ABSTRACT:
The invention relates to a method for manufacturing heat-resistant and/or fire-resistant fibre materials, when the employed initial material is molten slag from metal processes. According to the invention, the slag holding furnace (5) is used for achieving an essentially even and continuous molten flow from the slag smelting furnace (3) into the mineral wool furnace (6). The invention also relates to an apparatus for realizing the method, wherein the holding furnace (5) is provided with at least one control device (12) which shifts the furnace (5) between the different filling positions in order to ensure an even and continuous flow of molten material.
