preparation example Construction

[0017] The invention relates to a method for preparing a high-purity aluminum alloy bus bar. The aluminum content in the aluminum alloy bus bar is ≥99.95% by weight, the nitrogen content is ≤0.001% by weight, the scandium content is 0.002-0.004% by weight, and the niobium content is 0.003-0.004% by weight, and the balance is unavoidable impurities.

[0018] Scandium has a low melting point (156.61°C), high boiling point (2080°C), good conductivity, good ductility, softer than lead, and can be scored with nails; strong plasticity, can be pressed into extremely thin metal sheets, and its nitrides Can form a transparent conductive film and other characteristics.

[0019] Niobium series elements are usually silvery-white lustrous metals that are relatively soft, ductile and paramagnetic. The chemical properties of niobium series elements are relatively active, and they are easy to change the crystal phase when smelting with other metal elements, and at the same time, they can pla...

[0021] Step 1. Smelting

[0022] Take 99.96kg of cathode aluminum, 0.003kg of scandium, and 0.004kg of niobium in a vacuum melting furnace, heat to 1100°C to form an aluminum alloy liquid, and cover the surface of the aluminum alloy liquid with a charcoal layer, so that the aluminum alloy liquid is always isolated from nitrogen;

[0023] Step 2, upward continuous casting

[0024] The graphite crystallizer is directly inserted into the molten aluminum, and the graphite crystallizer is cooled by a water spacer, and the aluminum alloy liquid is condensed into a solid in the graphite crystallizer, and the upper end of the solid is drawn by a drafting mechanism to make an aluminum alloy rod, which is continuously cast upwards When using charcoal to separate nitrogen, water jacket cooling;

[0025] Step three, continuous extrusion

[0026] The aluminum alloy rod obtained in step 2 is placed in an extrusion machine and continuously extruded into a billet;

[0027] Step 4. Cold dra...

Abstract

The invention relates to a preparation method of a high-purity aluminum alloy bus. The preparation method is characterized in that the aluminum alloy bus is prepared from the components in weight: more than or equal to 99.95 % of aluminum, less than or equal to 0.001 % of nitrogen, 0.002 to 0.004 % of scandium 0.003 to 0.004 % of niobium and the balance of being inevitable impurities. The preparation method comprises the following steps that cathode aluminum, scandium and niobium rare earth elements are placed in a vacuum smelting furnace, heating to form aluminum alloy liquid, and a charcoallayer is coated on the surface of the aluminum alloy liquid; a hollow crystallizer is directly extended into the aluminum liquid, the crystallizer is cooled by a water spacer sleeve, an aluminum alloyrod is formed by drawing through a drawing mechanism, and the aluminum alloy rod is placed in an extruder to be continuously extruded into a blank; and the blank is placed on a drawing machine to becold drawn and formed to form the aluminum alloy bus bar. The aluminum alloy bus manufactured by the preparation method can meet the requirement of high strength, and the conductivity of the aluminumalloy bus is improved.

Description

technical field [0001] The invention relates to an aluminum alloy busbar for a motor, in particular to a preparation method of a high-purity aluminum alloy busbar. It belongs to the technical field of electrical alloy materials. Background technique [0002] Aluminum bus bar is used to make motor electrical winding coils, high and low voltage electrical switch contacts and conductor materials for installation of power supply and distribution equipment. Aluminum busbars can be divided into soft aluminum busbars and hard aluminum busbars according to their uses. The traditional production process of aluminum busbar will make the aluminum liquid have the opportunity to contact with nitrogen during pouring, and the nitrogen content cannot be controlled. At the same time, the raw aluminum contains a large amount of impurities, which has a great impact on the conductivity, ductility and strength of the aluminum busbar. big impact. Contents of the invention [0003] The object...
