RFI | STAR Degassing and Fluxing Systems Rotary Flux Injector
To ensure aluminum meets stringent quality standards, the removal of dissolved alkali elements (such as sodium and calcium), non-metallic inclusions, and dissolved hydrogen is essential during molten metal processing. Traditional furnace fluxing techniques—whether by manually distributing solid flux over the melt surface or employing chlorine-based flux lances—remain widely used but come with operational and environmental drawbacks.
A modern alternative is the RFI (Rotary Flux Injector), which significantly enhances fluxing efficiency by injecting specially formulated salt mixtures directly into the molten aluminum. At the heart of the RFI system is a uniquely designed rotor. This rotor injects a carrier gas, typically nitrogen, which delivers finely divided solid fluxing agents beneath the metal surface. The intense mechanical shearing and gas dispersion generated by the rotor rapidly liquefy and distribute the flux throughout the melt, ensuring thorough and efficient impurity removal.
Recognizing that foundry layouts, furnace configurations, and production scales vary widely, the RFI system has been developed in multiple adaptable models. Each is engineered to accommodate diverse spatial constraints and operational requirements, offering a flexible solution for any plant configuration without compromising performance.
Key Performance Advantages
Enhanced Metallurgical Purity
- Achieves superior alkali removal efficiency, effectively eliminating trace elements such as sodium and calcium
- Significantly improves melt cleanliness through active inclusion reduction and flotation
- In the RGI and RFGI variants, a post-fluxing argon purging phase further reduces dissolved hydrogen content
Optimized Process Efficiency
- Delivers intensive, uniform melt agitation for rapid thermal and compositional homogenization during alloying
- Minimizes oxide dross formation, thereby improving metal yield
- Increases overall furnace throughput and operational uptime
Environmentally Responsible Operation
- Completely eliminates the need for chlorine in the RFI configuration
- Drastically reduces fugitive emissions and improves in-plant air quality
- Provides a safer, healthier working environment for operators
Configurable System Solutions
- The RGI (Rotary Gas Injector) utilizes the same advanced rotor-based delivery system but operates with chlorine-based refining, achieving significant chlorine reduction compared to conventional lance methods
- The versatile RFGI (Rotary Flux and Gas Injector) offers operational flexibility, allowing operators to seamlessly switch between flux-based and gas-based refining processes according to real-time production needs
