Title (EN) WOODEN CASING FOR OXYGEN LANCES
(FR) BOÎTIER EN BOIS POUR LANCES À OXYGÈNE
Abstract:
(EN) The present invention provides an oxygen lance having a wooden casing, a process for production of silicon metal or metal alloy in an arc furnace, wherein liquid silicon metal or metal alloy is produced and the liquid metal or metal alloy is removed from the furnace through a tap hole, wherein the tap hole is opened by an oxygen lance having a wooden casing and a process for melting of slag in an arc furnace, wherein liquid slag is removed from the furnace through a tap hole, wherein the tap hole is opened by an oxygen lance having a wooden casing.
(FR) La présente invention concerne une lance à oxygène ayant un boîtier en bois, un procédé de production d'un métal de silicium ou d'un alliage métallique dans un four à arc, le métal de silicium liquide ou l'alliage métallique liquide étant produit et le métal liquide ou l'alliage métallique liquide étant retiré du four à travers un trou de coulée, le trou de coulée étant ouvert par une lance à oxygène ayant un boîtier en bois et un procédé de fusion de laitier dans un four à arc, le laitier liquide étant retiré du four par l'intermédiaire d'un trou de coulée, le trou de coulée étant ouvert par une lance à oxygène ayant un boîtier en bois.
