Cold bonded pellet obtained by using TiO2 fine ores

摘要

PURPOSE: Provided are non-plastic pellets with high strength recycled to blast furnace by mixing corex sludge generated from steelmaking industry with powdered TiO2 ore. CONSTITUTION: The high strength non-plastic pellets contain 25-30wt.% of sintered R-EP dust, 25-30wt.% of rolled incineration ash, 25-30wt.% of corex sludge, 5-10wt.% of powdered TiO2 ore with a size less than 2mm, and 8-12wt.% of cement(portland cement) as an inorganic binder.
