*The final verification of the complex refining technology for the production of demanding aluminum castings of the ROCKER COVER type was carried out. In the period 01/2019-12/2022, aluminum alloy refining experiments were carried out on a rotor degassing unit focusing on the most suitable type of graphite rotor, the application of breakwaters, the use of melting salts and the recommendation of optimal operating conditions based on the results of physical and numerical modeling together with the verification of results from operating conditions. All melts from the verification series met the quality parameters defined by the customers for whom the project outputs are planned to be applied.
