Abstract

The invention discloses an aluminum-manganese (AlMn10) master alloy which is composed of mother batches and accessories. The mother batches include primary aluminum liquid and a first-grade electrolytic manganese flake; the accessories include a refining agent and a covering agent. The invention is characterized in that the alloy composition is as follows according to the weight percentage: 99.7-99.9% of manganese content in the first-grade electrolytic manganese flake, 0.01-0.1% of silicon content in the primary aluminum liquid, 0.01-0.12% of iron content and 99.97-99.99% of aluminum content. The input amounts of the alloy and the primary aluminum liquid (calculating by 10 T furnace) is 8-9T of the primary aluminum liquid, 1-2T of the electrolytic manganese flake and right amounts of the refining agent and covering agent. The master alloy has the advantage that the aluminum-manganese (AlMn10) master alloy achieves the purpose of energy-saving and environment protection by the method of using the primary aluminum liquid to produce the aluminum-manganese master alloy, thereby greatly lowering the investment cost and processing cost, shortening the production period and simplifying the manufacturing technique.

Description

technical field [0001] The present invention relates to a kind of aluminum manganese (AlMn 10 ) master alloy, especially an aluminum-manganese (AlMn 10 ) master alloy and a preparation method thereof, belonging to the technical field of nonferrous metals. Background technique [0002] At present, my country's AlMn 10 The master alloy is completed by melting and remelting aluminum ingots. Due to the complicated process and long production and processing cycle, the processing cost is relatively high. In order to reduce energy consumption, reduce investment and shorten production cycle. We used the primary aluminum liquid to AlMn 10 Master alloys were tested for production. After more than half a year of hard work, good results have been achieved. A qualified AlMn 10 The master alloy came into being. Contents of the invention [0003] The purpose of the invention is to overcome the shortcoming of prior art, provide a kind of aluminum manganese (AlMn 10 ) master alloy ...
