System and mixing arrangement for preparing an aluminium melt

A system of obtaining an aluminium melt including SiC particles for use when moulding vehicle parts, the system comprises:

• a pre-processing tank, configured to receive SiC particles and to apply a pre-processing procedure to pre-process the SiC particles;
• a SiC particle transport member configured to transport the pre-processed SiC particles from the pre-processing tank to a crucible of a melting furnace device, and
• the melting furnace device is configured to receive and melt solid aluminium, and to hold the aluminium melt and to receive said pre-processed SiC particles, wherein said system also comprises a tube-like SiC particle mixing arrangement defining an enclosure for an elongated mixing chamber, the mixing arrangement is configured to be mounted in said crucible such that, it is in an essentially vertical position, and that the mixing arrangement is elongated along a longitudinal axis A and structured to receive into said mixing chamber said pre-processed SiC particles via a first inlet and said aluminium melt via at least one second inlet, and to apply a mixing procedure by rotating a rotatable mixing member arranged in said mixing chamber about said longitudinal axis A, wherein said pre-processed SiC particles are mixed together with the aluminium melt in said mixing chamber,
• and wherein said mixing member is configured to cooperate with an inner wall surface of the mixing chamber resulting in that mechanical shear forces obtained between the mixing member and the inner wall surface during rotation submitted to the SiC particles and aluminium melt result in high wetting of SiC particles in the aluminium melt and that said mixing member is structured to provide movement forces to said mixture of aluminium melt and SiC particles, and wherein said mixing arrangement is provided with at least one outlet to feed out the mixture from said mixing chamber into said crucible;
• wherein SiC particle mixing arrangement comprises an elongated housing having a housing wall defining said mixing chamber, and wherein the housing comprises a first body part and a second body part;
• and
• wherein said housing wall has a cylinder-like shape having an essentially circular cross-section, and wherein said first inlet and said at least one second inlet are arranged in said second body part, and said at least one outlet is arranged in said first body part, and wherein, the mixing arrangement is configured to be submersed into said aluminium melt such that said first inlet is above said aluminum melt and said at least one second inlet is submersed into said aluminium melt.
