New Billet Mould Casting Technology
The aluminum billet casting industry is continually looking for reliable, simple and efficient ways to produce high quality, aluminum billet stock for the extrusion and forging industry. Current demands for billet quality requires that the billet have a very thin inverse segregation of less than 250 microns, uniform cell size of less than 30 microns depending on the alloy, average grain size of less than 130 microns, dendrite arm spacing of less than 50 microns and is crack free. The characteristics of the mould technology needed to achieve the required metallurgical quality economically are described in this paper.
