Abstract: The invention concerns a melting furnace for the melting of mineral fibre raw material which furnace comprises a bottom part (1), sidewalls (2) and a cover (3), and supply means for the raw material. The melting furnace is provided with a discharge opening (4) in the sidewall (2) for mineral melt (8) at a distance from the bottom part (2) of the melting furnace, and a discharge opening (6) for emptying the melting furnace, at the level of the bottom part (2). The melting furnace further comprises an additional discharge opening (7) for discharging of iron melt (11) formed during the melting process provided in the sidewall (2) at a level above the discharge opening (6) for emptying the melting furnace, but at a level below the discharge opening (4) for the mineral melt (8).

Abstract: The invention relates to a method and to an apparatus for the continuous manufacture of a mineral fibre felt. The apparatus comprises a melting furnace (1), means (4) for introducing raw material into the furnace, and a discharge outlet (5) for the mineral melt in form of a melt flow, a device (6) for producing fibres from the melt, and means (8, 9) for collecting these fibres to a fibre felt (7). The apparatus further comprises a device (11) for measuring a parameter of the fibre felt (7) which depends on the melt flow, or for measuring the mass flow through the fiberizing apparatus, a control device (P) where these measured values are compared with set values for the same parameters, and a device, controlled by the control device (P), for regulating the melt flow by e.g. regulating the size of the melt outlet (5) on the basis of the difference between the measured values and the set values of the said parameters.

Abstract: The invention concerns a method for lining the side wall in a melting furnace for melting of mineral fibre raw materials. The side wall carries a lining layer (4) of a rammed refractory material, whereby the lining layer (4) is applied by using a self-sacrificial mould wall (5) therefor, which protects the lining while the rammed material sinters to reach its final hardness.
