In order to study the effect of MgO content on high magnesium alkaline pellet strength,Factsage thermodynamic software,liquid nitrogen adsorption instrument,and X-ray diffraction method had been used with fixed basicity of 1. 0.The results show that under the premise of 1. 0 fixed basicity,with the increase of MgO content,the amount of liquid phase in high magnesium pellet decreases,and Miaogou Iron Concentrate Ore,high magnesium powder and high calcium powder pore size distribution all are in range of 1~50 nm,which belongs to the mesoporous and relatively high magnesium powder and high calcium powder,and Miaogou iron concentrate ore area is smaller.The mechanical strength of pellet firstly increases and then decreases; roasting ball strength increases firstly and then decreases.At the given basicity of 1. 0,when the MgO content of 1.0% the strength reaches the maximum value.
