Abstract: Aluminium dross, which is a waste product of aluminium manufacturing process, is toxic and hazardous in nature. Therefore, search for a suitable disposal method becomes crucial to process this dross effectively. Recycling is recognised as the best way out for sustainable development. Present study discussed the utilisation of white aluminium dross-based briquetted synthetic slag (WADBBSS) in place of pre-melted synthetic slag (PMSS) during secondary steelmaking. X-ray diffraction (XRD) analysis of WADBBSS shows around 9% of metallic aluminium. Viscosity analysis of WADBBSS and PMSS shows a difference of 0.04 Pa.s at steelmaking temperature. Industrial trials carried out with the addition of WADBBSS shows a reduction of 0.07-0.08 kg of aluminium consumption per tonne of liquid steel compared to heats processed with PMSS. There was no adverse effect observed in desulphurisation rate and nitrogen pick-up. Trial results established that WADBBSS can replace PMSS in terms of effectiveness.
