| Abstract: | The P content in molten steel during eccentric bottom tapping of Consteel electric are furnace was ≤0.010% by controlling temperature of molten steel 1560~1590 ℃ and melting with foaming slag in whole period. The oxygen content in bearing steel produced at Guiyang Stecl was(5～11)×10-?,average oxygen content was 9×10-? by low basicity compound slag refining in ladle furnace,≤67 Pa VD treatment with Ar stiring for 20 min, Shield cast in whole period and mold electromagnetic stiring for 150 mm×150 mm billet casting. |
