Embodiment 1

[0031] A method for making copper murals includes the following steps:

[0032] Step 1: Use a wooden board with a thickness of 10 mm to make a rectangular wooden box with an open upper end as a wooden mold for casting; the cavity size of the wooden mold is: length 1000 mm, width 5 mm, and height 500 mm.

[0033] Step 2: Heat and melt a mixture of copper scraps (brass scraps), low-melting metal tin, aluminum, and flux boron to obtain a casting solution. The amount of tin is 1% of the weight of copper scraps, and the amount of aluminum is copper scraps 0.5% by weight, the amount of borax is 0.2% by weight of copper scraps.

[0034] Step 3: Immerse the wooden mold in water for 1 minute, then take out the wooden mold and pour out the water in the wooden mold.

[0035] Step 4: Pour the casting liquid slowly from the opening at the upper end of the wooden mold into the cavity of the wooden mold. The casting liquid is poured into the cavity of the wooden mold at one time, and the copper mate...

Embodiment 2

[0039] A method for making copper murals includes the following steps:

[0040] Step 1: Using a wooden board with a thickness of 15mm to make a rectangular wooden box with an open upper end as a wooden mold for casting; the cavity size of the wooden mold is: length 2000mm, width 15mm, and height 1200mm.

[0041] Step 2: Heat and melt a mixture of copper scraps (brass scraps), low-melting metal tin, aluminum, and flux boron to obtain a casting liquid. The amount of tin is 2% of the weight of copper scraps, and the amount of aluminum is copper scraps 1.5% by weight, and borax is 0.5% by weight of copper scraps.

[0042] Step 3: Immerse the wooden mold in water for 3 minutes, then take out the wooden mold and pour out the accumulated water in the wooden mold.

[0043] Step 4: Pour the casting liquid slowly from the upper opening of the wooden mold into the cavity of the wooden mold. The casting liquid is poured into the cavity of the wooden mold three times, and the copper material is po...

Embodiment 3

[0047] A method for making copper murals includes the following steps:

[0048] Step 1: Use a board with a thickness of 12 mm to make a rectangular wooden box with an open upper end as a wooden mold for casting; the cavity size of the wooden mold is: length 1900 mm, width 12 mm, and height 1000 mm.

[0049] Step 2: Heat and melt a mixture of copper scraps (brass scraps), low-melting metal tin, aluminum, and flux boron to obtain a casting liquid. The amount of tin is 1.5% of the weight of copper scraps, and the amount of aluminum is copper scraps 1% by weight, borax dosage is 0.3% by weight of copper scraps.

[0050] Step 3: Immerse the wooden mold in water for 2 minutes, then take out the wooden mold and pour out the accumulated water in the wooden mold.

[0051] Step 4: Pour the casting liquid slowly from the upper opening of the wooden mold into the cavity of the wooden mold. The casting liquid is poured into the cavity of the wooden mold three times, and the copper material is pour...

Abstract

The invention discloses a copper mural manufacturing method. Leftover materials of copper materials are utilized for manufacturing a copper double-face mural with the double faces with naturally-formed pattern texture. The technology is simple and easy to implement and is suitable for industrial production, pollution is little in the production process, the specialty requirement for operators is low, and the production efficiency is high. The surface pattern texture of the copper mural is not pre-designed or pre-manufactured and is formed in real time when high-temperature fusion materials anda wood board wall are in interaction during casting, the characteristics of natural texture, soft pictures and the like are achieved, the double faces both have the characteristics, and very high artexpressive force is achieved.

Description

Technical field [0001] The invention relates to the technical field of metal crafts processing, in particular to a method for making copper murals. Background technique [0002] Existing copper murals are mostly made by forging or etching on a whole copper plate, and then by post-coloring treatment, etc. The patterns, patterns, levels, etc. on the surface are generally designed in advance, and general patterns Only one-sided. For example, ZL201620222752.7 "a three-dimensional copper mural" expresses a three-dimensional copper mural, but the patterns used on the levels are also presented by traditional methods of etching or forging. The problems of the etching process are: the use of strong acid or alkali etching, the process is complicated, and the pollution is large; the problems of the forging process are: manual operation, time-consuming, low production efficiency, and high requirements for the operator's professionalism. In addition, neither the etching process nor the forg...
