Abstract
The present invention relates to P-Si intermediate alloy which is used for refining initial crystalline silicon in Al-Si alloy and Mg2Si in Mg-Si alloy and a preparation method thereof. The chemical composition (wt%) of the intermediate alloy includes 40.0 to 70.0 of silicon, 8.0 to 25.0 of phosphorus and at least one of nickel and manganese as the rest. The preparation method comprises the steps that pure silicon and at least one alloy raw material of pure nickel or pure manganese are melted in a high temperature smelting furnace; red phosphorus is heated to be at the temperature of 450 DEG C to 520 DEG C in a low temperature holding furnace protected by argon gas or nitrogen gas; phosphorus steam is communicated with the bottom of the silicon alloy melted body through a phosphorus conveying pipe, and the melted body is stirred to cause the phosphorus to be dissolved in the melted body; the melt body is directly cast into an ingot or atomized into powders. The intermediate alloy has the advantages of low-density, low melting point, good refining effect in use, etc.
Description
Technical field
The invention belongs to metal material field, particularly relate to a kind of Mg in refinement Al-Si alloy primary silicon and the Mg-Si alloy that is used for
2P-Si master alloy of Si and preparation method thereof.
Background technology
The method that general employing adds phosphorus in the industrial production is come the primary silicon (also claiming rotten the processing) in the refinement Al-Si alloy, mainly is with red phosphorus, microcosmic salt or phosphorus-forms such as copper master alloy adding.But these methods all exist many shortcomings: the burning-point of red phosphorus low (240 ℃) discharges a large amount of deleterious P during rotten the processing
2O
5Gas, serious environment pollution; Also there is problem of environmental pollution in microcosmic salt modification effect instability in the use; Phosphorus-copper master alloy density is big, fusing point is high, is leaving standstill under the stove melting condition, joins the easy precipitation in back, infusibilityization in the aluminium alloy melt, the modification effect instability, and make copper content increase in the alloy.The patent No. is that the Chinese patent of ZL 01 1 07704.2 has been reported Al-P-Cu master alloy and preparation method thereof, but phosphorus content is lower, is 2-6%, and add-on is bigger in use, is 0.6-1.0%, and use cost is higher.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of phosphorus content height, P-Si master alloy that density is little and preparation method thereof are provided.
The present invention realizes in the following manner:
A kind of P-Si master alloy comprises silicon, phosphoric, it is characterized in that it also contains at least a in nickel, the manganese element, and the mass percent of each component is: silicon 40.0-70.0%, and phosphorus 8.0-25.0%, surplus is at least a in nickel, the manganese.
The preparation method of above-mentioned P-Si master alloy is characterized in that may further comprise the steps:
(1) take by weighing raw material by mass percentage, pure silicon 40.0-70.0%, red phosphorus 8.0-25.0%, surplus be at least a in pure nickel and the pure manganese;
(2) in high temperature melting furnace with at least a alloying in pure silicon and pure nickel, the pure manganese, stir and in 1450～1550 ℃ of scopes, be incubated;
(3) in the low temperature holding furnace of argon gas or nitrogen protection, red phosphorus is heated to 450-520 ℃, keep phosphorous vapor pressure 1.0-1.5 normal atmosphere in the stove, by phosphorus transporting pipe phosphorous vapor is communicated to silicon alloy melt bottom in the step (2), and stirs alloy melt, impel phosphorus to be dissolved in this melt;
(4) casting ingot-forming or powder by atomization.
The P-Si master alloy has the little (3.6g/cm of density
3About) and the advantage of phosphorus content height (can reach 25%), and Si is the main alloy element in the Al-Si alloy, adopts the P-Si master alloy will make the composition adjustment simplification of alloy to its processing of go bad.In addition, the Mg-Si alloy is because Mg
2Si is mutually thick almost not to have use value, adopts P-Si master alloy refinement Mg effectively
2The Si phase, thus increase substantially the mechanics and the use properties of this material.Adding under 0.2% the situation, can make primary silicon size in the Al-20%Si alloy by refineing to below the 30 μ m more than the 150 μ m.Be a kind of new and effective Al-Si alloy and Mg-Si alloy inoculant, adopt this alterant to reduce production costs greatly.
