top submerged Iance furnace, and more particularly but not exclusively to a method of coating an end of a Iance of a top submerged lance furnace with a slag layer, as well as a method of maintaining a uniform heat distribution about the periphery of the lance of the top submerged Iance furnace. In terms of the method, the Iance is caused to rotate, and a fluid is passed through the lance before it is inserted into the molten material bath inside the crucible.
(FR) Cette invention concerne un procédé de commande d'un four à lance immergée par le haut, et plus particulièrement, mais non exclusivement, un procédé de revêtement d'une extrémité d'un lance d'un four à lance immergée par le haut par une couche de scories, ainsi qu'un procédé permettant de maintenir une répartition uniforme de la chaleur sur la périphérie du four à lance immergée par le haut. En ce qui concerne le procédé, la lance est entraînée en rotation et un fluide est introduit à travers la lance avant son insertion dans le bain de matériau en fusion à l'intérieur du creuset.
