Calcium Treatment An Overview Sciencedirect Topics

The affinity of calcium to sulfur is strong enough to prevent reaction of Ca with Al 2 O 3 to such an extent that formation of liquid aluminates could happen without remarkable CaS formation which, necessarily, leads to desulphurization. However, medium sulfur levels from 0.020S to 0.050S are attractive as resulfurized steels too and they are ...
