Abstract
A physical model based on similarity principles has been constructed for simulating the RH
degasser of Companhia Sideru´rgica de Tubara˜o (CST), Vito´ ria, ES, Brazil. The influence of gas
injection through nozzles in the upleg with simultaneous bottom injection of gas, as well as the
influence of nozzle blockage, on the circulation rate has been investigated. In addition,
mathematical relationships for mixing characteristics in the process have been evaluated.
