MgO-containing flux may have a series of effects on the quality of sinter and performances of the blast ***,the fundamental mechanism of the effects of MgO on the sinter strength was *** the chemical reagent and industrial flux were used for preparing the *** experimental results show that the sinter strength decreases with MgO *** are three reasons for *** first reason is diffusion *** all of the CaO may react with Fe2O3 and generate CaO Fe2O3,but most of MgO cannot react with Fe2O3,and it still remains in the state of original *** diffusion rate of MgO in iron oxide is only 17.51μm/min in 30 *** second reason is the fluidity and ability to generate liquid *** the case of Fe2O3 mixed with CaO,there is some liquid phase formed above 1200℃,while in the case of Fe2O3 mixed with MgO,even at 1200 and 1220℃,there is still no liquid *** third reason is *** the case of industrial flux,the compression strength of the specimens made of Fe2O3 and limestone is 0.52 and 0.71 kN at 1150 and 1180℃,respectively,while that of the specimens made of Fe2O3 and magnesite is 0.48 and 0.56 kN,***,the fundamental mechanism of the effects of MgO additive on sinter strength can be better understood based on the diffusion rate of MgO in iron oxides,the fluidity of liquid phase,and the self-strength of bonding phase.
