Factors Influencing the Bonding Phase Structure of Iron Ore Sinters

C. E. Loo, W. Leung
2003 ISIJ International  
The tumble strength of sinter particles and yield from a sinter strand are largely determined by the inherent strength and structure of the bonding phases present.  ...  The study showed that phosphorus, silica, alumina and magnesia levels, sinter basicity and maximum sintering temperature influenced bonding phase structure through the reshaping and coalescing of the melt  ...  This should have an impact on the behaviour of the melt and properties of pores in the analogue sinters.  ...
