Abstract

An embodiment in accordance with the present invention provides a method for the production of castings with incorporated tubes, where the castings are from cast metal and where the tubes are cast-in with a superheated molten metal. Multiple tubes or a plurality of designs may be incorporated into the invention. The present invention also provides a method for cooling the interior of a cast product before, during, and after the product is cast.

Claims

1. A method for production of a casting incorporating a passage comprising:

disposing at least one tube in a mold to form the passage; and

casting a metal around the tube, wherein a portion of the tube is deformed during casting.

2. The method according to claim 1, wherein the metal is a semi-solid metal.

3. The method according to claim 1, wherein the tube comprises steel.

4. The method according to claim 1, wherein the mold comprises guides matching the direction of the tube through the casting.

5. The method according to claim 1, wherein the metal is an aluminum alloy.

6. The method according to claim 1, wherein the portion of the tube is crimped or clamped.

7. The method according to claim 1, further comprising treating at least a portion of a surface of the tube.

8. The method according to claim 7, wherein the treating comprises spraying the surface with an aluminum composition.

9. The method according to claim 7, wherein the treating comprises shot blasting.

10. The method according to claim 7, wherein the treating comprising metal plating.

11. The method according to claim 1, further comprising passing fluids through the tube before, during, or after casting.

23. The method according to claim 1, wherein the tube comprises aluminum.

24. The method according to claim 1, wherein the metal is a liquid metal.

25. The method of claim 1, wherein the casting is hollow.

26. The method of claim 1, wherein the mold comprises openings to pass a cooling medium through the casting.

27. The method of claim 1, wherein the casting is steel or aluminum.

12. A means for production of a casting incorporating a passage comprising:

disposing means that places at least one tube in a mold; and

a casting means that casts a metal around the tube.

13. The casting means according to claim 12, wherein the metal is a semi-solid metal.

14. The casting means according to claim 12, wherein the tube comprises steel.

15. The casting means according to claim 12, wherein the mold comprises guides matching the direction of the tube through the casting.

16. The casting means according to claim 12, wherein the metal is an aluminum alloy.

17. The casting means according to claim 12, wherein the tube is crimped or clamped.

18. The casting means according to claim 12, further comprising treating at least a portion of a surface the tube.

19. The casting means according to claim 18, wherein the treating comprises spraying the surface with an aluminum composition.

20. The casting means according to claim 18, wherein the treating comprises shot blasting.

21. The casting means according to claim 18, wherein the treating comprising metal plating.

22. A cast product, comprising:

at least one tube; and

metal cast around the tube.

28. A method for production of a casting incorporating a passage comprising:

disposing a tube in a mold to form the passage, the tube having a first end and a second end;

closing the tube at the first or second end;

deforming a portion of the tube during casting; and

casting a metal around the tube to form a product.

29. The method according to claim 28, wherein the second end is closed during casting and is opened after casting by a metal treatment.

30. The method according to claim 28, wherein a cooling medium is disposed in the tube.
