In order to set up a titanium alloy recycling route in Europe, UKAD, a joint-venture between Aubert & Duval and UKTMP, ADEME and Crédit Agricole Center France, created the company EcoTitanium. The recycling is performed thanks to the PAMCHR process with the aim of producing aeronautical titanium alloy ingots.
The research work is focused on the refining hearth stage, a very important step where low and high density inclusions have to be removed. A 3D numerical simulation of the thermal and hydrodynamic behavior of the liquid metal bath has been set up based on Ansys-Fluent CFD software. Thermal and shear effects of the plasma jet on the turbulent flow have been modelled together with the transient displacement of the torches. A comparison between the results obtained experimentally and numerically is carried out in order to validate the numerical model, both for a pilot furnace, and the industrial EcoTitanium furnace.
