Abstract

THIS STUDY INVESTIGATES THE IMPROVEMENT OF ARGON PLUG PERFORMANCE IN AN ELECTRIC ARC FURNACE (EAF) STEELSHOP. THE EVALUATION COMPARES THREE PURGING PLUG DESIGNS: A STANDARD SLOTTED PLUG (PQ16424), A PLUG DESIGNED FOR BETTER THERMAL SHOCK RESISTANCE (PQ21507 WITH CASTABLE 3926), AND A NEW DESIGN WITH A REINFORCED MATRIX FOR SLAG RESISTANCE (TS3926). LABORATORY TESTS SHOWED THAT TS3926 OFFERED SUPERIOR THERMAL SHOCK RESISTANCE AND A LOWER TEMPERATURE DELTA. FIELD TRIALS WITH PQ21507 DEMONSTRATED A 35% REDUCTION IN EROSION RATE COMPARED TO THE STANDARD PLUG. ADDITIONALLY, THE PLUGS EXHIBITED MINIMAL CRACKING AND EXTENDED SERVICE LIFE, ALLOWING OPERATORS TO SAFELY UTILIZE THEM UNTIL A LOWER OPERATIONAL LIMIT. THESE FINDINGS HIGHLIGHT THE EFFECTIVENESS OF MATERIAL SELECTION AND DESIGN OPTIMIZATION IN ENHANCING ARGON PLUG PERFORMANCE AND PROMOTING SAFETY IN EAF STEELMAKING
