ABSTRACT:
A metal alloy, in particular a light alloy, is continuously cast in the semi-liquid state by bringing it up to conditions such as to cause segregation of a solid phase within the interior of the liquid alloy and making the alloy pass through a static mixer adapted to mix the solid phase uniformly upon formation, with the liquid alloy, so as to obtain at the output from the mixer a suspension which, once solidified, provides a material with valuable microstructural characteristics; the alloy is supplied continuously to the static mixer by introducing it in a discrete manner into a sealed furnace through an externally heated barometric column and, simultaneously, by pressurizing the interior of the furnace by the introduction into it of a flow of gas at a pressure value such as to cause the said alloy to flow through the static mixer in stationary laminar conditions.
