Abstract
The invention discloses a kind of aluminium and aluminium alloy solution refining slag-cleaning agent, the slag-cleaning agent each component, it is by mass percentage：Sodium fluoride 5-10%, cryolite 6-16%, potassium chloride 15-25%, potassium nitrate 1-5%, prodan 6-8%, carbon dust 5 10%, remaining adds sodium chloride to 100%.The use of the slag-cleaning agent will simplify aluminium and aluminium alloy smelting operation, can reduce the labor intensity of worker.Improve alloy mechanical intensity, enhancing weldability of metals, electric conductivity, the advantages of splendid scarfing cinder effect, will reduce operating process using the product, and reduce labor intensity, reduce melting cost, and increase yield rate.
Description
Technical field
The present invention relates to a kind of aluminium and aluminium alloy solution refining slag-cleaning agent, belong to aluminum alloy smelting field.
Background technology
Aluminium alloy is most widely used a kind of non-ferrous metal structural material in industry, in Aeronautics and Astronautics, automobile, machinery
Widely applied in manufacture, ship and chemical industry.Aluminium and aluminium alloy have one layer very thick floating after refining on aluminium liquid surface
Slag, there is more metallic aluminium in these slags, the effect of slag-cleaning agent is exactly to increase the surface tension on slag and aluminium interface, is there is agitation
In the case of, efficiently separated using rear aluminium liquid and slag, and slag is turned into dryness powdery slag, the aluminium effectively reduced in slag contains
Amount, the loss of aluminium is reduced when skimming, the aluminium slag separation being primarily adapted for use in aluminum-alloys furnace.Due to the impurity in aluminium alloy solution and
The presence of gas so that refining treatment is essential.The metallurgical quality that aluminium alloy is improved by refining seems extremely important, typically
Aluminum alloy smelting temperature does not reach the quality requirement of smelting at 700 DEG C -760 DEG C less than 700 DEG C of existing refining agents, and beats
The slag aluminum content gone out is higher, and the rate of recovery for enabling aluminum alloy to smelt reduces.
The content of the invention
The present invention is to solve the above problems, provide a kind of aluminium and aluminium alloy solution refining slag-cleaning agent, slag-cleaning agent each component,
It is by mass percentage：Sodium fluoride 5-10%, cryolite 6-16%, potassium chloride 15-25%, potassium nitrate 1-5%,
Prodan 6-8%, carbon dust 5-10%, remaining adds sodium chloride to 100%.
Further, described slag-cleaning agent each component, it is by mass percentage：Sodium fluoride 5%, cryolite 6%,
Potassium chloride 15%, potassium nitrate 1%, prodan 6%, carbon dust 10%, remaining adds sodium chloride to 100%.
Further, described slag-cleaning agent each component, it is by mass percentage：Sodium fluoride 10%, cryolite
16%, potassium chloride 25%, potassium nitrate 5%, prodan 8%, carbon dust 8%, remaining adds sodium chloride to 100%.
Further, described slag-cleaning agent each component, it is by mass percentage：Sodium fluoride 8%, cryolite
11%, potassium chloride 20%, potassium nitrate 3%, prodan 7%, carbon dust 8%, remaining adds sodium chloride to 100%.
The beneficial effects of the invention are as follows：The use of the slag-cleaning agent will simplify aluminium and aluminium alloy smelting operation, can reduce work
The labor intensity of people.Alloy mechanical intensity is improved, enhancing weldability of metals, electric conductivity, the advantages of splendid scarfing cinder effect, is used
The product will reduce operating process, and reduce labor intensity, reduce melting cost, increase yield rate.
