| description | The present invention relates to a process of producing man-made vitreous fibres having a composition which contains at least 14% aluminium measured as weight Al 2 O 3 based on oxides, comprising
providing in a shaft furnace a self-supporting stack of mineral charge which includes briquettes,
melting the charge to provide a melt at the base of the furnace having the composition of the fibres,
removing melt from the base of the furnace and fiberising the melt,
characterised in that at least one quarter of the aluminium in the charge is introduced as particulate alumina-containing mineral in briquettes and the particulate alumina-containing mineral contains from 0.5 to 10 wt.% metallic aluminium, 50 to 90 wt.% alumina Al 2 O 3 and 0 to 49.5 wt.% other materials. |
