Summary

Mould systems working with air are the dominant technology for casting aluminium billets. To achieve high billet quality, it is important to have a reliable air feed to the mould and a uniform distribution of the melt temperature within a multiple casting unit. The AIRSOL VEIL® Technology Package, consisting of moulds, designed with the aid of pressure-loss calculations and a computerised air-feeding system, guarantees uniform air distribution over the mould circumference as well as optimum feeding of the necessary air-flow rate during casting. Also incorporated in the mould system unit is an optimised metal distribution system (launder) and an advanced design of starter blocks. The launder system, optimised by means of computer modelling, reduces the temperature variation across the casting unit to less than 10° Celsius. The Technology Package is rounded off by a starter block design which avoids the formation of starting cracks in the billets. This and the uniform melt temperature distribution lead to a significant reduction in the cut-off length of the billet butt.
