Embodiment 1

[0032] A kind of gong copper of the present invention, the mass percentage of Cu element in gong copper is 60.5~61%, the mass percentage of Sn element is 0.8~1%, the mass percentage of Mn element is 0.025~0.035%, the mass percentage of Pb element is The percentage is not more than 0.008%. When the content of each element meets the requirements of the above standards, the musical instrument reed made of gong copper can have a more beautiful sound quality, which is more in line with the market's quality requirements for gong copper. Specifically in the present embodiment, the mass percentage of Cu element is 60.5%, the mass percentage of Sn element is 0.8%, the mass percentage of Mn element is 0.025%, and the mass percentage of Pb element is 0.008%. It is composed of electrolytic copper, tin ingot, Manganese alloys and zinc ingots are processed after smelting, and the specific processing steps are as follows:

[0033] Step 1: smelting of raw materials;

[0034] The raw material...

Embodiment 2

[0045] The present embodiment is the same as embodiment 1, and the difference is that the mass percentage of the Cu element in the gong copper of the present embodiment is 61%, the mass percentage of the Sn element is 1%, the mass percentage of the Mn element is 0.035%, and the Pb element The mass percentage is 0.003%, and the annealing temperature in the roller hearth furnace is 650°C.

Embodiment 3

[0047] The present embodiment is the same as embodiment 1, and the difference is that the mass percentage of the Cu element in the gong copper of the present embodiment is 60.8%, the mass percentage of the Sn element is 0.9%, the mass percentage of the Mn element is 0.03%, and the Pb element The mass percentage is 0.006%, and the annealing temperature in the roller hearth furnace is 640°C.

Abstract

The invention discloses sound spring copper, and belongs to the technical field of copper fabrication. The sound spring copper is manufactured by smelting and machining electrolytic copper, tin ingots, manganese alloy and zinc ingots. Finally, the mass percent of the Cu element is 60.5-61%; the mass percent of the Sn element is 0.8-1%; the mass percent of the Mn element is 0.025-0.035%; the mass percent of the Pb element is no more than 0.008%. The sound spring copper is manufactured by the following steps of smelting of raw materials, manufacturing of ingot blanks, hot rolling, edge cutting, cold rolling, inspection and storage. The specific cold rolling process is 2.1 mm-1.05 mm-0.85 mm-0.65 mm-0.5mm-0.39 mm-0.32 mm. According to the technical scheme, the problem that the Mn element is difficult to add can be effectively solved, and the sound spring copper with the good sound quality is obtained.

Description

technical field [0001] The invention relates to the technical field of copper processing, and more specifically, relates to a special gong copper for musical instruments. Background technique [0002] Gong copper is a kind of brass product specially used as musical instrument reed. In order to meet the special requirements of this musical instrument for timbre and the internal quality requirements of environmental protection and non-toxicity of the product, gong copper must be used on the basis of environmentally friendly brass belt products. In addition, adding a certain proportion of manganese can meet the basic requirements of this type of instrument. However, the difficulties in the production of gong copper mainly lie in: (1) when, how, and how much manganese is added; (2) how to transition to subsequent products after smelting and producing gong copper, and how to ensure that the influence of manganese is eliminated Reduce it to a controllable range to ensure the qual...
