Abstract
The cement-free, castable refractory composition for producing dense cast refractories according to the present invention comprises 70-98 weight % of refractory aggregate regulated to have a particle size of 10 mm or less, 2-30 weight % of ultrafine refractory powder having a particle size of 10 .mu.m or less, and 0.01-1.0 weight % (outer percentage), based on 100 weight % of the refractory aggregate+the ultrafine refractory powder, of a dispersing agent. The cement-free, castable refractory composition tempered with water or other tempering liquids to have a castable flowability or the factory-premixed, cement-free, castable refractory composition is conveyed to a gunning nozzle by a pump, and a coagulant is added to the tempered refractory material together with compressed air in the nozzle to carry out gunning.
