Embodiment l

[0017] Embodiment 1: Weigh 40 kilograms of A00 aluminum ingots and 60 kilograms of electrolytic manganese sheets; use an intermediate frequency furnace to heat the electrolytic manganese sheets to 1300-1400 o C to melt it completely; then add the aluminum ingot into the manganese melt, and stir evenly after the aluminum ingot is completely melted to form a uniform aluminum-manganese melt; then use a single-roll casting machine to cast a 1mm thick plate, and then Mechanically broken into flakes, this yielded about 100 kg of Al-60Mn master alloy.

Embodiment 2

[0018] Embodiment 2: Weigh 50 kilograms of A00 aluminum ingots and 50 kilograms of electrolytic manganese sheets; use an intermediate frequency furnace to heat the electrolytic manganese sheets to 1300-1400 o C to melt it completely; then add the aluminum ingots into the manganese melt, and stir evenly after the aluminum ingots are completely melted to form a uniform aluminum-manganese melt; Mechanically broken into flakes, this yielded about 100 kg of Al-50Mn master alloy.

Abstract

The invention relates to an aluminum-manganese intermediate alloy and a manufacturing method of the aluminum-manganese intermediate alloy, in particular to the aluminum-manganese intermediate alloy for adding manganese elements in an aluminum alloy casting process and the manufacturing method of the aluminum-manganese intermediate alloy. The aluminum-manganese intermediate alloy comprises, by weight, 30 to 60 % of aluminum, with a preference to 40 to 50 %; and 40 to 70 % of the manganese, with a preference to 50 to 60 %. The aluminum-manganese intermediate alloy has comparative high manganese content. By the adoption of the technology, alloy elements can be rapidly dissolved in molten aluminum and the production efficiency is improved, and therefore the use amount of the intermediate alloy can be reduced. The storage and transportation cost of the intermediate alloy can be reduced and the market competitiveness of the intermediate alloy is improved.

Description

technical field [0001] The invention relates to an aluminum-manganese intermediate alloy and a preparation method thereof, which is an aluminum-manganese intermediate alloy used for adding manganese element in the casting process of aluminum alloy and a preparation method of the aluminum-manganese intermediate alloy. Background technique [0002] In the preparation process of various alloys, it is often necessary to add a small amount of alloying elements to achieve the required chemical composition. For example, in the production process of 3000 series aluminum alloy, manganese element needs to be added. This alloying element can be added through Al-Mn master alloys or alloying additives. [0003] The so-called aluminum-manganese intermediate alloy is an intermediate transition alloy used to adjust the alloy composition in the production of aluminum alloy casting, which is composed of aluminum and manganese. In the existing aluminum-manganese master alloy, the content of ...
