METHOD OF REFRACTORY COATING PREPARING ON THE HOT SURFACE AND POWDERY MIXTURE FOR REFRACTORY COATING PREPARING Russian patent published in 1995 - IPC

FIELD: porous refractory mass, powdery mixture. SUBSTANCE: method involves the feeding of exothermic powdery mixture on the hot surface by oxygen flow. Powdery mixture has at least one fuel component from the group: silicon, aluminium, magnesium, zirconium, at least 5 wt.-% pore-forming component, silicon oxide and/or aluminium oxide. Source of pore-forming component: burning out carbon-containing material, swelling material, porous silicon oxide and/or cellular aluminium oxide, and glass microspheres also. Material is used for repair of heat-insulating lining. EFFECT: improved method of material preparing. 12 cl, 1 tbl
