Abstract
The invention discloses a kind of high fluidity die casting kirsite, the weight percent of chemical component is aluminium 4.0-5.0%, copper 0.01-0.1%, magnesium 0.001-0.05%, titanium 0.001-1%, iron≤0.03%, lead≤0.003%, cadmium≤0.002%, remaining is zinc and inevitable impurity.The die casting is excellent with kirsite mobile performance, and manufacture easy to produce, is easily manipulated, and is able to satisfy high fluidity demand when manufacturing ultra-thin part, has ensured the die casting prepared.
Description
Technical field
The present invention relates to alloy manufacture field, in particular to a kind of high fluidity die casting kirsite.
Background technique
The essence of compression casting (abbreviation die casting) is to make liquid or semi-liquid metal with higher speed under high pressure effect
Fill die-casting die (die casting) type chamber, and form under stress and solidify and the method that obtains casting.With other casting methods
Compare, die casting has following three aspects advantage: 1. good product quality: casting dimension accuracy is high, and surface smoothness is good；Intensity and hardness
It is higher；Dimensionally stable, interchangeability are good；It can the thin-wall complicated casting of die casting.2. high production efficiency: machine productivity is high；Die-casting die
Service life is long, one pair of die-casting die, zinc die casting alloys, and the service life is up to hundreds of thousands time or even up to a million times；Easily realize mechanization and automatic
Change.3. economic effect is excellent: since pressur casting size is accurate, the advantages that table floodlight is clean.Generally no longer it is machined and straight
Use or processing capacity very little are connect, so not only improving metal utilization, but also reduces a large amount of process equipment and working hour；Casting
Price is easy；Combination die casting can be used with other metals or nonmetallic materials.Not only it had saved assembly man-hour but also had saved metal.Although
Die casting has many advantages, such as, but there is also some problems simultaneously, when cast temperature is lower or when making ultra-thin part,
The defects of mobile performance of existing national standard diecasting alloys is deteriorated, die casting crackle, high rejection rate obviously increases.It is existing in order to solve
The problem of diecasting alloys poor fluidity, develops a kind of novel high fluidity diecasting alloys, when cast temperature is lower or is making
When making ultra-thin die casting, yield rate is improved.
Summary of the invention
The object of the present invention is to provide a kind of poor mobile performances that can effectively overcome the problems, such as existing diecasting alloys, have stream
The zinc die casting alloys of dynamic property more excellent effect.To realize said effect, the present invention provides following solutions:
A kind of high fluidity die casting kirsite, including zinc further include by weight percentage aluminium 4.0-5.0%, copper
0.01-0.1%, magnesium 0.001-0.05%, titanium 0.001-1%, iron≤0.03%, lead≤0.003%, cadmium≤0.002%；
Further, by weight percentage, zinc 94-96%, aluminium 4.0-5.0%, copper 0.01-0.1%, magnesium 0.001-
0.03%, titanium 0.001-0.5%, iron≤0.03%, lead≤0.003%, cadmium≤0.002%, remaining is inevitable impurity.
Technical principle of the invention and beneficial technical effect: aluminium, copper, magnesium, the Ti content added in the technical program is pressed
Under amount ranges of the invention accurately control, form eutectic alloy, eutectic alloy fusing point is lower, can production when lower temperature
Under make wherein each component be completely melt that under identical cast temperature, eutectic composition alloy graining temperature is minimum, comparatively liquid
The degree of superheat (i.e. pouring temperature and alloy melting point temperature difference) of state alloy greatly, postpones the solidification of liquid alloy, therefore the stream of alloy
Dynamic property is good, and titanium elements have the function of refinement crystal grain in this programme, and having reached prevents from cracking after die casting is excessively thin
Defect occurs, to increase the mobile performance and casting yield of kirsite.Compared to current YZZnAl4A and
YZZnAl4Cu1 diecasting alloys, it is high by 20% or more in synthermal lower kirsite mobile performance of the invention, and lower temperature such as
At 450-470 DEG C, mobility highest can be improved 30% or more；Make 1.2mm or less thickness thin-section casting when, casting at
Product rate promotes 50% or more.
Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment, to this
Invention is further described.It should be understood that these descriptions are merely illustrative, and it is not intended to limit the scope of the invention.This
Outside, in the following description, descriptions of well-known structures and technologies are omitted, so as not to unnecessarily obscure the concept of the present invention.
The present invention is further illustrated With reference to embodiment
The alloy production process of this civilization are as follows: in line frequency coreless induction furnace, heating and electromagnetic stirring function are opened,
450-500 DEG C melts zinc, after zinc is completely melt, is proportionally added into aluminium, is warming up to 500-550 DEG C, in heating and electricity
Under magnetic stirring action, aluminium fusing in 10-30 minutes is finished, and industrial chlorinations are added in the ratio of 0.5-1.0 ‰ after aluminium fusing
Then ammonium slag making carries out slag hitting, after slag hitting then temperature control sequentially adds copper, magnesium, titanium at 500-550 DEG C in proportion,
Midfeather 1-2 minutes, electromagnetic agitation is carried out when being added, after 10-20 minutes, all metal moltens are stirred evenly, sampling point
Analysis carries out being cast into finished product packing shipping again after reaching the scope of the present invention.
The present invention provides a kind of high fluidity die casting kirsite, and the weight percent of chemical component is aluminium 4.0-
5.0%, copper 0.01-0.1%, magnesium 0.001-0.05%, titanium 0.001-1%, iron≤0.03%, lead≤0.003%, cadmium≤
0.002%, remaining is zinc and inevitable impurity.
Further, the weight percent of chemical component are as follows: aluminium 4.0-5.0%, copper 0.01-0.1%, magnesium 0.001-
0.03%, titanium 0.001-0.5%, iron≤0.03%, lead≤0.003%, cadmium≤0.002%, zinc surplus account for about 94-96%,
Remaining is inevitable impurity.
Alloy and YZZnAl4A, YZZnAl4Cu1 alloy carry out mobile performance test comparison through the invention, using self-control
Multiple U-shaped fluidity testing instrument is averaged after many tests at different temperatures, and test result is as follows shown in table, it is seen then that this
The alloy flowability of invention is excellent.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
