1. Up to 52% sulphur removal, with partition ratios around 50 was achieved for silicon killed steel. This result far exceeds reported best practice results. Total slag generated for the treatment was approximately 15 -20 kg of slag per tonne of steel. The ladle freeboard space required to hold this volume of slag was not an issue for SSM operations, 2. This practice allows treatment of high sulphur heats in the LMF efficiently and cost effectively. 3. Silicon killed steel produced in an EAF using commercial scrap, with a meltout of 0.025% S, can be desulphurised in an LMF to achieve thin strip casting quality requirements. 4. No adverse effect on ladle refractories or product quality was evident. 5. The practice can be easily adopted by any EAF Steelmaking operation if desulphurisation becomes an issue when producing sulphur critical Si/Mn killed steels (eg. Spring Steel). 6. SiC is a more efficient slag deoxidising agent than CaC_2 at low slag FeO levels. 7. Alloy recoveries were improved and also CaSi wire consumption was reduced.
