Abstract
A kind of aluminium alloy innocuous refining flux, it is characterised in that：It is into being grouped as by following weight percents：Hexafluoro sodium aluminate 20 25%, graphite powder 5 10%, silica 1 3%, aluminium oxide 1 3%, sodium chloride 5 10%, sodium nitrate 20 25%, potassium fluosilicate 15 20%, anhydrous nitric acid calcium 1 5%.Preparation method is：It by above-mentioned each component in proportion with postponing, is crushed using pulverizer, and add in suitable quantity of water, is mixed uniformly, press is recycled to be pressed into bulk, finally carries out baking drying.The invention has the advantages that：It avoids that iron content in molten aluminium alloy is exceeded nontoxic, and easy to use, method is simple, at low cost, handling ease, reaches better de-ferrous effect.
Description
Technical field
The present invention relates to refining agent technical fields, and in particular to a kind of aluminium alloy innocuous refining flux.
Background technology
Aluminium and aluminium alloy are that current applications are very extensive, one of most economical applicable material, and the density of aluminium is smaller, though hardness
It is low, but various aluminium alloys are can be made into, such as duralumin, superduralumin, rustproof aluminum alloy, cast aluminium.These aluminium alloys are widely used in aircraft, vapour
The process industries such as vehicle, train, ship.In addition, cosmic rocket, space shuttle, artificial satellite are also closed using a large amount of aluminium and its aluminium
Gold, the electric conductivity of aluminium are only second to silver, copper and gold, have extensively in electric appliance process industry, electric wire industry and radio industry
Purposes, aluminium be heat good conductor, can industrially be constructed of aluminum various heat exchangers, heat sink material and cooker etc..Aluminium has preferably
Ductility (its ductility is only second to Jin Heyin), be widely used in packaging cigarette, candy etc., may also be fabricated which aluminium wire, aluminum strip, and
Various aluminum products can be rolled.The surface of aluminium is not easily susceptible to corrode, is often used to manufacture chemistry because there is fine and close oxide film
Reactor, medical instrument, refrigerating plant, petroleum refining device, oil and natural gas pipeline etc., and in the preparation process of aluminium,
It needs to refine aluminium, its purpose is to remove the field trash in aluminium, to improve the purity of aluminium, but at present for the essence of aluminium
Refining, usually due to the side effect of refining agent, can generate associated toxic substance.
Invention content
The technical problems to be solved by the invention be to provide it is a kind of so that refining product it is nontoxic, reach reduce pollution mesh
Aluminium alloy innocuous refining flux.
In order to solve the above technical problems, technical solution provided by the invention is：A kind of aluminium alloy innocuous refining flux, feature
It is：It is into being grouped as by following weight percents：Hexafluoro sodium aluminate 20-25%, graphite powder 5-10%, silica 1-
3%, aluminium oxide 1-3%, sodium chloride 5-10%, sodium nitrate 20-25%, potassium fluosilicate 15-20%, anhydrous nitric acid calcium 1-5%.
Preferably, it is into being grouped as by following weight percents：It is into being grouped as by following weight percents：Hexafluoro
Sodium aluminate 22%, graphite powder 8%, silica 2%, aluminium oxide 2%, sodium chloride 8%, sodium nitrate 22%, potassium fluosilicate 18%,
Anhydrous nitric acid calcium 3%.
Preparation method is：It by above-mentioned each component in proportion with postponing, is crushed, and is added in appropriate using pulverizer
Water is mixed uniformly, press is recycled to be pressed into bulk, finally carries out baking drying.
The invention has the advantages that：Avoid iron content in molten aluminium alloy exceeded nontoxic, easy to use, method letter
Single, at low cost, handling ease reaches better de-ferrous effect.
