The Φ210~310 mm round tube billet of gas bottle steels such as steel and steel 30CrMo and 37Mn are produced by 150 t EAF- 150 t LF(VD)- CC process at Tianjin Pipe Co.The production statistic data showed that during LF refining using ≥50Si
≥12Ca
≥13Ba alloy to replace total aluminium deoxidization
the [Al
t
]
decreased to 0.006% from 0.026%
the oxygen content in steel was 25×10
-6
with the result that the cleanliness of steel increased and the clack rejection rate decreased obviously.
