Abstract

The invention provides a preparation method of molten aluminum. The preparation method comprises the following steps of A, placing an aluminum material in a crucible for heating and melting, and heating to 700 - 710 DEG C to obtain molten liquid; B, adding a fluxing medium into the molten liquid, and carrying out uniform stirring; C, removing scum; D, continuously introducing inert gas into the molten liquid while stirring the molten liquid by using a stirrer, and adding 0.15 - 0.25% mass ratio of a refining agent and 0.01 - 0.016% mass ratio of strontium into the molten liquid; E, stopping stirring after the stirring time of the stirrer reaches a first preset time, and removing the scum; and F, after the molten liquid is heated to 720 +/-10 DEG C, carrying out standing according to secondpreset time, and obtaining the final molten aluminum. When the method is used for preparing the molten aluminum, potential safety hazards and production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for preparing molten aluminum. Background technique [0002] In the prior art, when preparing molten aluminum, it is usually necessary to add a modifier. In the general preparation process, sodium (referring to simple sodium, usually sodium block) is often used as a modifier. However, the price of sodium is relatively high. Moreover, it is not easy to store, and it is prone to explosion after contact with water and has adverse irritation to human skin, which has potential safety hazards. In addition, sodium is highly corrosive to the crucible, resulting in a short service life of the crucible, which further increases production costs. [0003] It can be seen that the prior art needs to be improved and enhanced. Contents of the invention [0004] In view of the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a method ...
