Synthetic slags - Weerulin

Synthetic slags. Due to its high sulphur-solubility a calcium-aluminate slag is also well-suited for ching slag in the steel ladle. Its low humidity content makes the slag a good choice in the ladle furnace and other situations, where the usual calcium-fluorspar slag does not provide the required low hydrogen content in the steel.

Formation of Low-Melting-Point Inclusions in Al-Deoxidized

2014/03/19· ZrO 2 crucible experiments were carried out in the laboratory to study the formation of low-melting-point inclusions in steel, during which aluminum deoxidization and a high-basicity calcium aluminate refining slag (CaO/SiO 2: 6 to 8, Al 2 O 3 40 to 45 pct) were used. 40 to 45 pct) were used.
