The search for more efficient methods for degassing aluminum alloy melts has always been
of great interest for the metal industry because the presence of hydrogen and oxides in the …

The degassing of aluminium alloy melts is a crucial step in the production of high-quality
casting products, as the presence of dissolved hydrogen and oxide bi-films is detrimental to …

Physical modelling is successfully used to understand mechanisms involved in the
aluminium refining process by injecting inert gas into the liquid metal through rotors. Two …

The refining process is one of the essential stages of aluminum production. Its main aim is to
remove hydrogen, that causes porosity and weakens the mechanical and physical …

The hydrodynamic performance of a stirred ladle, for an aluminum degassing system in
turbulent regime, is analyzed experimentally. This study explores the dynamic flow features …

Obtaining high-quality aluminum is associated with the use of an effective method of
refining, which is argon-purging, in which gas bubbles are introduced into the liquid metal by …

A physical model of a batch aluminum degassing reactor equipped with the rotor-injector
technique was used to measure deoxidation kinetics of water, assuming that this kinetics is …

Concern for the environment and rational management of resources requires the
development of recoverable methods of obtaining metallic materials. This also applies to the …

In this study, the optimal conditions of gas bubbling filtration (GBF) treatment for securing
highly-clean molten Al-Si-Mg-Cu alloy were identified. The effects of GBF treatment time and …

Both the wear and the geometry of the rotor determine the efficiency of the process of
aluminum refining. The paper presents wear tests of two different rotors: I (pump type) and II …
