Major iron runner casting material for blast furnace
The present invention relates to a major iron runner casting material for a blast furnace, belongs to the field of refractory casting materials, and comprises the following components in parts by weight: 5-8 parts of 8-5mm chromium nitride, 15-20 parts of 5-3mm zirconium corundum, 10-15 parts of 3-1mm sillimanite, 8-15 parts of 1-0mm calcium chromate, 2-5 parts 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 composite carbon powder, 0-3 parts of molybdenum trioxide powder, 3-5 parts of aluminium oxide micro powder, 1-5 parts of magnesium iron oxide powder, 1-3 parts of rho-aluminium oxide and 0-5 parts of electric smelting pure calcium aluminate cement. Based on the total weight by parts of the main materials: 100%, the additives comprise the following components in parts by weight: 0.1-0.2 part of lignin calcium sulfonate, 0.01-0.05 part of nano potato powder, 0.01 part of malic acid and 20:1 parts of C12H14N4O5S. The iron runner for the blast furnace made of the casting material has the characteristics of good thermal shock resistance, high corrosion resistance, large iron influx and long service life.
