Linde is the market leader of innovative gas solutions for the aluminium industry. Our industry leading portfolio ranges from gases and equipment to process consulting and services.
The focus is on the use of oxygen to enhance the combustion process, increase efficiency and reduce emissions. Our oxyfuel solutions include a wide range of technologies. Our expertise in heat treatment enables aluminium industry to achieve the desired microstructure, physical properties and surface properties required.
We also employ a wide range of inert gases to optimise results and cut production cost. Gas purging improves the quality of the final product by degassing, removing inclusions and homogenising. Other practical examples of how we put inert gas to good use include annealing, dross cooling and extrusion. We use a protective nitrogen atmosphere to anneal aluminium coils, thus reducing oxidation and discolouration. For dross cooling an inert atmosphere enhances the metal yield by preventing oxidation. Liquid nitrogen also improves quality and productivity in extrusion cooling.
