摘要：
The effects of powder composition and concentration on H//2 content in steel and the time of flaking suppression treatment of castings, nonmetallic inclusion levels and composition and mechanical properties of 14KhGSN2MA steel having a high flaking tendency were investigated. Using a combination of metal quality characteristics it was estimated that the best results can be obtained using joint ladle refining of steel by powdered NaCl (added at 0. 5% of the metallic charge) and Ar.
