The Tangshan local magnetite and high calcium powder mixing and balling,thermodynamic simulation with X-ray diffraction analysis,high temperature thermal analysis instrument,while the use of Fact Sage,studying on laws of basicity and temperature effects on the strength of the pellets. The results showed that with the increase of basicity,the strength of the pellets was increased and then decreased trend changes,and when the basicity is 1,calcination temperature controlled at 1250 ℃ of pellet roasting ball strength reaches the maximum. Appropriate amount of liquid phase contributes to Fe3+ migration,hematite crystallized the strength of the pellets is larger; the excess phase blocking Fe3+ migration,hematite recrystallization is restricted,reduce the strength of the pellets.
