The invention relates to refractory industry, namely to the compositions of refractory sealant mass for the production of monolithic linings of heat aggregates with the temperature of work to 1700 °С, particularly of core induction and crucible furnaces. The sealant mass of increased resistant to the slag melt contains, mass %: 54-58 of electromelted corundum of fraction 3-; 34-39 of finely ground alumina mixture with quartziferous additive; 0.5-1.5 of metallurgical chrome oxide with СrОcontent, not less than 98 %, and size of particles less than ; 5.5-7.5 of orthophosphoric acid. |
