Abstract:
(EN) A shield device for occluding a tap hole of a furnace, said shield device comprising: an elongate shaft (400); a shield member (403) attached to said elongate shaft and extending transverse to a main length of said elongate shaft; and a retaining means (405) spaced apart from said shield member along a length of said shaft, for retaining at least a portion of said elongate shaft in a tap channel of said furnace.In use, the shield device is inserted mechanically into the tap hole from a position inside the furnace. The shield the device is removed via the tap hole as molten metal, by melting the shield device when it comes into contact with molten metal inside the furnace.
(FR) Cette invention concerne un dispositif de protection pour obturer un trou de coulée d'un four, ledit dispositif de protection comprenant : une tige allongée (400) ; un élément de protection (403) fixé à ladite tige allongée et s'étendant transversalement à une longueur principale de ladite tige allongée ; et des moyens de retenue (405) espacés dudit élément de protection sur une longueur dudit arbre, pour retenir au moins une partie dudit arbre allongé dans un canal de coulée dudit four. Lord de l'utilisation, le dispositif de protection est inséré mécaniquement dans le trou de coulée à partir d'une position à l'intérieur du four. Le dispositif de protection est retiré par le trou de coulée sous forme de métal fondu, par fusion du dispositif de protection lorsqu'il entre en contact avec le métal fondu à l'intérieur du four.
