Abstract This invention relates to monolithic castable refractory compositions for lining various smelting furnaces and other industrial furnaces, molten metal containers and the like, and to the preparation of such compositions and the products obtained from them. These compositions comprise the following ingredients: ______________________________________ refractory clay: 3 - 12% by weight
metallic aluminum powder
0.1 - 5.0% by weight
(purity = 90% or higher;
particle size = 0.074 mm
or less for 50% or more
by weight of the aluminum
powder):
deflocculating agent:
0.01-1.0% by weight
coagulant: 1-8% by weight
reaction inhibitor for
to be added optionally
aluminum powder: in a quantity from 0.0
to 0.5% by weight
refractory aggregates
balance
with particle sizes
adjusted:
