Abstract

In order to meet the increasing demand for ultra low carbon and low nitrogen steel, the capacity of vacuum degassing processes as represented by RH processes must be improved. In this investigation, the behaviours of decarburization and nitrogen removal in RH processes were examined. For the effective decarburization high rate circulation, the desirable conditions found include high capacity of gas exhausting and strong perturbation in the vacuum vessel. The measures of preventing the nitrogen pickup was found to be very important for the refining of ultralow-nitrogen steel.
