Experimental study on crushing strength and Young’s ...
2020-12-1 For both the crushing strength and Young’s modulus of iron ore granules, their desired value should be the higher-the-better type. The S/N ratio is calculated as (4) S N = − 10 log ( 1 m ∑ i = 1 m 1 Y i 2 ) , where m is the total number of tests and Y i is the experimental results of the i th test.

A forecast model of the sinter tumble strength in iron
Iron ore sinter is an ordinarily utilized iron-bearing burden in BF iron-making unit. The sintering agglomeration procedure aims to form high strength sinter including granulating of the mixed materials, distributing the granulated materials and then igniting the fuels (coke or coal), sintering the iron-bearing materials by the combustion of fuel in a grate with air-suction beneath the grate ...

Effect of Binders on the Crushing Strength of Ferro-Coke
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%.

Automated Optical Image Analysis of Iron Ore Sinter -
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).
