The secondary refining technology is an advanced technology which can improve product quality and reduce the production cost. Also it's an indispensable tache in modern steelmaking process. Metallurgy functions of the refining technology involve the accurate control of chemical composition and temperature, removing and form control of inclusion, reduce the content of S、Ca through deoxidation, eliminate H、O、C impurity, deairing in the vacuum atmosphere etc. Only through strengthening each function, the advantage of the refining technology can exhibit, then producing the high quality and pure steel!
