Abstract

The invention discloses an electronic-grade ultra-high-purity aluminum crystallization device. The electronic-grade ultra-high-purity aluminum crystallization device comprises a rotating body and a driving device; the rotating body is installed above a crucible; the lower end of the rotating body extends into the position below the liquid level of molten aluminum in the crucible; the driving device is connected with the rotating body and is used for driving the rotating body to rotate; a cooling gas circuit is arranged in the rotating body and is filled with cooling gas to cool the rotating body, and then high-purity aluminum crystals are formed at the lower end of the rotating body through solidification and accumulation. The electronic-grade ultra-high-purity aluminum crystallization device solves the problems of high purification cost and poor purification effect in the prior art.

Description

technical field [0001] The invention relates to a purification device for metal aluminum, in particular to an electronic-grade ultra-high-purity aluminum crystallization device. Background technique [0002] Aluminum products with a purity above 5N5 are called ultra-high-purity aluminum. Ultra-high-purity aluminum is widely used in the fields of electronics, aviation, navigation, chemical and defense industries, and its consumption is increasing year by year. But now there are very few domestic enterprises that can produce 5N5 ultra-high-purity aluminum that meet the needs of users, and there are only a handful of research and development units. Therefore, almost all ultra-high-purity aluminum needed in China depends on imports. [0003] In the prior art, such as the invention patent application document with the application number 201610042682.1, a method for purifying ultra-high-purity aluminum is proposed, including selecting refined aluminum with a purity of at least 4N6...
