Description
Calcium (Ca) treatment is widely used in ladle metallurgy to modify alumina-based inclusions and improve steel cleanliness. The effectiveness of this process largely depends on the type of Ca-cored wires employed and the refining conditions, which influences dissolution behavior, calcium recovery and ultimately inclusion modification. This study examines two commonly used wire types-pure Ca and CaSi under various refining scenarios in the ladle metallurgy process. Their dissolution behavior and interactions with steel and slag are compared using thermodynamic tools, while their impact on inclusion modification is evaluated based on plant trial data.
