Production of semisolid slurry with two or more stirring devices

A method for producing a semisolid metal slurry, comprising the steps of:

• providing at least two stirring devices, each having a first end and an opposite second end defining a central axis therebetween, wherein onto each first end a cast metal piece is attached;
• inserting the first end of each of the at least two stirring devices into a liquid metal bath such that each cast metal piece is submerged in the liquid metal bath;
• after insertion of the at least two stirring devices into the liquid metal bath, simultaneously rotating the at least two stirring devices with the attached cast metal piece around their respective central axis, and thereby rotating said cast metal pieces in the liquid metal bath;
• wherein the rotation is continued at least until a majority of the cast metal pieces are molten, such that a semisolid metal slurry is produced.

An arrangement for producing a semisolid metal slurry, comprising:

• at least two stirring devices, each having a first end and an opposite second end defining a central axis therebetween, and wherein each of the at least two stirring devices comprises a cast metal piece attached onto each first end;
• and
• a stirring apparatus arranged for:
• inserting the first end of each of the at least two stirring devices into a liquid metal bath such that each cast metal piece is submerged in the liquid metal bath;
• after insertion of the at least two stirring device into the liquid metal bath, simultaneously rotating the at least two stirring devices with the attached cast metal piece around their respective central axis, and thereby rotating said cast metal pieces in the liquid metal bath;
• wherein the rotation is continued at least until a majority of the cast metal pieces are molten, such that a semisolid metal slurry is produced.
