FRI-320 The FRI-320 is a movable, rotary injector system designed to treat molten aluminum in furnaces. The FRI-320 can be equipped to perform bi-gas metal treatment or solid refining agent injection. The spinning rotor head can be moved or tilted allowing for angled operation in tight fit conditions. This mobile system can be easily relocated from one furnace to another furnace. The submerged propeller design promotes uniform mixing and circulation of the melt. Spinning rotor degassing efficiently removes unwanted hydrogen from the melt. The FRI-320 with solid refining agent injection allows a steady flow of refining agent below the metal line which enhances alkali metal and inclusion removal. The combined effect helps improve the quality of aluminum alloys and reduces operating costs. Advantages Efficient alternative to manual wand fluxing and porous plugs Improved hydrogen, inclusion and alkali removal Submerged propeller maximizes mixing of molten metal Uniform temperature throughout bath Uses gas or solid refining agents more efficiently Less dross formation Reduced annual operating costs Applications Melting furnaces Holding furnaces Metal treatment with gas or solid refining agent injection
