REFRACTORY CONCRETE PASTE FOR STRUCTURAL UNIT COMPONENT LINING Russian patent published in 2008 - IPC C04B28/06 C04B35/10 C04B35/66 

FIELD: metallurgy.

SUBSTANCE: invention may be used in the ferrous metallurgy, for the manufacture of gasodynamic cutoffs of electric furnaces, burner units, pyrometer units, blocks for lining of working space of soaking pits, industrial ladle lids, and other linings. The refractory concrete paste for the manufacture of linings for structural components of units contains, % weight: aluminous stock-slag, grades 0-14 mm, with Al₂O₃ contents of no less than 70%, 65-73, high-alumina cement 20-30, powdered lignosulphonate plasticiser 0.1-0.2, cyclone corundum dust with particle size of less than 1 mcm up to 0.05, high-alumina waste lining, grades 0-20 mm, with Al₂O₃ contents of no less than 90%, up to 3.

EFFECT: increased resistance of lining of structural components and decreased power consumption due to elimination of product drying.
