Abstract
The invention discloses a compound modified zinc alloy, which is prepared by adding a rare earth and nickel-titanium compound modifier in a conventional die-cast zinc alloy production process and smelting. The compound modified zinc alloy comprises the following components in percentage by weight: 3.9-4.0% of aluminum, 0.03-0.04% of magnesium, less than 0.07% of impurity ingredients containing lead, iron, cadmium, tin and the like and the balance of zinc; and the compound modifier is a complex of rare earth metal and a nickel-titanium additive and accounts for 0.00020-0.0050% by weight. The modified zinc alloy disclosed by the invention has the advantages of excellent mechanical property and machining performance, low melting point temperature, good corrosion resistance, difficulty in cracking and deformation, high surface smoothness of a die-cast piece, extremely excellent balance between physical property and mechanical property and excellent castability, and is suitable for various die-cast pieces.
Description
Technical field
The present invention relates to a kind of manufacturing zinc alloy product, belong to the melting technology field of alloy product.
Background technology
Because it is corrosion-resistant that zinc alloy has in atmosphere, maimed material is convenient to recovery and remelting etc., is widely used in making various products.High aluminium zinc alloy is rising a kind of novel casting alloy, and its intensity is high, but plasticity, toughness are relatively poor, if can further improve its mechanical property, will improve work reliability, the broadened application scope.For improving the as cast condition plasticity and toughness of high aluminium zinc alloy, people often adopt the REE processing of going bad, with crystal grain thinning and increase substantially its plasticity and toughness.On the other hand, in the melting of zinc alloy, often add element additives such as nickel agent, titanium agent and promote melting, but use rare earth alterative and NiTi additive simultaneously, and obtain the fine zinc alloy product, also rarely seen successful story.
Summary of the invention
The object of the present invention is to provide a kind of composite inoculating zinc alloy,, make zinc alloy product have excellent mechanical property, corrosion resistance nature, enlarge the product application scope through compound interpolation rare earth alterative and NiTi additive.
The technical scheme that the present invention realizes is following: a kind of composite inoculating zinc alloy; It is in the MAZAK production process of routine, to add rare earth and the melting of NiTi compound modifier forms; The shared weight percent of each component of composite inoculating zinc alloy is: aluminium 3.9%～4.3%, magnesium 0.03%～0.04%; Comprise lead, iron, cadmium, tin etc. at interior impurity component less than 0.07%, surplus is a zinc; The shared weight percent of compound modifier is: 0.00020～0.0050%.
Described compound modifier is meant the complex body of rare earth metal and NiTi element additive; Described rare earth metal is meant lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, the single metal of yttrium; Add it and can make the alloy casting state structure refinement, improve the comprehensive mechanical property of alloy.
Described NiTi element additive is meant the mixture of nickel agent and titanium agent, and adding it can effectively can avoid melt overheat, shortens the melting refining time and reduces scaling loss.
The shared composite inoculating agent content of described NiTi element is titanium 1-5%, nickel 0.5-3%.
Add rare earth alterative, can significantly change the metallographic structure characteristic of MAZAK, optimize weave construction, crystal grain thinning is removed grain boundary impurity, suppresses the harmful effect of impurity element; Add the NiTi element additive, can effectively promote the melting of zinc alloy.Adopt the rare earth alterative and the NiTi element additive of suitable proportioning to constitute compound modifier, the significantly lifting that brings the zinc alloy product performance.Through adding the NiTi element additive, can accurately control the content of various metals in the zinc alloy, the metal casting yield can effectively be avoided melt overheat up to 95%, shortens the melting refining time and reduces scaling loss.Advantages such as therefore, the zinc alloy additive has easy to use, and batching is accurate and economical and practical.Under identical die casting condition, the composite inoculating zinc alloy is compared with not rotten zinc alloy, and tensile strength, unit elongation improve more than 10%, and hardness, corrosion resistance nature obviously improve.
The present invention compared with prior art has excellent mechanical property and machinability, and temperature of fusion is low; Corrosion resistance and good, not easy to crack and distortion, die casting surfacing; Advantages such as highly polished and long service life have splendid balance on its physics and the mechanical property, have good castibility; Be applicable to various die castings, can be widely used in the casting of devices such as toy, bathhouse article, household goods, reducing valve, electronics and electrical appliance.Abundant in view of China's rare earth resources, this invention has big realistic meaning undoubtedly.
Embodiment
Below list two kinds of main embodiments of the present invention: the one, international standard 3# zinc alloy is added compound modifier of the present invention, promote product performance; The 2nd, international standard 5# zinc alloy is added compound modifier of the present invention.Under two kinds of embodiments, the shared weight percent of each component of zinc alloy sees the following form:
Table one: the shared weight percent of each component of zinc alloy
For excellent properties of the present invention is described, the Mechanics Performance Testing and the anti-corrosion test result of product of the present invention and traditional product contrasted as follows:
Table two: Mechanics Performance Testing
Visible from last table, the composite inoculating zinc alloy is compared with not rotten zinc alloy, and tensile strength, unit elongation improve more than 10%, and hardness obviously improves;
Table three: anti-corrosion test
In the last table, A is not for adding the compound modifier zinc alloy, and B is the zinc alloy that has added compound modifier.Test conditions is 26 ℃ of room temperatures, 0.9917 standard atmospheric pressure, humidity 72% is not airtight.Visible from last table, the composite inoculating zinc alloy is compared with not rotten zinc alloy, and corrosion resistance nature obviously promotes.
Through adding the NiTi element additive, can accurately control the content of various metals in the zinc alloy in addition, the metal casting yield is up to 95%, and temperature of fusion is low, and 380
0Can throw the stove fusing more than the C, reduce the scaling loss of zinc liquid.Advantages such as therefore, the zinc alloy additive has easy to use, and batching is accurate and economical and practical.
Know that by above this composite inoculating zinc alloy behind adding rare earth and the NiTi compound modifier, can significantly improve correlated performance indexs such as tensile strength of alloys and erosion resistance, thereby be met the high-quality zinc alloy product that use properties requires.
