CARBON-CONTAINING REFRACTORY Russian patent published in 1998 - IPC

FIELD: manufacture of refractory materials, more particularly manufacture of linings of metal-working units. SUBSTANCE: carbon- containing refractory is prepared form compound which comprises, wt.%: granular refractory filler such as fired 65-68% Al₂O₃ containing bauxite, 50-85; carbon- containing component, 5-20; finely divided component with particle size of less than 0.0063 mm selected from group consisting of fired bauxite and/or periglase, and/or corundum, and/or alumomagnesium spinel, 10-30; organic binder (more than 100 %) containing mixture of powder-like phenol binder with ethylene glycol at (1.76- 2):1 ratio, 3-8. Material also comprises antioxidant in the form of oxygen-free titanium and/or aluminium, and/or magnesium, and/or chromium compounds in amount of 0.5-3 wt %. Use of the claimed composition makes it possible to mold refractories with especially dense and strong structure. EFFECT: improved properties of the carbon- containing refractory. 2 cl, 2 tbl
