Abstract

Through the adjustment of desulfurizer in KR desulfurization process, the efficiency of desulfurization is increased obviously on condition of maintaining the same KR desulfurization process. While the desulfurization rate is as high as 84.2% and this is 3.2% higher than that before optimization. Consumption of desulfurizer is 12.3kg/t hot metal on average which is 1.4kg/t hot metal than that before optimization. In addition, TFe content in desulfurizing slag is 10.4%, which is reduce by 3.25% of the value before optimization. There is nearly the same content of carbon and vanadium in hot metal. The optimized desulfurizer can be used in KR desulfurization process, and wonderful results have been gotten. Therefore, it has a good prospect of application.
