摘　　要：通过对铁水预处理、转炉底吹、氧枪枪位及氧气流量、转炉吹炼终点及出钢下渣、脱氧合金化等转炉工序各个生产控制点的精准管控,有效避免了SPHC钢种的终点氧化性强、夹杂物高、钢水硅含量高、出钢下渣回磷回硅等技术瓶颈问题,降低了脱氧铝耗成本和生产成本,保证了SPHC钢种的钢水可浇性,提高了钢水质量。The technical bottlenecks including strong endpoint oxidation,high inclusions,high silicon content in molten steel,recovery of phosphorus and silicon from tapping slag of SPHC steel can be effectively avoided by the accurate control of various production control points in convert processes such as hot metal desulfurization,converter bottom blowing,oxygen gun position and oxygen flow,converter blowing endpoint,tapping slag and deoxidation alloying,which are attributed to decrease the cost of aluminum consumption and production for deoxidation,guarantee the molten steel castability of SPHC steel,and improve the molten steel quality.
