Problems solved by technology

[0010] In view of the poor fluidity of the existing technology, it is not suitable for precision forging, especially it is not suitable for processing handicrafts with small diameters such as dragon whiskers, which not only limits the progress of cultural artworks, but also increases production costs. The present invention provides a Copper alloy for investment casting of artworks and preparation method and method for precision casting capable of casting artworks with a minimum diameter of 1mm

Embodiment 1

[0054] A method for processing copper alloys for precision casting of works of art, the steps are:

[0055] (1) First add Cu with a mass fraction of 47.0% into the crucible to melt and heat to 1098°C;

[0056] (2) Grinding Fe with a mass fraction of 1.5% into a powder with a diameter of 9-15nm for later use;

[0057] (3) Sb film with a mass fraction of 3.7% is made into a Sb film with a thickness of 0.3mm, and Te powder with a mass fraction of 0.3% is wrapped with the Sb film, and the particle size of the Te powder is 5-10nm;

[0058] (4) Add Bi with a mass fraction of 3.5%, Ni with a mass fraction of 1.0%, and Fe powder in step (2) to the crucible in step (1) in sequence, and when heated to 1105°C, add Zn and keep the temperature No change, stop heating after the Zn is completely melted, and immediately put the Sb film wrapped with Te powder obtained in step (3) to obtain the alloy melt;

[0059] (5) Cool the melt obtained in step (4) in air at a cooling rate equal to 15°C ...

Embodiment 2

[0062] Same as Example 1, the difference is: its composition and mass percentage content are: Cu: 45.0, Sb: 3.9%, Fe: 1.3, Bi: 4.0%, Ni: 0.5%, Te: 0.5%, and the balance is Zn ; The cooling rate per second in step (5) is equal to 13°C. The fluidity of this alloy is 114mm.

Embodiment 3

[0064] Same as Example 1, the difference is: its composition and mass percentage content are: Cu: 49.0%, Sb: 3.5%, Fe: 1.7%, Bi: 3.0%, Ni: 1.5%, Te: 0.2%, the balance is Zn; the cooling rate per second in step (5) is equal to 13°C. The fluidity of this alloy is 115mm.

Abstract

The invention discloses a copper alloy for precision casting of artwork, and a preparation method and a method for precision casting, and belongs to the field of precision casting. The copper alloy comprises the following components by mass percent: 45.0-49.0% of Cu, 3.5-3.9% of Sb, 1.3-1.7% of Fe, 3.0-4.0% of Bi, 0.5-1.5% of Ni, 0.2-0.5% of Te and the balance of Zn, wherein the sum of Sb and Te is smaller than or equal to 4.2%. The mobility of the alloy disclosed by the invention is greatly improved, and the method is applicable to casting of cultural artifacts. The artwork of which the minimal diameter is about 1mm can be cast, the casting accuracy is improved, and the application field of the casting technique is expanded. A processing method of the copper alloy for precision casting of the artwork and a method for precision casting are also disclosed by the invention.

Description

technical field [0001] The invention belongs to the field of precision casting, in particular, relates to a copper alloy for precision casting of works of art and a casting method, more specifically, relates to a copper alloy for precision casting of works of art, a preparation method and a copper alloy for precision casting Methods. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for spiritual culture are getting higher and higher, especially the demand for artworks is showing an expansive growth. As a special commodity, art has the basic attributes of commodities - use value and value. Artwork as a commodity is different from ordinary commodities. Its use value is not manifested as a material tool, but embodied in spirit and culture—to satisfy people's aesthetic and spiritual needs. Therefore, human subjective factors will play a decisive role in the formation of the use value of artworks. The value of wo...
