Sintering Characteristics Of Indian Chrome Ore Fines

Aug 11, 2009 However, the maximum sintering temperature as well as the sintering time can be decisive factors for chrome ore sintering. The bed height for the chrome ore sintering process should be kept low, owing to the possibility of excessive heat generation during sintering for the deep-bed sintering process, which may eventually damage the sinter machine.

Sintering Characteristics of Indian Chrome Ore Fines

Sintering Characteristics Of Indian Chrome Ore Fines

Sintering Characteristics of Indian Chrome Ore Fines. Chrome ore concentrate consists of high-temperature melting oxides such as Cr 2 O 3, MgO, and Al 2 O 3. The presence of these refractory constituents makes the ore a very high melting mineral. Hence, it is difficult to produce sinter from chrome ore by a pyrometallurgical route.
