Abstract
The invention discloses a kind of aluminum refining agents, which is characterized in that includes the raw material of following proportion by weight：KCl20~30 part, NaCl30~50 part, CaF210~20 parts, Na2CO330~60 parts, Na2SO410~30 parts, Na3AlF62~20 parts, C2Cl65~10 parts, beneficial effects of the present invention：The slag inclusion in molten aluminum can be effectively removed, molten aluminum hydrogen content can be reduced, it is apparent to the clean-up effect of molten aluminum, deaeration capability is stronger, dosage is few, it does not chemically react with metal and furnace lining, control heating effect, reduce iron loss, reduce alumina burn out rate, reduce aluminium slag output capacity, the microstructure compactness of aluminium alloy round cast ingot after melting is uniform, substantially without loose, the defects of slag inclusion, increase the uniformity of the interior tissue of aluminium alloy round cast ingot and the refinement of crystal grain, improve the quality and processing performance of rear process aluminium extruded alloy profile, improve aluminium alloy round cast ingot yield rate.
Description
Technical field
The present invention relates to technical field of chemical paint, in particular to a kind of aluminum refining agents.
Background technology
Aluminium and its alloy show the characteristic for being easy to aoxidize, absorb gas in melting, casting cycle so that in molten aluminum
Gas and field trash are easily formed, it is a series of so as to cause the stomata of casting, shrinkage cavity and porosity, crackle, poured short and leakage etc.
Defect greatly reduces the performances such as the intensity of material, plasticity, fatigue resistance, anti-corrosion or even casting is caused to scrap, enables aluminum alloy to
Application be very restricted, therefore improve aluminium alloy degree of purity have very important significance, the work in relation to cleaning molten
Skill is also to ensure the key technology of aluminum alloy materials metallurgical quality, it has also become countries in the world are metallurgical, founding researcher extremely pays close attention to
Subject.
Invention content
The invention solves the above problems existing for background technology, provide a kind of aluminum refining agent.
In order to solve the above technical problems, the present invention provides a kind of aluminum refining agents, which is characterized in that including following matter
Measure the raw material of part proportioning：KCl20~30 part, NaCl30~50 part, CaF210~20 parts, Na2CO330~60 parts, Na2SO4 10
~30 parts, Na3AlF62~20 parts, C2Cl65~10 parts.
Preferably, a kind of aluminum refining agent, which is characterized in that include the raw material of following proportion by weight：
KCl22~28 part, 12~18 parts of 35~45 parts of NaCl, CaF2,15~25 parts of 40~50 parts of Na2CO3, Na2SO4,
6~9 parts of 4~16 parts of Na3AlF6, C2Cl6.
Preferably, a kind of aluminum refining agent, which is characterized in that include the raw material of following proportion by weight：
KCl23~27 part, 13~17 parts of 38~42 parts of NaCl, CaF2,18~22 parts of 42~48 parts of Na2CO3, Na2SO4,
7~8 parts of 8~12 parts of Na3AlF6, C2Cl6.
Beneficial effects of the present invention：Aluminum refining agent of the present invention can effectively remove the slag inclusion in molten aluminum, can
Apparent to the clean-up effect of molten aluminum to reduce molten aluminum hydrogen content, deaeration capability is stronger, and dosage is few, does not rise and changes with metal and furnace lining
Act on, and controls heating effect, reduces iron loss, reduces alumina burn out rate, reduces aluminium slag output capacity, the aluminium after melting
The microstructure compactness of alloy circle ingot casting is uniform, substantially without loose, slag inclusion the defects of, increase the inside of aluminium alloy round cast ingot
The uniformity of tissue and the refinement of crystal grain improve the quality and processing performance of rear process aluminium extruded alloy profile, improve aluminium alloy
Circle ingot casting yield rate.
