| Abstract: | The 100 t RH vacuum refining unit is equipped with RH-WPB water-cooling top lance powder injection system, the set of powder inject system has one-time largest injection volume 2 000 kg with theory max injection rate 250 kg/min and using injecting powder desulfurizer 80CaO/20CaF2. The RH-WPB treated results on steel 14Mn5V, steel 30CrMnSi and steel 27CrMo27VS show that after RH powder injection treatment the sulphur content in liquid decreases respectively from 42 x 10-6, 28 x 10-6 and 39 x 10-6 to 28x 10-6, 15 x 10-6 and 22 x 10-6 , it has obviously desulphurization effect. |
