Abstract
With the increasing shortage of iron concentrate powder resources, the optimization of blast furnace charge structure by using the fluxed pellets has become an important method to reduce the cost of iron making in iron and steel enterprises. To solve some problems, such as bonding, ringing, and so on; the effect of MgO on the properties of pellets has been studied. The results show that with the increase of MgO , the compressive strength of green pellets increased, while the dropping strength of green pellets decreased. The decrepitation temperature increased at first and then decreased, and the bond rate decreased. The performance of the pellets improved. The hematite content decreased and the magnesium ferrite content increased in main crystal phase of the pellets, which was mainly linked by crystal bond.
