BINDER FOR GRAPHITE-CONTAINING MONOLITHIC REFRACTORY AND GRAPHITE-CONTAINING MONOLITHIC REFRACTORY USING THE BINDER

摘要

PROBLEM TO BE SOLVED: To obtain a binder for graphite-containing monolithic refractories which has no reduction of strength in all temperature regions from ordinary temperatures to hot temperatures, and can hot-form a bond with graphite, and graphite-containing monolithic refractories using the binder.;SOLUTION: (1) The binder for graphite-containing monolithic refractories contains resin, pitch and metal (Si and/or Al) powder as the main components, and in which the mass ratio of the total content of the pitch and resin to the total content of the pitch, resin and metal powder is 0.6 to 0.9. (2) The graphite- containing monolithic refractories are obtained by mixing the binder for graphite-containing monolithic refractories of the (1) into a refractory material containing a refractory filler and graphite powder as the main components. The total solid content in the refractories contains ≤1.5 mass% alumina cement and 0.1 to 1 mass% resin.;COPYRIGHT: (C)2002,JPO
