Question

How to avoid excess deoxidation in induction melt of steel?

Answer 1

hi there
it is usually necessary for the cross-interaction parameters ɛMO, ρMO, ρOM, ρMM,O and ρOO,M to be very negative in order to account for the very strong attractive interactions between dissolved M and Oatoms. Furthermore, in order to reproduce the measured data over a range of temperature, the interaction parameters must generally have a strong empirical temperature dependence, usually expressed as ɛ = a + b/T (and ρ = c + d/T). By using many empirical parameters, the interaction parameter formula reproduces the measured deoxidation equilibria over a limited range of temperature and composition
