Description
A leading company in Middle East (C.M.E.) commissioned an automatic sealing slag door (SwingDoor™) system without door burner supplied by INTECO PTI on an Electric Arc Furnace (EAF), operating with approximately 80 % cold Direct Reduced Iron (DRI). This installation represents one of the first industrial applications of automated sealed slag door technology in a DRI-dominant furnace, whereas prior global references were primarily scrap-based.
The project aimed to enable closed-door melting practice, improve slag retention and reduce air ingress. Initial commissioning identified several operational and design constraints which were resolved by subsequent engineering modifications. Following operational stabilization, validation during the Performance Guarantee Test (PGT) confirmed measurable improvements, which were determined to be even better than previously calculated, in:
• Electrical energy reduction
• Electrode consumption reduction
• Metallic yield increase
• Flux consumption reduction
• Slag generation reduction
This paper documents installation constraints, commissioning learnings, operational performance, and future enhancement opportunities including slag level prediction and automated de-slagging optimization.
