Modeling the Dissolution of a Calcium-Containing Cored Wire during Ladle Treatment of Steel

A comprehensive model is developed for the assimilation of calcium from a cored wire; it takes into account heat transfer, sheath melting, the release and possible evaporation of calcium, and its subsequent reaction with nonmetallic inclusions in steel. The developed mathematical model is used to perform numerical calculations of the injection of a cored wire into steel for various operating regimes.
