Abstract

Magnesite-chrome refractory bricks are made by shaping and firing a mixture of a magnesite refractory passing a 72 mesh sieve (BS) and crushed bricks and pellets of a mixture of chrome ore and magnesia, the latter forming at least 50% by weight of this mixture, which has been pre-fired at 1580-1680 DEG C. Preferably a chrome refractory material is included in the mixture of magnesite and crushed pre-fired bricks in amount of at least 15% and contaniing less than 5% SiO2. Preferably the overall magnesia content of the bricks is not more than 75% by weight.
