METHOD OF REFRACTORIES PRODUCTION Russian patent published in 2000 - IPC

FIELD: manufacture of refractories, particularly, methods of manufacture of refractories used for lining of high-temperature units. SUBSTANCE: used for forming is mixture with bulk density of 45-52% of preset density of formed refractory. Forming at stage of preliminary compression up to specific pressure of not in excess of 10 N/sq.mm is effected at speed of not more than 10 mm/s, and forming force at all stages is directed to article faces located in unit brickwork across direction of heat flux. EFFECT: reduced heat conductance of refractory containing solid carbonaceous component in direction of propagation of heat flux in lining. 1 tbl
