In particular applications (e.g. precision foundry, lost wax micro fusion), and in particular for certain special alloys, protecting the surface of the metal bath with a layer of liquid gas (Ar, N2) makes it possible to effectively reduce gas inclusion due to contaminants, and to reduce the formation of slag due to oxidation of the bath, and the loss of important alloying elements (e.g. Ni, Ti, Co, Cr…) thus avoiding the necessary adjustments. The production of waste due to defects, and the resulting cost of finishing the castings, is thus considerably reduced.
SOL, thanks to its cooperation with highly-qualified partners and to its many years of experience in Italy and Europe, can offer its customers effective, made-to-measure cryogenic gas distribution systems that minimise the problems caused by gas loss and ensure constant flows of liquid.
