<p>A metal alloy (2), 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 (3) 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 (3) by introducing it in a discrete manner into a sealed furnace (1) through an externally heated barometric column (10) and, simultaneously, by pressurising the interior of the furnace (1) 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 (3) in stationary laminar conditions.</p> |
