MAGNESIA MASS FOR LINING METALLURGICAL AGGREGATES Russian patent published in 2007 - IPC C04B35/66 C04B35/04 C04B35/43 

FIELD: refractory article producing industry, possibly manufacture and restoration of linings of high-temperature aggregates in ferrous and non-ferrous metallurgy.

SUBSTANCE: mass used for making and repairing linings of metallurgical aggregates with operation temperature up to 1650°C contains, mass %: magnesia filler with fraction size less than 2 mm as base; inorganic binder, 3 - 10; fibrous material having organic and inorganic fibers taken at relation 1 : (1.5 - 2.5), 1 - 5; mixture of antioxidant, carbon-containing material and refractory plasticizer taken at relation (1 - 2):( 2 - 4): (1 - 5) respectively, 4 - 20.

EFFECT: improved resistance against melt metals and slag, reduced heat conductance, good adhesion with aggregate lining at applying mass, at heating it and at using aggregates.
