Abstract To the problem of low intensity and poor property of anti-pulverization in low-temperature reduction process occurred in low silicon sinter, the microstructure of sinter offered by one iron and steel corporation was investigated. The result shows that the content of magnetite and calcium ferrite is low , while that of vitreous silicate with poor intensity and hematite with good reducibility are high. In order to improve the property of anti-pulverization in low-temperature reduction process, the effect of sintering process(fuel matching , the thickness of stuff seam) and the content of sinter(Al2O3/SiO2, basicity and MgO content)were studied. The result shows that the optimum fuel matching and the thickness of stuff seam for the present sinter are 5.0% and 515mm, and the Al2O3/SiO2, basicity and MgO content are 0.31、2.3、2.02%, respectively.
