U.S.Steel Edgar Thomson BOP Shop conducted trials to reduce the usage of burnt lime and dolomitic lime. Two flux reduction methods were tested during the trial. One method used pure MgO to partially replace dolomitic lime and burnt lime and the other method varied the aim MgO level in slag acording to the silicon level in hot metal and final steel temperature. The results obtained from the trials are discussed in the paper. The flux consumption before and after the trials is also given in the paper.
