Casting material for 800m<3> blast-furnace branch iron trough
The invention relates to a casting material for a 800m<3> blast-furnace branch iron trough. The casting material comprises a main material and an additive, wherein the main material comprises the following components in parts by weight: 5-8 parts of 8-5mm magnesium silicate, 15-20 parts of 5-3mm chromium nitride, 10-15 parts of 3-1mm sillimanite, 8-15 parts of 1-0mm calcium chromite, 2-5 parts of slightly-viscous clay powder, 3-7 parts of cobalt-aluminum oxide powder, 5-10 parts of cutting powder, 3-8 parts of amorphous graphite powder, 1-2 parts of compound carbon powder, 0-3 parts of molybdenum trioxide powder, 3-5 parts of aluminium oxide micropowder, 1-5 parts of magnesium-iron oxide powder, 1-3 parts of Rho aluminium oxide and 0-5 parts of electrically-smelted pure calcium aluminate cement; the additive comprises the following components in parts by weight according to the total weight part 100% of the main material: 0.1-0.2 part of calcium lignosulphonate, 0.01-0.05 part of nano potato powder, 0.01 part of malic acid and 0.1 part of C12H14N4O5S2. The blast-furnace iron trough prepared by the casting material has the characteristics of good thermal shock resistance, strong anti-erosion performance, large iron influx and long service life.
