Abstract

The invention discloses a preparation method of an aluminum ingot. The preparation method comprises the steps of providing electrolytic primary aluminum liquid; obtaining the mass contents of vanadiumand titanium in the electrolytic primary aluminum liquid; according to the mass contents of vanadium and titanium in the electrolytic primary aluminum liquid, obtaining the mass of boron needing to be added to the electrolytic primary aluminum liquid every preset quality; providing a mass content change graph which shows the change of the mass content sum of vanadium and titanium along with the addition amount of boron; determining the optimal addition amount of an aluminum-boron intermediate alloy according to the mass content change graph; adding the aluminum-boron alloy to the electrolyticprimary aluminum liquid for smelting, and after stirring, standing is carried out for preset time; and taking an on-the-spot sample for chemical component analysis, and after the chemical component analysis result meets the requirement, opening a hearth of a mixing furnace for ingot casting operation. The preparation method has the following advantages: the low-vanadium low-titanium aluminum ingot product can be prepared, and under the broad environment of cost reduction and efficiency improvement, high-efficiency production of the low-vanadium low-titanium aluminum ingot is achieved throughthe ingot casting mixing furnace by optimizing the process and adjusting the production structure.

Description

technical field [0001] The invention relates to the technical field of producing aluminum ingots, in particular to a method for preparing aluminum ingots. Background technique [0002] With the development of industry, aluminum for electrical purposes has been widely used, extending to high-end fields such as motor rotors. Therefore, higher requirements are put forward for the quality of aluminum ingots for electrical purposes. [0003] The primary aluminum ingot often contains a certain amount of trace elements such as V and Ti in the form of solid solution, and these elements have a very adverse effect on the conductivity of the aluminum conductor. Trying to reduce the content of Ti, V and other elements is a problem that needs to be solved to further improve the conductivity of aluminum conductors. Non-metallic element B has a strong binding force with V, Ti and other elements, and can form VB with high melting point and higher density than aluminum 2 、TiB 2 Wait for b...
