In the present work laboratory sintering experiments have been carried out with iron ore fines of different alumina level (2.00 to 5.46 mass‐%) to know the influence of alumina on mineralogy, productivity, physical and metallurgical properties of sinter prepared …
The alumina shaped pellets should retain their properties and porosity even after exposure to humidity for an extended time. To this end, the samples used in the vapour adsorption experiments from the previous section were left exposed to air at ambient conditions for 12 months on a laboratory countertop.

Alumina inclusions are dendritic when formed in a high oxygen environment and often coalesce to create irregular shaped ‘alumina clusters’ as a result of the collision of smaller particles. These clusters significantly affect the mechanical properties of steel, especially fracture sensitive properties such as toughness and fatigue life, and may also result in the generation of surface defect.

Variables Affecting Pellet Properties: Pellet making is a complex process, requiring careful attention to the successive stages of feed preparation, balling, drying, firing, and cooling. Thus although the properties of the finished pellets are developed during the thermal induration or firing stage, the firing time and temperature are not the only variables which affect pellet properties. Ore ...

Correlation between the mechanical properties of iron ore sinter and the chemical composition of the calcium aluminosilicoferrite Ca 2 (Ca,Fe,Mg) 6 (Fe,Si,Al) 6 O 20 (SFCA) sinter bonding phase was examined. Sintering experiments with iron-rich, high-alumina and high …
The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.

08-05-2011· The effect of pellet basicity and MgO content on the melt formation and microstructure during the induration of iron ore pellets was examined. Fired pellets with varying basicity (0 to 0.8) and MgO (0 and 1.5%) content were tested for cold strength, reduction degradation index, reducibility, swelling and softening–melting characteristics.
The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.
