In normal sintering of iron ore, there is a wide difference in temperature the sinter bed between top and bottom; i.e. flame front gradually increases towards bottom because lower part gets longer time for drying preheating by exit gas. Therefore, may have insufficient fusion excessively fused. Thus, quality become inhomogeneous coke breeze requirement becomes higher than actual thermal require...

Secondary hematite (SH) is a serious factor resulting in reduction degradation of iron ore sinter blast furnace; however, until now, quantitative study for SH formation had not been reported. In this work, the effects gangue composition, including MgO, Al2O3 and SiO2, on solid-state sintering process fines were investigated quantitatively. It shows that decreased from 67.84% to 46.11%, 35.44% 2...

Sinter ore quality directly affects the stability of blast furnace production. In terms both physical and chemical properties, main indicators sinter are TFe content, alkalinity, drum index. By analyzing massive historical data on production a steel company, this study proposes prediction system based Granger causality analysis stacking integration algorithm. First, real sintering in enterprise...

May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of sintered layer during sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in ore sintering. In this study, strengthening granulation using pre-pelletizing expand utilization ratio was proposed. The experiments conventional granulation, si...

Silico-ferrite of calcium and aluminum (SFCA) is the primary bonding phase iron ore sinter, world’s most popular artificial feed material for ironmaking. However, fundamental questions about its crystal structure atomic occupancy at each site remain unanswered. To date, quantitative analysis (QPA) SFCA has mostly been conducted using two-dimensional information only provided regarding fractions...
