摘要:
Method and device for manufacturing siliceous melts to produce light-yellow mineral wool fibres using a cupola furnace includes (a) a charge including at least two different types of briquet, wherein chemical components take into account an anticipated proportion of iron, (b) the components of Al2O3 in the briquets are a supporting structure for the melting process, (c) a plurality of high temperature gas burners for heating, an arrangement of said gas burners chosen such that the burner flames reinforce each other, (d) collecting pan flared conically downwards from a mantle of a shaft in the furnace to a floor of the furnace.
