Abstract
Ved en fremangsmåte for skumning av materiale (2), spesielt slagg eller glass, hvor materialet (2) oppskummes direkte i smeltet tilstand ved anvendelse av et skumningsmiddel (3), blir det smeltede materi- ale (2) og et pulverformet skumningsmiddel (3) tilført et drei- og/eller svingbart behandlingskar (1), fortrinnsvis en rotasjonsrørovn. Skumningsmid- delet (3) blir fordelt på overflaten, og kun ved bevegelse av behandlingskaret (1) blandet intensivt med det flytende materiale (2) . Materialet (2) oppskummes på grunn av gassutvikling og føres deret- ter ut av behandlingskaret (1) som oppskummet produkt (11), og avkjøles. Det på denne måte oppskummede produkt (11) inneholder meget fint fordelte, lukkede porer og vil derfor være godt anvendelig som bygge- eller isolasjonsmateriale.In a foaming method of material (2), especially slag or glass, where the material (2) is foamed directly in the molten state using a foaming agent (3), the molten material (2) and a powdered foaming agent (3) ) supplied with a rotatable and / or pivotable treatment vessel (1), preferably a rotary tube furnace. The foaming agent (3) is distributed on the surface and only intensively mixed with the liquid material (2) upon movement of the treatment vessel (1). The material (2) is foamed due to gas evolution and then discharged from the treatment vessel (1) as foamed product (11) and cooled. The foamed product (11) in this way contains very finely spaced, closed pores and will therefore be well usable as building or insulating material.
