A Zn-Al-Mg-RE quaternary alloy zinc ingot is prepared with low cost rapidly and conveniently by adopting the preparation method, and the yields of Mg and RE elements are improved greatly.
Description
Technical field
The present invention relates to a kind of zinc ingot metal preparation method, relate in particular to a kind of quad alloy zinc ingot metal preparation method.
Background technology
All the time, iron and steel is generally applied in various fields as main structured material.Yet the fatal shortcoming of iron and steel is easily to produce corrosion in corrosive medium and lost efficacy.In order to improve the corrosion resisting property of steel part, plating one deck zinc, zn alloy coating in the steel part outside becomes the at present topmost method that prevents the steel matrix corrosion.The coating development experience several stages such as pure zinc coating, Zn-Al coating, Zn-Al-Mg coating.Data of literatures shows, containing the Mg corrosion resistance coating, is several times to more than 20 times of pure zinc coating.
Before zinc-plated, need to first prepare zinc ingot metal, preparing in advance zinc ingot metal has the benefit of two aspects: (1) is in actual industrial production, along with production is carried out, zinc constantly consumes in the zinc pond, form with zinc ingot metal is carried out supply to zinc and the alloying element consumed in the zinc pond, is conducive to enhance productivity; (2) be convenient to regulate zinc pond composition.
At present the alloy zinc ingot in science and technology research forward position is Zn-Al-Mg-RE quad alloy zinc ingot metal, but the Zn-Al-Mg-RE zinc ingot metal is difficult to preparation, this be because of:
The fusing point of (1) four kind of element differs larger, the fusing point of Al and Mg element is close, be respectively 660 ℃, 650 ℃, the fusing point of Zn is 420 ℃, the rare earth element fusing point, more than 800 ℃, therefore adds Mg element and rare earth element in zinc liquid, needs to improve the temperature of zinc liquid, because the saturation vapour pressure of zinc is lower, improve zinc liquid temperature and cause zinc liquid easily to evaporate;
(2) solid solubility of rare earth element in pure zinc is less, therefore add rear dissolving quite slow, the density ratio zinc liquid of rare earth is little in addition, float over zinc liquid surface after adding, form oxide compound, and the oxide compound fusing point is higher, solid solubility is less, therefore be difficult to directly in zinc liquid, add rare earth element, this is one of gordian technique of preparing of zinc ingot metal;
(3) Mg element and rare earth be in the easy spontaneous combustion of comparatively high temps, and to zinc ingot metal, preparation makes troubles and be dangerous for this, this be zinc ingot metal prepare gordian technique two.
In current Zn-Al-Mg-RE quad alloy preparation process, the main method addressed the above problem has:
For adding of Mg element: (1), according to the preparation method of Mg alloy, is increased to 700 ℃ of left and right to zinc liquid temperature, constantly to zinc liquid surface, passes into shielding gas, prevents that Mg from burning in preparation process.The shortcoming of this method is that temperature is high, troublesome poeration, cost is high, magnesiaization is serious, and the gas of its discharge has pollution to atmosphere; (2) add a certain amount of insulating covering agent in preparation process, prevent the Mg burning, yet, for zinc-plated industry, add insulating covering agent can bring impurity into, directly affect the quality of galvanized workpiece.
For adding of rare earth element: (1) puts into stainless steel box to rare earth, is pressed in zinc liquid, allows rare earth slowly melt; But this method can be brought the Fe element in zinc liquid into, has increased the impurity component of zinc ingot metal.(2) zinc liquid is watered on rare earth, wrap rare earth, yet put into zinc liquid, allow its slow fusing.The shortcoming of this method is that the zinc layer on rare earth surface dissolves in zinc liquid before rare earth dissolves not yet fully, therefore can not realize well adding rare earth element this purpose in zinc liquid.(3) elements such as Zn, Mg, RE are put into to vacuum induction furnace and carry out vacuum melting, the shortcoming of this method is that preparation trouble, cost are high, and does not meet the requirement of industrialized mass.
Summary of the invention
The purpose of this invention is to provide a kind of brand-new Zn-Al-Mg-RE (La, Ce or La and Ce mishmetal) zinc ingot metal preparation method, use present method, can be fast, simply, add Mg, RE element efficiently in zinc liquid, it is high that prepared zinc ingot metal has an Absorbing Alloy Element Rate, the advantage such as alloy ingredient good stability, preparation cost are low, be applicable to the galvanizing industrial production, be particularly suitable for continuous hot-dipping galvanizing.
The Zn-Al-Mg-RE zinc ingot metal prepares key step: at first prepare Zn-Al-RE (La, Ce or La and Ce mishmetal) ternary master alloy; Add pure magnesium in the zinc pond, treat that pure magnesium dissolves fully; Then homemade Zn-Al-RE ternary master alloy is added above-mentioned containing in the zinc pond of magnesium, standing after Zn-Al-RE ternary master alloy dissolves fully; Pour into the Zn-Al-Mg-RE zinc ingot metal in graphite jig.
Need to be appreciated that, in the technical program, the add-on of each alloying element is to determine according to needs of production, is not the restriction to the claimed technical scheme of the present invention.Technological core of the present invention is by interpolation step and order reasonable in design, makes the metallic element with different solubilities all can jointly be dissolved in zinc liquid, and finally forms stable Zn-Al-Mg-RE quad alloy zinc ingot metal.
Preferably, preparation Zn-Al-RE (La, Ce or La and Ce mishmetal) ternary master alloy concrete steps are: by pure spelter heat fused, then zinc liquid temperature is elevated to 460-500 ℃, add fine aluminium, standingly treat that fine aluminium fully dissolves, then zinc liquid temperature is increased to 520-540 ℃, finally rare earth is added in zinc liquid, standing after rare earth dissolves fully, pour into Zn-Al-RE ternary master alloy in graphite jig.
Preferably, Zn-Al-Mg-Re (La, Ce or La and Ce mishmetal) quaternary zinc ingot metal preparation process: pure spelter heat fused is formed to the zinc pond, then the temperature in zinc pond is elevated to 480-500 ℃, purer magnesium is dropped into to the zinc pond, treat that it dissolves fully, finally add Zn-Al-La (La, Ce or La and Ce mishmetal) ternary master alloy, standing 30 minutes, rare earth dissolved fully, stirred, drag for the foreign material such as surface scale, pour into zinc ingot metal in mould.In order to obtain speed of cooling and the purity that guarantees alloy zinc ingot faster, select graphite jig.
Preferably, described finished product mould is graphite jig.This graphite jig can guarantee the purity of Zn-Al-Mg-RE zinc ingot metal.
The present invention, by adopting technique scheme, has following advantages than existing Zn-Al-Mg-RE zinc ingot metal preparation method:
(1) preparation method of the present invention is in the situation that lesser temps and the gas that do not need protection, add pure magnesium in zinc liquid, thereby avoided to adding the severe oxidation that magnesium occurs in high temperature zinc liquid, dieseling has even also increased the specific absorption of magnesium simultaneously;
(2) preparation method of the present invention adds rare earth element at a lower temperature in zinc liquid, and the oxidation and the dieseling that while having avoided adding rare earth element in zinc liquid, have occurred have improved the specific absorption of rare earth element in addition.
Therefore Zn-Al-Mg-RE zinc ingot metal preparation method of the present invention has low, safe, the efficient advantage of service temperature, can greatly reduce the preparation cost of Zn-Al-Mg-RE quad alloy zinc ingot metal, has extraordinary economic outlook.
