Abstract

This work presents a thermodynamic and experimental analysis of the phases that precipitate in the non metallic inclusions depending on the contents of aluminium (Al), titanium (Ti) and oxygen (O) in the steel, and their influence on the nozzle clogging. For the thermodynamic analysis, the program FACT WIN (Facility For The Analysis of Chemical Thermodynamics) subroutine Equilib. was used. The experimental tests were carried out in an TAMMANN furnace, in an argon atmosphere. The control of the content of dissolved oxygen was carried out by means of sensors of solid electrolyte bases zirconia. The characterization of the inclusions was carried out with SEM, EDS and by means of the technique of fractional reduction with carbon. A good agreement was observed between the thermodynamic predictions and the experimental results.
