Ultrasion is currently working on a new ultrasounds-based light alloys technology in order to launch a new, cleaner and more effective degassing technique. The current techniques, based on the purge of a gas mixture during melting, have proved to be expensive and harmful to bystanders’ health (due to concentrations of chlorine and fluoride), and have shown limited efficiency.
Advantages
- Complete elimination of harmful and environmentally unfriendly gases from the process
- Elimination of rotational, porous and fragile components that can contaminate the molten metal
- Optimized sequence that allows for short treatment time with maximum effect
- Applicability to either continuous or batch processes
- Applicability to a wide range of casting processes and liquid metals
- Removal of oxides in addition to dissolved gases
Applications
- Generation of slurry semi-solid for processing light alloys by other techniques such as casting, extrusion or forge
- Production of metal-matrix composites by ceramic particle dispersion
The ultrasonic Light Alloys technology has been developed in collaboration with Eurecat in the frame of the research projects CERORSOM, cofounded by CDTI through the Eurostars program of Eureka under grant agreement number CIIP-20172025, and Ultragassing and DOSHORMAT, cofounded by the Research Executive Agency under grant agreement number 286344 and 606090, respectively.
The technology is commercialized by HORMESA (Hornos y metales SA), partner of all these projects.
