Embodiment 1

[0039] A impurity remover for copper alloy smelting, which is mixed with the following raw materials in mass percentage: 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 proportion in Example 1, the powders of various industrial pure grades were mixed uniformly by mechanical means, then compressed into a block by a tablet press, and then covered tightly with a thin copper skin.

[0041] When the copper alloy is smelted, after the alloy raw materials are completely melted, the temperature of the melt is raised to the smelting temperature, and then left to stand for 10 minutes to remove slag; When the impurity remover is put into the melt, the impurity remover pressed into agglomerates will melt slowly, so that it will not be lost quickly. The impurity remover and the melt have sufficient contact time. When fine scum appears on the surface...

Embodiment 2

[0044] A impurity remover for copper alloy smelting, which is mixed with the following raw materials in mass percentage: 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 proportion in Example 2, the powders of various industrial grades were mechanically mixed uniformly, then compressed into a block by a tablet press, and then covered tightly with a thin copper sheet.

[0046] When the copper alloy is smelted, after the alloy raw materials are completely melted, the temperature of the melt is raised to the smelting temperature, and then left to stand for 10 minutes to remove slag; When the impurity remover is put into the melt, the impurity remover pressed into agglomerates will melt slowly, so that it will not be lost quickly. The impurity remover and the melt have sufficient contact time. When fine scum appears on the surface of the...

Embodiment 3

[0049] A impurity remover for copper alloy smelting, which is mixed with the following raw materials in mass percentage: 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 proportion in Example 3, the powders of various industrial grades were mechanically mixed uniformly, then compressed into a block by a tablet press, and then covered tightly with a thin copper sheet.

[0051] When the copper alloy is smelted, after the alloy raw materials are completely melted, the temperature of the melt is raised to the smelting temperature, and then left to stand for 10 minutes to remove slag; When the impurity remover is put into the melt, the impurity remover that is pressed into blocks will melt slowly, so that it will not be lost quickly. The impurity remover and the melt have sufficient contact time. When fine scum appears on the surface of ...

Abstract

The invention provides an impurity removing agent for smelting a copper alloy. The impurity removing agent is formed by mixing the following raw materials by weight: 10% to 30% of Eu2O3 powder, 5% to15% of Rb2O2 powder, 5% to 20% of SiO2 powder, 1% to 5% of TiO2 powder, 5% to 10% of Na2SiF6 powder, 15% to 20% of Na2CO3 powder and the balance Na2B4O7 powder. The invention further provides an application method of the impurity removing agent for smelting the copper alloy. According to the impurity removing agent provided by the invention, on the one hand, the formula of the impurity removing agent is optimized and improved; the raw materials in the formula are used for physically removing and chemically removing impurities; on the other hand, the application method of the impurity removingagent is optimized and improved to form a powerful combination situation; and due to the combination, the removal effect of trace impurity elements and nonmetal impurities existing in molten liquid ina smelting process of the copper alloy is finally improved.

Description

technical field [0001] The invention relates to the technical field of copper processing, in particular to an impurity remover for copper alloy smelting and a use method thereof. Background technique [0002] With the continuous development of science and technology, the market's quality requirements for copper alloy products continue to increase. How to improve the quality of copper alloy products and better adapt to market demand is the biggest issue faced by various copper processing plants. [0003] Domestic enterprises produce copper alloys, and the raw materials are used in combination with new materials, leftover materials, old materials, etc. The recycling of raw materials has caused the continuous accumulation of impurities in the melt, resulting in fluctuations in the quality of copper alloy products. [0004] In order to reduce the impact of impurity elements in the copper alloy on the product quality, in the smelting process, the molten metal is subjected to corr...
