网页2017年10月1日Through the 3D reconstruction of two types of iron ore sinters, the morphology and distribution of minerals in three-dimensional space were analyzed, and the volume fraction of minerals in a 3D image was calculated based on their pixel points. In addition, the microhardness of minerals was measured with a Vickers hardness tester.

网页2016年9月3日Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.

网页2022年3月24日High mechanical resistance to breakage is one of these key properties of sinters as under-sized sinters (<~5–6 mm) are categorised as return fines and sent back to the feeding hoppers for reprocessing. Hence, it is important to maintain desirable size of the sinter lumps (as opposed to being fractured into under-sized materials).
