METHOD OF CUTTING REFRACTORY BODY, AND POWDER MIXTURE

摘要

FIELD: refractory materials. SUBSTANCE: powder mixture contains particles of refractory metal oxide and combustion particles, which, when in contact with oxygen, burn down in exothermic reaction to form refractory oxide. Mixture of invention is distinguished by containing calcium oxide jointly with magnesium oxide. EFFECT: enabled more efficient cutting of refractory bodies at lower temperatures and even at ambient temperature. 15 cl, 2 tbl, 2 ex
