The AIR / Aluminium In-line Refiner is a conventional box that processes molten aluminium between the furnace and the casting pit.
The AIR results from the technology transfer of the A622™ developed by Alcoa in the 70’s and modernized since. Its unique design comprises separate processing chambers (one per rotor), an additional flotation chamber, a sealed roof, an airlock system at the box inlet and outlet, and specifically designed rotors. With such features, the AIR is used to reduce hydrogen, non‑metallic inclusions and alkalis in a simple and optimal in-line metal refining process.
Thanks to the various options and configurations available, the AIR is a flexible refiner that will exceed all your expectations not only in terms of metallurgical results but also of ease of operation and low maintenance requirements.
The AIR is particularly effective for continuous casting applications, or when few alloy changes are required, or for particular high‑end products.
