Abstract During semisteel smelting process, less silicon,manganese are oxidized making.Slag formation difficult.A study was carried out to find suitable technology,which can reduce slag amount,give a new slag system of high metallurgical effect.Thus three slag forming.They set down three agents were tested.The results showed,that all three agents are satisfactory in terms of slag formation time,operation of blowing,consumption of slag forming agents dephosphorization.In this way, the metallurgical effect of slag can be increased by adding such agents to obtain slag with reasonable basicity,low FeO content.
