METHOD FOR FORMING CASTABLE REFRACTORY BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a castable refractory block which has a uniform pore distribution and is suitable for the constitution of a highly durable mass block, a plug for gas blasting, and others. SOLUTION: A method for forming a castable refractory block has a process in which a kneaded castable refractory 3 is cast into a porous molding mold 2 in which an average pore diameter on side of the inner wall surface is 1-30 μm and a process in which the pores of the mold 2 are evacuated and vibrated so that the cast refractory 3 is packed enough to be a block. The porous mold 2 is preferably made of a synthetic resin or a ceramic.
