Thermodynamic Constraints and Prospects for Intensified Steel Deoxidation

open access: yessteel research international, EarlyView.
The article provides a short survey of steel deoxidation and considers how to increase its efficacy. Bringing a specially tailored, powdered slag into the reaction site can directly bind the deoxidation product oxides, resulting in lower dissolved oxygen activity, total oxygen content, and cleaner steel.
