Abstract

The invention discloses Al-Ti-B master alloy and a preparation method thereof, wherein the Al-Ti-B master alloy is prepared by main materials and auxiliary materials, the main materials are a primary aluminum liquid, potassium fluotitanate and potassium fluoborate, and the auxiliary materials are a refining agent, a covering agent and remelted aluminum ingots. The Al-Ti-B master alloy is characterized in that the alloy consists of the following ingredients in percentage by weight: 97 to 99 percent of potassium fluotitanate, and 97 to 99 percent of potassium fluoborate, wherein the content of titanium is 17 to 19 percent, and the content of boron is between 6 and 8 percent; and in the primary aluminum liquid, the content of silicon of is between 0.01 and 0.1 percent, the content of iron is between 0.001 and 0.12 percent, and the content of aluminum is between 99.97 and 99.99 percent. The adding amount of alloy and the primary aluminum liquid (calculated as a 10T furnace) is 8 to 9T of the primary aluminum liquid, 1 to 1.5T of potassium fluotitanate, 1 to 1.5T of potassium fluoborate, and a proper amount of refining agent and covering agent. The master alloy and the preparation method have the advantages that the preparation method greatly reduces investment cost, shortens production period, simplifies production technology, reduces processing cost, and achieves the aims of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to an aluminum-titanium-boron master alloy, in particular to an aluminum-titanium-boron master alloy and a preparation method thereof, belonging to the technical field of nonferrous metals. Background technique [0002] At present, my country's aluminum titanium boron (AlTi 5 B 1 ) 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 aluminum titanium boron (AlTi 5 B 1 ) master alloy for production attempts. After more than half a year of hard work, good results have been achieved, and the qualified aluminum-titanium-boron master alloy has been successfully produced by using the original aluminum liquid. Contents of the invention [0003] The purpose of the present inventi...
