For roasted pellets, calcium additives can form binding phase of calciumferrite, and suitable liquid phase will improve recrystallization of hematite, but excessive liquid will destroy the structure of pellets, so the compressive strength of pellet increases firstly and then drops.
May 08, 2011· Research highlights Effect of pellet basicity and MgO on the formation of different phases during induration was examined. RDI and softeningmelting characteristics of pellets found to be improving with increasing basicity. Addition of MgO to both acid and limestone fluxed pellets considerably reduced their swelling tendency. Pellet quality improved due to formation of sufficient .
A new fluxed pellet for use in ironmaking is obtained by mixing and indurating about 1 to about 20%, by weight of the pellet, of ground melt shop slag fines with similarly ground iron ore concentrate, so as to achieve particular ranges of silica content, CaO/SiO 2 ratio, and MgO content. The melt shop slag fines have been considered a waste material, but contain significant slag and metal values.
