Evaluation of Implementation Trefimet High-Tech Thermal Lances on Tapping Process at BHP Olympic Dam Operation

This chapter delves into the evaluation of high-tech thermal lances, specifically the Trefimet TR-38 model, for the tapping process in the Electric Slag Cleaning Furnace at BHP Olympic Dam. The study compares the performance, speed, and wear on taphole components of the TR-38 with traditional burning bars. Laboratory tests and field trials at Olympic Dam revealed significant improvements in performance, with the TR-38 achieving a 128% higher speed and reducing the meters of product used per opening by 61%. Additionally, the TR-38 showed a 30% increase in the minimum remaining refractory thickness, indicating potential longevity benefits for taphole components. The chapter also discusses the method used for requirement analysis and the correlation between laboratory and field test results. The findings suggest that implementing the TR-38 thermal lance could enhance operational efficiency, safety, and cost savings in the tapping process. Future work includes long-term tests to further validate these results and assess the impact on safety and incident reduction.
