Dynamic model of the ladle treatment of steel

Resumo

The basic factors that affect the ladle treatment of steel are analyzed. Balance equations, chemicalkinetic equations, thermodynamic equations, and hydrodynamic and gas-dynamic equations are written for the treatment of steel in a ladle–furnace unit with a vacuum-degassing system. A cylindrically symmetric calculation grid is developed. The equations are adapted on the basis of the finite-element method.
