REFRACTORY MASS Russian patent published in 2000 - IPC

FIELD: foundry and production of refractories; applicable in mechanical engineering and metallurgy. SUBSTANCE: refractory mass consists of, wt%: fireclay 48.06; refractory clay 51.916; boric acid 0.024. Mineralogical composition of main members of fired refractory products is as follows, wt%: Al₂O₃ 28; SiO₂ 48.61; B₂O₃ 0.028. EFFECT: higher efficiency of claimed refractory mass due to lower baking temperature of refractory products from claimed refractory mass, their increased resistance to slag effect (by a factor of 1.5-2), higher mechanical characteristics. 1 tbl
