KNEADED REFRACTORY

摘要

PURPOSE:To provide a monolithic refractory for cast molding previously kneaded with water added used for the wall lining of various molten metal vessels such as a tapping spout, a tundish for a blast furnace. CONSTITUTION:This monolithic refractory is produced by adding and kneading 0.1-3.0pts.wt. aluminum tripolyphosphate hardly soluble in water and 4-10pts.wt. water based on 100pts.wt. monolithic refractory prepared by mixing an alumina cement with an insulating material as a binder. As a result, the refractory causes hydraulic reaction at a relatively low temp. heating after working and is uniformly hardened.
