Embodiment 1
[0031] A kind of gong copper processing method of the present embodiment comprises the following steps:
[0032] Step 1: smelting of raw materials;
[0033] The raw materials are electrolytic copper, tin ingot, manganese alloy and zinc ingot. The raw materials are put into the melting furnace for melting. Electrolytic copper and tin ingot are added first, then manganese alloy, and finally zinc ingot. Do spectral analysis to check the content of Cu, Sn, Pb, and Mn elements, and finally control the mass percentage of Cu elements to 60.5-61%, the mass percentage of Sn elements to 0.8-1%, and the mass percentage of Mn elements to 0.035-0.05% , the mass percentage of Pb element is not more than 0.008%. When the content of each element meets the above standard requirements, the musical instrument reed made of gong copper can have more beautiful sound quality, which is more in line with the market's quality requirements for gong copper. Specifically, in this embodiment, the raw mate...
Embodiment 2
[0044] 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 0.05%, and the Pb element The mass percentage is 0.003%, and the annealing temperature in the roller hearth furnace is 650°C.
Embodiment 3
[0046] 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 0.04%, and the Pb element The mass percentage is 0.006%, and the annealing temperature in the roller hearth furnace is 640°C.
