The silicoferrites of calcium and aluminium (SFCA) developed in sinter A2 and A3 are acicular in structure which provides better strength to the sinter. Also the porosity is more in case of A2 and A3 which can accelerate the reducibility process.

Effect of Binders on the Crushing Strength of Ferro MDPI

Without iron ore, QM had the highest crushing strength, which was 92.25%. When the addition amounts of iron ore were 10% (QE1) and 20% (QE2), the ferro-coke could maintain a higher crushing strength, which were 78.94% and 72.11%, respectively. When the addition amount of iron ore was 30%, the crushing strength of QE3 dropped to 18.15%.

Solid-Fuel Combustion in the Sintering of Siderite Ore

2018-11-29  Two technologies are considered for the preparation of solid fuel used in sintering: crushing with portions of roasted siderite ore whose strength is less than that of the fuel; or crushing of the fuel alone and subsequent mixing with the ore portions. On the basis of derivatographic data, kinetic equations are written for the high-temperature combustion of coke fines in a fuel–ore mixture

Automated Optical Image Analysis of Iron Ore Sinter MDPI

Sinter quality is a key element for stable blast furnace operation. Sinter strength and reducibility depend considerably on the mineral composition and associated textural features. During sinter optical image analysis (OIA), it is important to distinguish different morphologies of the same mineral such as primary/secondary hematite, and types of silico-ferrite of calcium and aluminum (SFCA).
