The invention discloses an automatic-flowing quick-
drying pouring material for a
blast furnace iron runner. The automatic-flowing quick-
drying pouring material is composed of the following main raw materials in percentage by weight: 65-70% of dense
corundum, 14-18% of
black silicon carbide, 3-7% of
silicon nitride, 1-2% of a composite water-reducing admixture, 1-2% of a compound anti-blasting material, 1-3% of pure
aluminum silicate cement, 1-3% of ultrafine silica
powder, 2-4% of reactive
alumina micro
powder and 2-4% of silica
powder. The preparation method comprises the following steps: adding various raw materials into a mixing reactor with a powerful stirring
propeller for performing strong stirring, and packaging after stirring, thereby obtaining the product, namely the automatic-flowing quick-
drying pouring material for the
blast furnace iron runner. The product disclosed by the invention has the advantages of being resistant to
corrosion of molten iron and
slag, high in erosionresistance, excellent in
thermal shock resistance, excellent in flaking resistance, high in
oxidation resistance, easy in construction, capable of performing rapid baking without burst and preventingproduction of harmful gases and adhesion of iron
slag, and long in service life, and the like.
