The 150 mm x 150 mm casting billet of bearing steel GCr15 is produced at Jiyuan Iron and Steel Co by using 601 top and bottom combined blowing converter melting with carbon catch operation to control converter end [C
]
0.08% ~0.20%
ladle bottom argon blowing and adding aluminium-iron in ladle during tapping for oxidation
whole process argon shielding casting and casting billet stacking slow cooling process. Practice results show that the oxygen content in bearing steel GCr15 is (6.3 x 11.9) x 10
-6
average oxygen content is 9 x 10
-6
and the macro structure of casting billet is better.
