CatId=6. swf. com Keywords: cast house technology, greenhouse gas emissions, life cycle assessment Abstract The aluminium industry is reducing its carbon dioxide emissions and environmental footprint. In order to identify and prioritise areas in the cast house where greenhouse gas emissions can be reduced it is necessary to quantify CO2e (CO2 equivalent tonnes) emissions for the various cast house operations. In this study two typical cast house layouts are examined. 85% aluminium remelt ingots are produced using chain conveyor ingot casting machines.

Prasad (a) 39 (b) Figure 2. (a) General arrangement of the skimming rig (with optional lid shown) constructed at University of Queensland; (b) Oxide skim being collected by the pulling the skimming blade across the melt surface at regular time intervals. These skims were weighed and then analysed for metal content using a specially-formulated molten salt mix to separate the oxide from the aluminium. The molten mixture was then chill solidified, the crystallised salt dissolved away in warm water and the metallic droplet(s) residue was dried and weighed.

Timing is everything, skimming too late can cause dross to build up, reducing melting efficiency and causing overheating of the molten surface which ultimately generates more dross. Traditionally, forklift trucks equipped with homemade tools are used in the aluminum industry to carry out routine furnace operations such as skimming and cleaning. While functional, the results are inconsistent and reliant on the judgment and skill of the operator. Improper skimming technique can pull a significant amount of aluminum out of the furnace.
