Document Type and Number:
Japanese Patent JPH0150833
Kind Code:
B2
Abstract:
An electric melting furnace arrangement for the continuous melting of spinnable mineral fine-particle or granular materials has a refractorily lined furnace vessel, a plurality of electrodes arranged on a partial circle extending into the furnace vessel from above, conveying devices for the materials to be melted designed as dosing pipes arranged close to the partial circle formed by the electrodes and each provided between two electrodes and a tapping device penetrating a side wall of the furnace vessel. Transporting devices are provided for admitting the dosing pipes, and when the dosing pipes are completely full, the further conveying of the materials to be melted is interruptable. In a method of influencing the composition of a mineral melt for producing wool in that electric melting furnace arrangement, iron-oxide-containing materials are used as starting materials and metallic aluminum is added thereto for reducing iron oxide to metallic iron, and the metallic iron collecting on the bottom of the furnace vessel is removed via a further tap.
