The influence factors of KR process, as well as desiliconization and dephosphorization pretreatment were studied by using 150 t ladle furnace. In this study, the reuse resources such as converter dust and iron oxide ball were used as the oxidant, and the desulfurizer was added into the ladle furnace at a certain ratio in the condition of KR hot metal pretreatment, the technological effect for simultaneous removal of silicon and phosphorus was sought factor. The result shows that remove part of silicon and phosphorus in molten iron is feasible, but the condition is harsh, the current production conditions can not be fully met.
