Sinter feed is an iron concentrate containing fine particles and moisture and, being similar to iron ore fines,quot1 is at risk of liquefaction, resulting in cargo shift and loss of stability. liquefaction is believed to have resulted in a number of casualties, causing the loss of many seafarers lives.
The formation of liquid phases, which agglomerate the iron ore, in pellets is achieved by an external source of energy fuel, natural gas or pulverized coal, as opposed to sintering, where liquid phases are consequence of the combustion of coke breeze 2.
Abstractiron ore pellets are made from rened and ground ore that is balled into spheroids and then heat treated. pellet properties are measured through standardized physical, chemical and metallurgical tests to guarantee a high quality end product. however to better understand the oxidation and sintering of iron ore pellets one has
Pellet bed heights up to 550 mm can be realized. the csp sinter car for sintering is used to air-sweep ore fines and sintering concentrates through the charge layer during sintering belt movement. the car consists of a split or one-piece cast steel body, steel sealing plates, and lattice grate.
