ABSTRACT:
A composite brick is proposed which is produced by integrally molding two kinds of bodies, a magnesia-carbonaceous refractory and a basic refractory. These two bodies are put into respective positions in a metal case partitioned by a plate and subjected to pressure molding into a compact brick unit. This composite brick is much less expensive than the conventional high-purity magnesia-carbonaceous bricks. This means a substantial saving in the manufacturing cost of a furnace.
