FIELD: chemistry.
SUBSTANCE: high-aluminous refractory is obtained from a mass including crystal quartzite, alumina, calcium and iron oxides, commercial lignosulfate and bauxite fraction of 1-3 mm size with silicon module not less than 10 and total titanium and iron oxide content under 6.5 wt %, at the following component ratio, wt %: alumina 40-50, given bauxite 10-20, calcium oxide 0.8-1.6, iron oxide 0.7-1.4, commercial lignosulfate (in dry weight) 1.5-2.5, the rest is crystal quartzite.
EFFECT: increased volume maintenance of refractory and higher initial deformation temperature under stress.
