The effects of double calcium treatment mode (Ca treatment-RH-Ca treatment) and single calcium treatment mode (RH-Ca treatment) on removing inclusions are studied with the process route of BOF-LF-RH-CC. The study results showed that the size and number of inclusions in molten steel with single calcium treatment mode when RH left were smaller than those with double calcium treatment mode so that single calcium treatment mode was better than double calcium treatment mode.
