Experimental study on sintering of FMG blend fines instead of yandi fines
LI Guodong
Abstract：To reduce the cost of sintering ore blending,Taiyuan Iron & Steel(Group)Co.,Ltd(TISCO)adopted FMG blend fines to replace the previously used Yandi Fines.The article analyzed the chemical composition,particle size composition,particle morphology and other physicochemical properties of FMG blend fines and Yangdi(YD)fines,and through the sinter pot test and industrial test,the metallurgical properties and mineral phase quality of sinter ore were analyzed when using FMG blend fines instead of YD fines.The experimental results show that using 15％FMG blend fines instead of Yangdi fines,the permeability of the sintered material layer slightly decreased,and the physical performance indicators of the sintered ore showed a downward trend.Nevertheless,the SiO2 content of the sintered ore declines and the iron content rises.On the whole,its output and quality indicators can satisfy the production requirements of super-large blast furnace.
