Abstract

The invention discloses a high silicon-aluminum alloy efficient modifier. The high silicon-aluminum alloy efficient modifier comprises the following components in percentage by weight according to a formula: 4-5% of Na2CO3, 17-22% of Na2SO4, 3-5% of NaNO3, 35-42% of NaCl, 23-29% of KCl and 3-8% of NaF. The high silicon-aluminum alloy efficient modifier has the beneficial effects that the high silicon-aluminum alloy efficient modifier has excellent aluminium alloy modification effect and is capable of improving the quality of castings, refining crystal grains and obviously reducing the pinhole degree of the castings.

Description

The efficient alterant of a kind of silumin
Technical field
The present invention relates to the efficient alterant of a kind of silumin, belong to metallurgical technology field.
Background technology
The important means of the performance being raising aluminium alloy that goes bad, changed the crystallization of aluminium alloy by alterant, refinement particle, significantly improves the performance of aluminium alloy.At present with solid solution aluminium alloys such as Al-Cu system, Al-Mg system, Al-Zn systems when room temperature and high temperature, mechanical property all shows very remarkably, thus applies widely.But the disadvantage of above-mentioned alloy is macro crystallization coarse grains, and casting crack the most easily occurs, cause it can not give full play to the advantage of mechanical property, so be necessary to carry out Metamorphism treatment to the alloy of these series, make the grain refining of sosoloid.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides the efficient alterant of a kind of silumin.
To achieve these goals, technical scheme of the present invention is: the efficient alterant of a kind of silumin, and the component formula weight ratio of described alterant is: Na 2cO 34 ~ 5%, Na 2sO 417 ~ 22%, NaNO 33 ~ 5%, NaCl 35 ~ 42%, KCl 23 ~ 29%, NaF 3 ~ 8%.
Further, as a kind of preferred embodiment, the component formula weight ratio of described alterant is: Na 2cO 35%, Na 2sO 420%, NaNO 34%, NaCl 40%, KCl 25%, NaF 6%.
The invention has the beneficial effects as follows: for Aluminum alloy modification excellent, promote casting quality, this alterant can crystal grain thinning, significantly reduction foundry goods pinhole rate.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
