Abstract

Procedure for the preparation of molded and non-molded refractory products and/or articles, suitable to be used for vaults and furnace walls in general, characterized by comprising the use of the following mixture; a) Silico-aluminous or aluminous granular refractory material, with a percentage of alumina between 30 and 95%, present in the mixture in a percentage between 50 and 95%; b) cast aluminous cement in a percentage between 2 and 50%, c) a first additive capable of increasing the resistance of the final material in the temperature range between 300 and 1350ºC, said additive being formed by one or more of the following compounds : sodium aluminates, calcium phosphate, calcium phosphate, sodium phosphate, sodium pyrophosphate (Na4P2O7), sodium silicate (with Na2O/SiO2 ratio between 1 and 3), sodium polyphosphate (Na2O). (NaPO3) n, orthosilicate magnesium, magnesium metasilicate, sodium borate and the like in a total percentage between 1 and 15% d) a second additive capable of ensuring the final material an increase in resistance to thermal jumps, said additive being made up of one or more of the following compounds: silicon boride, sodium tungstenate, phosphoric acid, lithium silicate, lithium fluoride, citric acid and its esters, general aliphatic acids, ammonium citrate, magnesium oxide, and the like; in a total percentage between 1 and 15%; e) water in a percentage between 5 and 20% with respect to the total amount of the aforementioned compounds in which the mixture thus obtained is poured into formwork or in waterproof molds, and then it is vibrated and dried up to 500ºC.
