ABSTRACT:
A process for the preparation of a mixture comprising a solid phase and a liquid phase of a metal alloy, in which the concentration of the said solid phase has a pre-established value, is described; it comprises at least a first stage for bringing the said alloy into a completely fluid state, a second stage for creating a constant range flow of the mixture between an inlet section and an outlet section, a third stage for subdividing in a longitudinal direction the said flow into a plurality of flow sections, each of which has a predetermined length and in each of which the flow is subdivided into at least two independent streams, and a fourth stage for making each of the said streams flow along such a trajectory as to obtain in each of the said streams of each flow section a confluence of parts of both streams of the immediately preceding section.
