Description
（One）Technical field
The present invention relates to aluminium intermediate alloy refining art, more particularly to a kind of Al-Ti-B alloy refining special-purpose high temperature slag former.
（Two）Background technology
Existing Al-Ti-B alloy production technology is mainly using the production of villiaumite method, mainly by potassium fluoborate and potassium fluotitanate
Mixture is added in 750~850 DEG C of aluminium body, makes Ti, B element be reduced out from villiaumite compound, in course of reaction
Substantial amounts of liquid slag is produced, its density ratio aluminium liquid is small, floats over aluminium liquid upper strata, and mobility is fabulous, is easy to be poured out from aluminium liquid,
But because it and aluminium have fabulous wetability, clean and its difficulty is removed, and it is general by temperature during Al-Ti-B alloy refining
Degree is controlled at 800~880 DEG C, beyond the temperature in use of common slag former.
（Three）The content of the invention
Defect in order to compensate for common slag former of the invention, there is provided a kind of low cost, efficiency high, the aluminium titanium boron of steady quality
Alloy refines the preparation technology of special-purpose high temperature slag former.
The present invention is achieved through the following technical solutions：
A kind of Al-Ti-B alloy refines special-purpose high temperature slag former, it is characterized in that, the weight part ratio of its constituent is：

22~27 parts of NaF；
Na3AlF616~25 parts；
CaF220~28 parts；
Na2SiF612~15 parts；
Above-mentioned raw materials addition mixer is stirred；By the material for stirring be heated in heating furnace 100~300 DEG C it
Between, insulation, until the moisture fully in removal slag former so that moisture≤0.5% in slag former；Obtain final product required slag making
Agent.
Preferred scheme is that the weight part ratio of each constituent is：
MgF215 parts；
25 parts of NaF；
Na3AlF620 parts；
CaF225 parts；
