FIELD: non-iron metallurgy, in particular method for cladding of blast furnace trunks.
SUBSTANCE: claimed refractory mass contains (mass %): silicium carbide 21-28; coal-tar pitch 2-4; calcium aluminate cement 4-6; reactive alumina 5-10; deflocculant 0.8-1.2; water 4.0-4.5, and balance: refractory filler. As deflocculant chemically modified reactive alumina - dispersing alumina is used. As refractory filler mass contains electrocast corundum with fineness of 0-6 mm free from metallic enclosures.
EFFECT: refractory mass with fast hardening after cladding, low porosity, high mechanical fastness, refractory characteristics and good flowability.
