A process for semiliquid casting ingots from which to produce high-mechanical-performance die castings, whereby a metal alloy in the form of pigs and containing or not ceramic particles is smelted in a smelting furnace (2), transferred to a ladle (3), degassed, and fed into a pressurized furnace (6) from which it is cast in the semiliquid state by feeding it at the solidification stage and under laminar flow conditions into a static mixer (12), at the outlet of which the rheocast material is collected under laminar flow conditions, possibly with the interposition of a siphon type collecting tank (23) and with protective gas shielding, through a cooled metal die (20), and solidified into a single billet (41), which is then guided by rollers (25) past a saw (26) and cut into pieces from which to obtain ingots of desired weight and size. <IMAGE> <IMAGE> |
