The invention relates to the field of
metallurgy, in particular to a single
pipe style multifunctional vacuum refining
system and a method thereof. Aiming at the problems that when DH, VD, RH and single snorkel refining furnaces are used for
steelmaking, the refining efficiency is low and a whole furnace steel scrapping risk exists in a
smelting process, the invention provides the single
pipe style multifunctional vacuum refining
system and the method thereof based on metallurgical
kinetics theoretical calculation. An
argon blowing device is arranged around a single dip
pipe, and
argon blowing bubble size and amount and
argon blowing time are adjusted and controlled, so the refining efficiency is improved, the service life of the dip pipe is prolonged, and the potential scrapping risk of
ladle water caused by the fault or low efficiency of the argon blowing device when argon is blown at the bottom or only at one side is eliminated.
