Metal with solids

Abstract

A method for producing metals or metal alloys includes melting, by a melting apparatus, a metal or a metal alloy to produce a casting melt, transporting, by a feed line, the casting melt to casting moulds to be filled, adding, during the transporting of the casting melt by the feed line, solids to the casting melt, and mixing the casting melt with the added solids in a mixing zone during the transporting of the casting melt by the feed line.

What is claimed is: 
     
         1 . A method for producing metals or metal alloys, the method comprising:
 melting, by a melting apparatus, a metal or a metal alloy to produce a casting melt;   transporting, by a feed line, the casting melt to casting moulds to be filled,   adding, during the transporting of the casting melt by the feed line, solids to the casting melt; and   mixing the casting melt with the added solids in a mixing zone during the transporting of the casting melt by the feed line.   
     
     
         2 . The method according to  claim 1 , wherein the mixing is carried out during and/or after the addition of the added solids. 
     
     
         3 . The method according to  claim 1 , wherein the mixing is carried out in the mixing zone by an ultrasound sonotrode, and wherein the casting melt and the added solids are excited by ultrasound. 
     
     
         4 . The method according to  claim 1 , wherein supply of the casting melt in the feed line takes place continuously. 
     
     
         5 . The method according to  claim 1 , wherein the added solids are fibres and/or particles. 
     
     
         6 . The method according to  claim 5 , wherein the fibres include one or more of carbon fibres, aluminium oxides, basalt, silicon carbide, aramid, metal fibres, coated fibres and/or derivatives thereof. 
     
     
         7 . The method according to  claim 1 , wherein the feed line is thermally regulated. 
     
     
         8 . The method according to  claim 1 , wherein the casting melt is cooled during the transporting in the feed line until the casting melt has a semisolid state. 
     
     
         9 . The method according to  claim 8 , wherein the added solids are kneaded in the casting melt in the semisolid state in the mixing zone. 
     
     
         10 . A device for producing metals or metal alloys, the device comprising:
 a melting apparatus configured to melt a metal or a metal alloy;   a feed line;   a dosing system configured to add solids into the casting melt, the dosing system being connected to the feed line, and   a mixer configured to perform homogeneous mixing of the casting melt, the mixer being arranged on the feed line and the mixing of the casting melt being carried out during transport of the casting melt.   
     
     
         11 . The device according to  claim 10 , wherein the mixer is an ultrasound sonotrode. 
     
     
         12 . The device according to  claim 10 , wherein a pump configured to deliver the casting melt is arranged on the feed line. 
     
     
         13 . The device according to  claim 10 , wherein the feed line comprises a bypass line configured to permit a plurality of passes of the casting melt through an introduction and mixing zone. 
     
     
         14 . The device according to  claim 10 , wherein the dosing system comprises an injector configured to introduce the solids into the casting melt. 
     
     
         15 . The method according to  claim 1 , further comprising using the metal or the metal alloy for the production of cast parts.
