Iron Ore Pellets Induration Solutions Metal 7

Iron ore green balls are soft and easy to break. So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users. Two indurating furnace technologies dominate the pelletizing industry, the

Degradation of Refractory Bricks Used as Thermal

Oct 26, 2009· Degradation of bricks in an iron ore pellet producing kiln has been investigated. Lab‐scale tests of brick/slag interaction performed under different temperatures, atmospheres, and alkali additions show that addition of alkali dissolves the mullite in the brick and leads to formation of the phase nepheline (Na 2 O·Al 2 O 3 ·2SiO 2).At a high temperature, the grain boundary where nepheline

Introduction to Iron ore Pellets and Pelletizing processes

Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter
