Abstract

The invention discloses an allumel intermediate alloy and a preparation method thereof. The alloy is made of main ingredients and minor ingredients, wherein the main ingredients are primary aluminum liquid and metallic nickel, and the minor ingredients are a refining agent and a covering agent. The characteristic thereof lies in the alloy composition according to weight percentage: 99.96%-99.98% of nickel in the metallic nickel; 0.01%-0.1% of silicon, 0.001%-0.12% of ferric, and 99.97%-99.99% of aluminum in the primary aluminum liquid. The input amount of the alloy and the primary aluminum liquid (counted by 10T furnace) is as follows: 8T-9T of primary aluminum liquid, 0.96T-1.2T of metallic nickel, and proper amount of the refining agent and the covering agent. The advantage thereof is that the allumel intermediate alloy is produced by the method of using primary aluminum liquid to achieve the aim of energy saving and environment protection, thus remarkably reducing investment cost, shortening production period, simplifying production technique and lowering process cost.

Description

technical field [0001] The invention relates to an aluminum-nickel master alloy, in particular to an aluminum-nickel master alloy and a preparation method thereof, belonging to the technical field of nonferrous metals. Background technique [0002] At present, my country's aluminum nickel (AlNi 10 ) 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 primary aluminum liquid pair (AlNi 10 ) intermediate alloy for production trial, and achieved good results, using the original aluminum liquid to produce qualified aluminum nickel (AlNi 10 ) master alloy came into being. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide an Al-Ni master alloy and its preparation metho...
