Abstract
PURPOSE:To obtain the titled refractory capable of remarkably prolonging the service life of a steel making furnace, having a low coefft. of thermal expansion and suppressing exfoliation and wear when used as lining brick, by adding coarse Al granules of a prescribed diameter to a starting material mixture for a refractory consisting of a fireproof starting material and a carbonaceous starting material. CONSTITUTION:0.5-15pts.wt. coarse Al granules (A) of 0.5-10mm diameter are added to 100pts.wt. starting material mixture for a refractory consisting of 30-97wt.% fireproof starting material (B) such as magnesia, calcia, dolomite, spinel, alumina, SiC or Si3N4 and 70-3wt.% carbonaceous starting material (C) such as flake graphite, coke, carbon black or kish graphite. They are mixed and the resulting mixture is kneaded with a binder such as coal tar pitch or phenol resin, molded and treated at <=600 deg.C to obtain the titled refractory contg. an easily oxidizable substance.
