ABSTRACT:
A method by which ingots of thixotropic metal alloy are brought to the semisolid or semiliquid state comprises the steps of introducing the single solid ingots at ambient temperature into a heat chamber, generating air currents within the chamber so that the ingots are heated principally by convection, controlling the temperature of the ingots, and removing them from the chamber once a predetermined temperature has registered and been held steady in the metal alloy for a duration sufficient to induce the semisolid or semiliquid state; the ingots are supported and conveyed through a circular path internally of the heat chamber by a set of radial platforms revolving between an infeed zone and an outfeed zone.
