REFRACTORY MIXTURE FOR LINING AND REPAIR WORKS OF THERMAL UNITS Russian patent published in 2024 - IPC C04B35/47 C04B35/66 

FIELD: refractory mixtures.

SUBSTANCE: invention relates to production of refractory mixture, which can be used as masonry mortar and for coating during lining and repair works of thermal units. Refractory mixture contains chromite ore, iron oxide, magnesium sulphate or aluminium sulphate, periclase, as well as aluminium or an alloy of aluminium and silicon, and additionally contains a silicate lump used as flux, in the following ratio, wt.%: chromite ore 44.0–66.4, iron oxide 10.0–21.0, aluminium or aluminium and silicon alloy 9.0–15.0, periclase 5.0–10.0, magnesium sulphate or aluminium sulphate 7.0–15.0, silicate lump 0.5–1.0.

EFFECT: obtained mixture composition enables to reduce ignition temperature to values of 710–750 °C and has refractoriness of 1,680–1,770 °C.
