Abstract

The invention relates to a preparing method of an AlMo intermediate alloy. The AlMo intermediate alloy contains aluminum and molybdenum, and is specifically prepared from the following components in percentage by mass: 10-25% of Mo, less than or equal to 0.5% of Fe and the balance of aluminum and inevitable impurity elements According to the preparing method of the AlMo intermediate alloy, industrial pure metal molybdenum rods are adopted by the AlMo intermediate alloy in a line frequency furnace or a high-frequency furnace for batch and production. The product has high purity, good uniformity, and high efficiency and low cost industrializable batch production, the quality of the AlMo intermediate alloy is better than the quality of an intermediate alloy produced by using MoO3 as raw materials, the melting point of the product is low, and the AlMo intermediate alloy can be used for the addition use of light metal alloys such as aluminum alloys.

Description

technical field [0001] The invention relates to a method for preparing an AlMo master alloy, and belongs to the technical field of non-ferrous metal materials and their processing. Background technique [0002] At present, AlMo or AlMoTi master alloys are mostly used in aerospace and other fields, and the application range is narrow, and they have not yet been developed in the civil field, and the production cost is high. MoO3 and other fluorine salts are used as raw materials for production, and vacuum melting equipment is often used. For example, a kind of AlMo master alloy and its preparation method are disclosed in the patent CN102534315B. MoO3, CaF, etc. are used as raw materials. In the patent CN101476075A, Al powder, MoO3, CaF is used as raw material to prepare AlTiMo master alloy. [0003] With the extensive use of aluminum alloys in recent years, the scope of application has continued to expand, and some new additives such as modifiers and inoculants have been disc...
