Description

Technical Field

[0001] The invention relates to the technical field of brass and brass alloy production, and in particular to a melting, casting and refining device and method. Background Art

[0002] During the smelting process of copper and its alloys, the molten copper has the property of absorbing gas, which is one of the main characteristics of the smelting of copper and its alloys and also a technical difficulty in the production of copper and copper alloys. In a low-temperature environment, the viscosity of the molten copper is large, and the gas is adsorbed in the molten copper and cannot float up. During high-temperature reduction refining, as the oxygen content in the molten copper drops to a certain limit, the molten copper again absorbs other gases from the smelting atmosphere, causing the gas content to increase sharply. Therefore, how to ensure that there is no gas content in the molten copper is a technical difficulty in the production of copper and copper alloys.

[0003] The existing production process of copper and copper alloy products uses vacuum induction furnaces, but this process has high equipment investment and high production costs, resulting in high final product costs; most products, such as brass products, are still produced by smelting in open induction furnaces, which have the advantages of low equipment investment and low production costs, but also have the disadvantage of not being able to produce high-quality products. During the smelting process of brass products, impurities inside the solution will precipitate and float to produce a large amount of slag. When smelting at low temperatures, the melt has high viscosity, and the precipitated impurities cannot float quickly, and are sandwiched in the middle of the melt to form slag, resulting in unqualified ingot quality. To this end, we propose a melting and refining device and method. Summary of the invention
