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)×10-⁶
average oxygen content was 9×10-⁶ 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.
