<p>A method for bringing aluminium alloy blocks, such as ingots, billets and others to a semi-solid and semi-liquid state which allows them to be moulded, according to which there is a first phase for refining the said aluminium alloy by adding a silicon-boron alloy to the said aluminium alloy when it is melted, a second phase for heating the said ambient temperature blocks until a temperature is reached in which there is a balance between its solid and liquid states and in which the phases of eutectic silicon are liquid and the phases of α-aluminium are solid and a third operating phase for using the said alloy blocks obtained in the previous phases inside the moulding system in the semi-solid and semi-liquid state, through which the resulting semi-finished products are obtained.</p> |
