Abstract

This paper aims to assess the efficiency of graphite impellers type A and B, investigated in the study of an aluminum refinement process using a physical model of the foundry degassing unit. This model operates in the laboratories of the Environmental Research Department of the Institute of Technology and Business in České Budějovice. For this purpose, a series of experiments were performed for each impeller type with different process parameters. The efficiency was evaluated based on oxygen concentration in water reached after 180 s of the refining process. Impeller A was found to achieve lower oxygen concentrations in water after 180 s and was therefore considered to be more efficient. The conclusions will be further verified under operating conditions of the Die-casting Division of MOTOR JIKOV Slévárna (Foundry) a.s.
