FIELD: manufacture of refractory products for continuous casting of steel.
SUBSTANCE: built up refractory product for casting metal includes at least two parts made of different composition charges. One part in the form of separate porous member is permeable for gas. Said porous part is made of charge containing, mass. %: melt corundum with fraction size 0.5 - 0.2, 89.4 - 93.1; reactive alumina, 4.8 - 6.9; chrome-aluminum phosphate binder, 1.9 - 3.9.
EFFECT: increased gas permeability of porous member.
