Example Embodiment
[0038] Example 1
[0039] A kind of impurity remover for copper alloy smelting, which is made by mixing the following mass percentage of raw materials: 10% Eu 2 O 3 Powder, 5% Rb 2 O 2 Powder, 5% SiO 2 Powder, 3% TiO 2 Powder, 5% Na 2 SiF 6 Powder, 15% Na 2 CO 3 Powder, the balance is Na 2 B 4 0 7 powder;
[0040] According to the ratio in Example 1, various industrially pure powders were mixed uniformly by a mechanical method, then compressed into a block by a tablet press, and then tightly covered with a thin copper skin.
[0041] When the copper alloy is smelted, after all the alloy raw materials are melted, the temperature of the melt is raised to the melting temperature, and then left to stand for 10 minutes for slagging; then the pre-prepared impurity remover in Example 1 is added, and the impurity remover is pressed Into the melt, the impurity remover pressed into a block will melt slowly and will not be quickly lost. The impurity remover has sufficient contact time with the m...

[0043] Example 2
[0044] A kind of impurity remover for copper alloy smelting, which is made by mixing the following mass percentage of raw materials: 20% Eu 2 O 3 Powder, 10% Rb 2 O 2 Powder, 12% SiO 2 Powder, 4% TiO 2 Powder, 7% Na 2 SiF 6 Powder, 17% Na 2 CO 3 Powder, the balance is Na 2 B 4 0 7 powder;
[0045] According to the ratio in Example 2, various industrially pure powders were mixed uniformly by a mechanical method, and then compressed into a block by a tablet machine, and then tightly covered with a thin copper skin.
[0046] When the copper alloy is smelted, after the alloy raw materials are all melted, the temperature of the melt is raised to the melting temperature, and then left to stand for 10 minutes for slagging; then the pre-prepared impurity remover in Example 2 is added, and the impurity remover is pressed Into the melt, the impurity remover pressed into a block will melt slowly and will not be quickly lost. The impurity remover has sufficient contact time wi...

[0048] Example 3
[0049] A kind of impurity remover for copper alloy smelting, it is made by mixing the following mass percentage of raw materials: 25% Eu 2 O 3 Powder, 15% Rb 2 O 2 Powder, 15% SiO 2 Powder, 5% TiO 2 Powder, 10% Na 2 SiF 6 Powder, 20% Na 2 CO 3 Powder, the balance is Na 2 B 4 0 7 powder;
[0050] According to the ratio in Example 3, various industrially pure powders were mixed uniformly by a mechanical method, then compressed into a block by a tablet machine, and then tightly covered with a thin copper skin.
[0051] When the copper alloy is smelted, after all the alloy raw materials are melted, the temperature of the melt is raised to the melting temperature, and then left to stand for 10 minutes to remove the slag; then the pre-prepared impurity remover in this example 3 is added, and the impurity remover is pressed Into the melt, the impurity remover pressed into a block will melt slowly and will not be quickly lost. The impurity remover has sufficient contact ti...
