Abstract

Oppfinnelsen vedrører en fremgangsmåte for fremstilling av mineralull, hvor mineralråmateriålet (2) blir innført i en smelteenhet (3), fortrinnsvis en kuppel-. ovn, for oppvarming av mineralråmateriålet på en slik måte at det dannes smeltet mineralmaterlale (4) på smelteenhetens bunn, hvoretter det smeltede mineralmaterialet blir utlevert fra smelteenheten, ytterligere oppvarmet og innført langsmed i det minste en tappe-renne (8,9), inn i en spinnemaskin (10) i hvilken mineralmaterialet blir omvandlet til fiberform. For å gjøre mineralsmelten homogen og for å sikre høy kvalitet på den oppnådde mineralull, er fremgangsmåten ifølge oppfinnelsen særpreget ved at den ytterligere oppvarming utføres ved oppvarming av det smeltede mineralmaterialet (4') ved hjelp av elektrisk plasma, hvilken plasmaoppvarming utføres i tapperennen (9) mens smeltet mineralmaterlale (4') strømmer 1. tapperennen, for således å oppnå en hurtig regulering av temperaturen til det smeltede mineralmaterialet og for å innføre det smeltede mineralmaterialet i spinnemaskinen (10) ved en jevn temperatur.The invention relates to a process for the production of mineral wool, in which the mineral raw material (2) is introduced into a melting unit (3), preferably a dome. furnace, for heating the mineral raw material in such a way that molten mineral material (4) is formed on the bottom of the melting unit, after which the molten mineral material is delivered from the melting unit, further heated and introduced along at least one tapping chute (8,9), into in a spinning machine (10) in which the mineral material is converted into fibrous form. In order to make the mineral melt homogeneous and to ensure high quality of the mineral wool obtained, the method according to the invention is characterized in that the further heating is carried out by heating the molten mineral material (4 ') by means of electric plasma, which plasma heating is carried out in the drain (9 ) while molten mineral material (4 ') flows 1. the drain chute, so as to obtain a rapid regulation of the temperature of the molten mineral material and to introduce the molten mineral material into the spinning machine (10) at a uniform temperature.
