Miniature type blast furnace branch iron runner castable
The invention relates to a miniature type blast furnace branch iron runner castable, and belongs to the field of refractory castables. The miniature type blast furnace branch iron runner castable comprises the following components in parts by weight: 5-8 parts of 8-5mm plate-like corundum, 15-20 parts of 5-3mm chromium nitride, 10-15 parts of 3-1mm sillimanite, 8-15 parts of 1-0mm chromite calcium, 2-5 parts of partial clay powder, 3-7 parts of cobalt oxide aluminum powder, 5-10 parts of cutting powder, 3-8 parts of amorphous graphite powder, 1-2 parts of composite carbon powder, 0-3 parts of molybdenum trioxide powder, 3-5 parts of aluminum oxide micro powder, 1-5 parts of magnesium oxide iron powder, 1-3 parts of rho aluminum oxide, and 0-5 parts of electric smelting pure calcium aluminate cement; the percentage by weight of an additive is 100% according to the total percentage in percentages by weight of main materials, and the additive comprises the following components in parts by weight: 0.1-0.2 part of calcium ligninsulfonate, 0.01-0.05 part of nanometer dried potato powder, 0.01 part of malic acid and 0.1 part of C12H14N4O5S2. A blast furnace branch iron runner manufactured by the castable has the characteristics of high thermal shock resistance, high erosion resistance, large iron flux and long service life.
