Abstract

Abstract

In view of the physical and chemical properties of high-grade vanadium titanium magnetite, single firing contrast experiment, different substitute ratio experiment of high-grade ore and orthogonal experimental study on parameter optimization of sintering technical and economic indexes of sintering fuel ratio, mixture moisture and material layer thickness under the condition of highest substitute ratio were carried out. The experimental study shows that the high-grade ore has the characteristics of high iron, low silicon and titanium, finer particle size and is very sensitive to the moisture control of the mixture. With the increase of the ratio of high-grade ore in sintering, the comprehensive score of sintering index shows a decreasing trend. The influence on the technical and economic indexes of this sinter is water, fuel ratio and material layer thickness in descending order. The optimal sintering conditions of this sinter obtained in the laboratory are as follows: mixture water 6.5%, fuel ratio 4.2% and material layer thickness 670 mm. Industrial test results show that the sintered with addition of 20% of the mineral, the sinter high sinter TFe grade is increased by 0.8%, 0.6% lower content of TiO₂, drum index is basically remain unchanged, the concentration of SiO₂ sintering flue gas imports in low 22%.
