REFRACTORY MIXTURE FOR REPAIR AND LINING OF METALLURGICAL UNITS Russian patent published in 2000 - IPC

FIELD: manufacture of refractories applicable in repair and lining of metallurgical units including intermediate ladles, transfer and emergency vessels, etc. SUBSTANCE: refractory mixture includes, wt.%: periclase of 3-1 mm fraction 11-18; of 1-0 mm 60-65; of 0.09 mm 12-21; magnesium sulfate 1.4-2.0; bentonite of 0.5-0 mm fraction 0.7-2.5; burning out additive of 3-0 mm fraction 0.9-3.5; sodium metasilicate 1/8-3/0. Mixture features increased adhesion at moment of its application to surface of permanent lining being at angle of 70-90 deg to horizontal that prevents rebound and separation of lining, both, during its application and drying, and higher corrosion resistance of claimed mixture. EFFECT: higher quality and operating characteristics of mixture. 1 tbl
