Method for producing low hydrogen content in steels produced by
subsurface pneumatic refining
摘要:
The production of low hydrogen steel is achieved in subsurface pneumatic refining processes by proper melt practice ensuring adequate gas sparging during the overall refining sequences, minimal time delays in the latter stages of refining, and proper control of the vessel off-gas.
