FIELD: refractory industry, in particular manufacturing of refractory material for cladding of steel teeming ladles.
SUBSTANCE: claimed refractory material is obtained from refractory mass containing (mass %): <0.063 mm-grade corundum 16-20; 0.5-1.0 mm-grade periclase 4-12; graphite 6-10; metal aluminum 1-5; crystalline silicium 2-5; ethylene glycol 1.5-1.8; powdered phenol binder containing not more than 1.0 mass % of free phenol 2.7-3.3; and balance: 0.5-6 mm-grade corundum. Abovementioned <0.063 mm-grade corundum contains <0.020 mm grade in amount of 1-5 mass % or more based on total corundum mass.
EFFECT: refractory material with bulk stability, high mechanical strength and low oxidation susceptibility.
