FIELD: metallurgy.
SUBSTANCE: investment contains, wt %: 9.99-72.80 of quartz-bearing component with containing of SiO2 not less than 96 wt % and grain size 0.1-1.0 mm; 14.98-77.67 chromite concentrate and/or chromite ore with content of Cr2O3 not less than 35 wt % and grain size 0.1-1.0 mm; 0.05-9.70 of graphite with grain size less than 0.1 mm; 0.01-2.91 olein and/or stearic acid.
EFFECT: fluidity increasing of investment, density increasing of its stowage into free poured condition, hardening againstk iron-containing melts, probability reduction of mixture sintering ability.
