Abstract：To meet the requirement of low phosphorus and titanium, the double slag and slag-remaining technology was adopted in the smelting process. The slagging alkalinity and FeO are controlled within a range of 1.5~2.0 and 15%~20%respectively for the first slag formation to ensure the good liquidity of slag. The adding of quartz sand can promote slag melting process and improve the liquidity of slag and dephosphorizing capacity for the second slag formation. The slag solidified operating is adopted for slag-remaining furnaces. The confirmation system must be carried out to avoid of splash during pouring melted iron. Smelting process is smoothly, the C is 0.12%, P is 0.003 9% and Ti is 4.5 × 10-6 at the end-point,the dephosphorization and titanium removal rate achieved above 95%and 98%respectively.
