Abstract

Inventia se refera la un procedeu de obtinere a vatei de sticla din zguri acide de furnal, constituita din 56...60% SiO2, 0,21...0,25% FeO3, 4...5% Al2O3, 27...29% CaO, 4...5% MgO si 4...5% alcalii, prin care, în scopul îmbunatatirii caracteristicilor fizico-chimice a vatei de sticla, se folosesc, la elaborare sarje constituite din 55...64% zgura granulata, de furnal, 25...35% deseuri de sticla si nisip cuartos rest.The invention relates to a process for obtaining glass wool from blast furnace slags consisting of 56 ... 60% SiO2, 0.21 ... 0.25% FeO3, 4 ... 5% Al2O3, 27. .29% CaO, 4 ... 5% MgO and 4 ... 5% alkali by which, in order to improve the physicochemical characteristics of the glass wool, are used in the elaboration of batch constituted from 55 ... 64 % granular slag slag, 25 ... 35% waste glass and quartz sand rest.
