Aluminum zirconium middle alloy and preparation method thereof

Abstract

The invention discloses an aluminum zirconium middle alloy and a preparation method thereof; the aluminum zirconium middle alloy is made from main materials and auxiliary materials; the main materials are primary aluminum liquid and sponge zirconium powder; the auxiliary materials are refining agent and covering agent. The invention is characterized in that the alloy comprises the following components by weight: 99 percent to 99.9 percent of zirconium in the sponge zirconium powder; 0.01 percent to 0.1 percent of silicon, 0.01 percent to 0.12 percent of iron and 99.97 percent to 99.99 percent of aluminum in the primary aluminum liquid. The using amount of the alloy and the primary aluminum liquid (calculated according to a 10T furnace) is as follows: 8T to 9T of primary aluminum liquid, 0.39T to 0.5T of sponge zirconium powder, and appropriate amount of refining agent and covering agent. The invention has the advantage of achieving the purpose of energy conservation and environmental protection by using the method of producing aluminum zirconium middle alloy by the primary aluminum liquid, thereby greatly lowering the investment cost, shortening the production period, simplifying the production process, and reducing the processing cost.

Description

technical field [0001] The invention relates to an aluminum-zirconium master alloy and a preparation method thereof, belonging to the technical field of nonferrous metals. Background technique [0002] At present, my country's aluminum zirconium (AlZr 4 ) The master alloy is completed by melting and remelting aluminum ingots. Due to the complex 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 original aluminum liquid to try to produce aluminum-zirconium master alloy. After more than half a year of hard work, good results have been achieved, and an aluminum-zirconium-aluminum-zirconium master alloy has emerged as the times require. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an aluminum-zirconium master alloy and its preparation method. The alumi...
