Embodiment 1

[0028]The method of separating Al-Sn-Cu ternary alloy by supergravity, first heating the Al-Sn-Cu ternary alloy to 700 ~ 1000 ° C, ensuring that the aluminum and tin are liquid, the copper is still solid, and then poured into the centrifuge, the supergravity coefficient is set to 0 ~ 150G, the supergravity separation can be achieved, the separation of Al-Sn and Cu can be realized; continue to cool the Al-Sn alloy to 300 ~ 600 ° C, to ensure that the tin is liquid, and the aluminum is condensed into a solid state. And the supergravity coefficient is adjusted to 150~300G, and then the supergravity separation is performed, and the Al-Sn separation can be realized.

[0029] The specific steps are as follows:

[0030] Step 1: First, the 0.5kg Al-Sn-Cu ternary alloy (containing 80.6% aluminum, 17.1% tin, and 2.3% copper) is heated to 700 °C, so that aluminum and tin are liquid, and copper remains solid.

[0031] Step 2: Pour the Al-Sn-Cu ternary alloy into the centrifuge, set the superg...

Abstract

The invention discloses a method for separating the Al-Sn-Cu ternary alloy by supergravity. First, the Al-Sn-Cu ternary alloy is heated to 700-1000°C to ensure that the aluminum and tin are in a liquid state and the copper is still in a solid state, and then Pour it into a centrifuge, set the supergravity coefficient to 0~150G, and carry out supergravity separation to realize the separation of Al‑Sn and Cu; continue to cool the Al‑Sn alloy to 300~600 °C to ensure that tin becomes liquid and aluminum Al-Sn can be separated by condensing into a solid state and adjusting the super-gravity coefficient to 150-300G for super-gravity separation. The invention realizes the effective separation of the Al-Sn-Cu ternary alloy by using supergravity. The process is a physical process, and has the advantages of high efficiency, low energy consumption, environmental friendliness, simple operation, high universality, and easy industrialization.

Description

Technical field [0001] The present invention belongs to the field of non-ferrous metal pyrocene smelting technology, specifically, relates to a method of supergravity separation of Al-Sn-Cu ternary alloys. Background [0002] As a symbol of modern material civilization, the automobile has brought great changes to human life, but with the vigorous development of the automobile industry, waste cars have also produced huge negative pressure on the living environment of human beings, of which waste car engines are the mainstay. As the core component of the automobile, the engine faces the challenge of recycling in the process of building the green industrial chain of the automobile, and the impact of the engine on resources, energy and the environment is the first problem that should be clarified by green development. In order to alleviate the contradiction between resource shortage and resource waste, reduce the harm to the environment of a large number of scrapped car engines, and ...
