Aluminum-titanium-boron alloy produced by virtue of multi-frequency induction furnace and production process of alloy

Abstract

The invention discloses an aluminum-titanium-boron alloy produced by virtue of a multi-frequency induction furnace and a production process of the alloy. The aluminum-titanium-boron alloy produced by virtue of the multi-frequency induction furnace consists of the following raw materials: an aluminum ingot, potassium fluotitanate, potassium fluoborate, a diluting buffer, a refining agent and a slag absorbing agent, wherein the slag absorbing agent includes raw materials of sodium chloride, potassium chloride, sodium fluorosilicate and calcium fluoride. The invention provides an important method for producing a high-quality aluminum-titanium-boron series intermediate alloy, and the aluminum-titanium-boron alloy is produced by virtue of the multi-frequency induction furnace; before charging, molten aluminum is refined and is added with a fluoride salt mixture which serves as a heterogeneous nucleation agent in late-phase reaction, so that titanium and boron particle compound generated from the late-phase reaction is more uniform in distribution; by adding the diluting buffer to the fluoride salt mixture, reaction speed is effectively controlled and a separation and purification effect on fluoride salt slag and alloy is enhanced; and upon inspection and analysis, in the product produced by the invention, the titanium and boron particle compound is small, uniform in distribution and low in slag content.

Description

technical field [0001] The invention relates to a production process of an aluminum-titanium-boron alloy, in particular to an aluminum-titanium-boron alloy produced by a multi-frequency induction furnace and a production process thereof. Background technique [0002] At present, there are many theoretical studies on the preparation of aluminum-titanium-boron master alloys. According to the properties of raw materials, they can be divided into oxide method, fluoride salt method and pure titanium particle method, etc.; according to the preparation process, they can be divided into aluminothermic reduction method, electrolysis method, Spread high-temperature synthesis, etc. However, at present, the fluorine salt method is widely used in the production of high-quality aluminum-titanium-boron master alloys in the industry, that is, the aluminum-titanium-boron alloy is produced by using K2TiF6 and KBF4 through the aluminothermic reaction.

[0003] 2) The disadvantage of the fluorine salt method is that it is difficult to effectively and completely remove the inclusions brought in by the by-product potassium fluoroaluminate during the alloying process and the corrosion of the molten salt on the refractory material.

Therefore, the aluminum-titanium-boron alloy produced by the common method cannot meet the growing and constantly innovative requirements for the refinement of high-precision, high-quality aluminum alloy materials.
