Abstract
The invention discloses a kind of silico-aluminum refining deterioration agents, including：The silicon of 10-15 mass %, the alundum (Al2O3) of 20-30 mass %, the sodium chloride of 20-30 mass %, the potassium chloride of 10-15 mass %, the hexafluoro sodium aluminate of 10-20 mass %, the sodium phosphate of 5-10 mass %, the sodium thiosulfate of 3-5 mass %, the calcium carbonate of 3-8 mass %, the phenyl-hexafluoride of 1-3 mass %, 10-20 mass % carbon trichloride and 3-8 mass % yttrium.Refining deterioration agent using the present invention carries out preparing silico-aluminum, and primary silicon can be refined in silico-aluminum, to improve the mechanical property of silico-aluminum.
Description
Technical field
The present invention relates to a kind of silico-aluminum refining deterioration agents.
Background technology
Refining deterioration agent is that one kind is added in alloy molten press casting procedure, to improve the chemical reagent of alloy property.
Chinese patent CN102226239A discloses a kind of aluminum or aluminum alloy cleaning molten processing refining flux and its system
Preparation Method, by mass percentage, the refining agent composition of raw materials are the powder mixtures being made of following components：NaCl 25-
35%, KCl 25-35%, Na3AlF6 and/or K3AlF6 15-25%, Na2SO4 and/or K2SO4 4- 10%, CaCO3 and/
Or Na2CO3 3-10%, REF3 and/or RECl 3-6%；Wherein, the mass ratio of NaCl and KCl is 1: 1；RE is Ce or La.It should
The refining agent of invention can fully be spread after entering melt, not adsorb reunion, not plug-hole；With dry slag ability is efficiently made, do not glue
Stagnant aluminum melt；Even if flux has minor response, reaction product that can together be removed with clinker with aluminum melt；With higher degasification,
Remove the gred efficiency.
Chinese patent CN104561632A discloses a kind of alloy refining alterant, and ingredient and its proportioning are：Chlorination
20-25 parts of potassium, 30-35 parts of sodium chloride, 3-5 parts of sodium carbonate, 3-6 parts of calcirm-fluoride, 10-15 parts of sodium sulphate, 20-25 parts of potassium nitrate,
5-10 parts of phenyl-hexafluoride, 1-2 parts of rare earth.The aluminum refining agent of the invention can effectively remove the slag inclusion in molten aluminum, while can be with
Molten aluminum hydrogen content is reduced, it is apparent to the clean-up effect of molten aluminum.
However, when silicone content is excessively high in silico-aluminum, sodium salt, sylvite can only effective refining eutectic silicon, and primary silicon is then
It is unable to get effective refinement, causes alloy there are certain defects, excessive primary silicon can cause alloy mechanical property to decline.
Invention content
The object of the present invention is to provide a kind of silico-aluminum refining deterioration agent, primary silicon can obtain carefully in silico-aluminum
Change, to improve the mechanical property of silico-aluminum.
To achieve the goals above, the present invention provides a kind of silico-aluminum refining deterioration agent, the formula of the refining deterioration agent
Including：The silicon of 10-15 mass %, the alundum (Al2O3) of 20-30 mass %, sodium chloride, the 10-15 mass % of 20-30 mass %
Potassium chloride, the hexafluoro sodium aluminate of 10-20 mass %, the sodium phosphate of 5-10 mass %, 3-5 mass % sodium thiosulfate, 3-8
The calcium carbonate of quality %, the phenyl-hexafluoride of 1-3 mass %, 10-20 mass % carbon trichloride and 3-8 mass % yttrium.
Contain rare earth and P elements in the refining deterioration agent of the present invention, rare earth and P elements are in relatively high excessively total of silicon content
Coarse primary silicon can be effectively refined and disperseed in crystal silicon aluminium alloy, and primary silicon is made to become tiny spherical by original strip
And rod-short.Since primary silicon coarse in transcocrystallized Al-Si alloy can seriously damage the mechanical property of silico-aluminum,
The refinement of primary silicon can be such that the crystal grain distribution of silico-aluminum is more uniformly distributed, to improve the mechanical property of silico-aluminum.
Specific implementation mode
It is described in detail below in conjunction with specific implementation mode.It should be understood that specific embodiment party described herein
Formula is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention provides a kind of silico-aluminum refining deterioration agent, and the formula of the refining deterioration agent includes：10-15 mass %'s
Silicon, the alundum (Al2O3) of 20-30 mass %, the sodium chloride of 20-30 mass %, the potassium chloride of 10-15 mass %, 10-20 matter
Measure the hexafluoro sodium aluminate of %, the sodium phosphate of 5-10 mass %, the sodium thiosulfate of 3-5 mass %, 3-8 mass % calcium carbonate,
The yttrium of the phenyl-hexafluoride of 1-3 mass %, the carbon trichloride and 3-8 mass % of 10-20 mass %.
Contain rare earth and P elements in the refining deterioration agent of the present invention, rare earth and P elements are in relatively high excessively total of silicon content
Coarse primary silicon can be effectively refined and disperseed in crystal silicon aluminium alloy, and primary silicon is made to become tiny spherical by original strip
And rod-short.Since primary silicon coarse in transcocrystallized Al-Si alloy can seriously damage the mechanical property of silico-aluminum,
The refinement of primary silicon can be such that the crystal grain distribution of silico-aluminum is more uniformly distributed, to improve the mechanical property of silico-aluminum.
