Qin Mingfu (No. 4 Steel Plant of Changcheng Special Steel Co. )
Influences of unit time on Ar volume blown into Steel liquid per unit weight and of slag thickness on deoxidation are discussed in the paper. The control of Vacuum Air-Pumping temperature and vacuum killing temperature is also ana lyzed. At last, how much aluminium will be fed when final deoxidation is carried out is studied.
