BLEND FOR PREPARING REFRACTORIES Russian patent published in 2002 - IPC

Abstract RU 2178395 C2

FIELD: metallurgical and building industries and heat engineering. SUBSTANCE: blend comprises, wt. %: alumina, 10-80; silicon carbide, 1-50; spinel and/or clinker, 1-80; ferrosilicon, 3-20; liquid glass, 3-10; and water, 5-15. Ferrosilicon is used in the form of cyclonic dust after crushing ferrosilicon ingot having silicon content of not lower than 75 wt. %. EFFECT: drying time of refractories reduced by 5 or 6 times, elimination of ecologically adverse factors, lower manufacturing cost of refractories. 1 tbl
