AUSIRON - CAPABILITY  

Ausmelt has successfully commercialised its Top Submerged Lance process in a wide variety of non-ferrous applications, in each case successfully scaling up from pilot plant operations.

 

This experience, coupled with operating experience from both the AusIron Demonstration Plant and its wide range of commercial operations provides a solid platform for commercial application of the AusIron® Technology.

 

The AusIron® process has been developed with a focus on the inherent process flexibility necessary for commercial scale facilities to be rapidly optimised. The use of multiple lances, each generating an effective 'process zone', and distributed post-combustion allows scale up to be a combination of size and number of lances. Effective use of oxygen enrichment at both the lance tip and post-combustion shroud, controllable independently, allows fundamental process characteristics to be maintained on scale-up.

To suit the projected commercial applications for AusIron, standard furnace modules have been developed for nominally 300,000 and 500,000 tonne per year AusIron facilities. The table above illustrates some of the primary specifications of these modules.
