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 ceramic particles is smelted in a smelting furnace , transferred to a ladle , degassed , and fed into a pressurized furnace 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 . at the outlet of the mixer the rheocast material is collected under laminar flow conditions , possibly with the interposition of a siphon type collecting tank and with protective gas shielding , through a cooled metal die , and solidified into a single billet . the billet is then guided by rollers past a saw and cut into pieces from which to obtain ingots of desired weight and size .
