Dust Collection and Degassing

This category covers two process stages: pulse-jet baghouses collect fumes and particulates from melting and dross operations, while box- or launder-type online degassing units treat molten aluminum before casting to reduce hydrogen and carry out some non-metallic inclusions.

Selection points

• First determine whether the duty is fume collection or molten-aluminum degassing
• For dust collection: sources, air volume, concentration, gas temperature, humidity and emission target
• For degassing: metal flow, alloy grade, hydrogen target and inclusion-control target
• Duct and stack layout, or launder space, inert-gas supply and filtration conditions
• Power, control integration and safety requirements
