APPLICATION OF REFRACTORY MATERIAL ON BASE OF MAGNESITE AND ZIRCONIUM DIOXIDE IN REGENERATIVE BATHS OF GLASSMAKING FURNACES

摘要

FIELD: refractory materials for regenerative baths of glassmaking furnaces.;SUBSTANCE: proposed refractory material on base of magnesite and zirconium dioxide contains ZrO₂ in the amount of 5 to 35 mass-% and MgO in the amount of 65 to 95 mass-% and other components in the amount of maximum 5 mass-% and SiO₂ in the amount lesser than 1.0 mass-%; during operation of glassmaking furnace, reducing atmosphere is periodically created and maintained.;EFFECT: possibility of keeping regenerator lining intact.;6 cl, 1 tbl
