Resumo
EOF is a 100% national reactor equipped with a scrap preheater and 4 oxygen injection points. This article investigates two parameters of these oxygen injectors through a physical model on a 1/6 scale of the industrial reactor. It also brings the novelty of measuring the mixing time using two techniques simultaneously: conductivity meter and lux meter. The results show that higher flow rates and shorter bath launch distances lead to shorter mixing times. It also presents a distinction between the readings by the two techniques depending on the reading method versus test conditions. Finally, it allows evaluating the best configuration that minimizes the passage of material through the slag port.

THE RESULTS SHOW THAT HIGHER FLOW RATES AND SHORTER BATH LAUNCH DISTANCES LEAD TO SHORTER MIXING TIMES.

FINALLY, IT ALLOWS EVALUATING THE BEST CONFIGURATION THAT MINIMIZES THE PASSAGE OF MATERIAL THROUGH THE SLAG PORT.
