Abstract

A numerical method was used to study influence of the charge mass change on the process of converter slag reduction. A numerical simulation was performed with three different quantities of reduced slag. The relation between changes of Cu₂O concentration and duration of the reduction process as well as between the rate of Cu₂O reduction in the slag and Cu₂O concentration were analysed. It was found out that the duration of the process is proportional to the amount of the treated charge. The rate of Cu₂O reduction from converter slag decreases with the process duration and increases with increasing concentration of Cu₂O in the slag.
