Abstract: A system of obtaining an aluminium melt including SiC particles for use when moulding vehicle parts, e.g. brake disks. The system comprises a pre-processing tank (2),configured to receive SiC particles and to apply a pre-processing procedure to pre-process the SiC particles; a SiC particle transport member (4) configured to transport the pre-processed SiC particles from the pre-processing tank (2) to a crucible (6) of a melting furnace device (8), and that the melting furnace device (8) is configured to receive and melt solid aluminium, e.g. aluminium slabs, and to hold an aluminium melt (10) and to receive said pre-processed SiC particles (12). The pre-processing tank (2) is a fluidization tank, and that said pre-processing procedure is a fluidization procedure including heating and fluidizing of said SiC particles. The fluidization procedure is performed during a predetermined time period, and that said heating comprises heating said SiC particles up to at least 400° C., in order to achieve a protective oxide layer around said SiC particles.

The system also comprises a tube-like SiC particle mixing arrangement (14) defining and enclosing an elongated mixing chamber (16), the mixing arrangement (14) is configured to be mounted in said crucible (6) and structured to receive into said mixing chamber (16) said pre-processed SiC particles (12) via a first inlet (18) and said aluminium melt (10) via at least one second inlet (20), and to apply a mixing procedure by rotating a rotatable mixing member (22) arranged in said mixing chamber (16) about said longitudinal axis A, wherein said pre-processed SiC particles are mixed together with the aluminium melt in said mixing chamber. The mixing arrangement (14) is provided with at least one outlet (26) to feed out the mixture from said mixing chamber into said crucible.
