Abstract:
Currently, 23.9% of Brazil's steel production uses electric arc furnaces (EAF), with the remaining 76.1% produced via the integrated route. To improve EAF performance and safety, automatic slag doors are essential. This paper introduces two SMS technological innovations designed for energy savings, reduced CO2 and NOx emissions, increased productivity, and enhanced safety. The first, Condoor, with over 20 global installations, showcases design improvements, reliability, and extended lifespan, validated by plant feedback. The second, TS Pro robotic sampling system, complements Condoor by eliminating the need for operators near the furnace, enhancing safety. SMS group's 150 years of experience drives continuous innovation in the metals industry. This paper highlights the benefits of these technologies, including improved power consumption, electrode usage, raw material efficiency, and process time. Condoor, combined with SCAD, optimizes parameters like carbon injection and flux consumption, stabilizing cycle times and enhancing slag control, essential for using alternative iron sources in EAF.
