【 摘 要 】

The use of titanium containing molten iron can expand the sources of raw materials, reduce the cost, but the process produce serious foaming slag, low dephosphorization proportion and the consumption of lime is high. The technicians have improved the operation process through experiments and solved the problem of efficient and smooth blowing of hot metal containing titanium. Through mine phase composition analysis of slag using SEM and EDS, the distribution of titanium and the regularity of phosphorus retention are found, and measures to prevent phosphorus recovery in the later stage of converter are put forward.
