Abstract
The present invention relates to a smelting method for manufacturing slab lattice alloy for a maintenance-free lead-acid accumulator. Besides antimony with lower content is added in alloy, copper, arsenium, tin, selenium, sulfur and other elements are also added according to a proper proportion. The added elements are first filled in a special tank and arranged at the bottom of a furnace during smelting, and then lead is added in the furnace; a temperature is maintained after heated to a certain temperature, the elements are mixed and smelted uniformly, an ingot is cast after still, and a mould is raised after temperature drop. Slab lattice smelted and cast by the alloy can be used for manufacturing an accumulator having favorable performance, the technical and economic indexes of the accumulator all achieve a higher advanced level, water consumption reaches 2 to 15, net profit reaches more than 25 yuan per kva hour, and benefit is obvious.
Description
The present invention relates to a kind of smelting process of alloy, particularly about the smelting process of slab lattice alloy of lead-acid battery.
In the lead acid cell production, a kind of non-maintaining or safeguard that less the lead acid storage battery pool technology has caused extensive attention and application.The maximum characteristics of this technology are that its content high antimony (more than 4%) alloy as compared with the past of making antimony in the lead antimony alloy of grid has bigger reduction (it is many 2,5～3% now to contain antimony).But, when containing the antimony amount in the grid alloy when low, can produce in its production process following defective-castability relatively poor, when crystallization the dendritic coarse-grain of easy generation tree, its intensity inductile difference and fragility is big and corrosion-resistant self-discharge phenomenon is serious etc. down.In order to overcome above-mentioned deficiency, the best contains the antimony amount in seeking alloy, also should add the selenium element of energy crystal grain thinning.But, because the proportion of selenium is little, boiling point is low, selenium can't be added lead antimony alloy with general smelting process.For this reason, through looking into following relevant documents and materials;

(10) " MODRN BATTERY ALLOYS " JEMANDERS.ZINC AND LEAD ASIAN SEEVICE OCTOBER 1984 etc.On the basis of above-mentioned document and experiment and 89108668.8 applications " smelting process of Se-containing alloy ", propose-the objective of the invention is to seek to make the smelting process of lead antimony alloy of non-maintaining (containing low antimony) battery grid and the mix proportion scheme of relevant element thereof.
Make by the present invention outside the grid alloy deleading and antimony of lead acid cell, also should be added with elements such as tin, copper, arsenic, selenium, sulphur, its said smelting process is to carry out according to following processing step;
(1), calculates the addition of elements such as antimony, copper, arsenic, tin, selenium, sulphur respectively by the gross weight of casting grid alloy and the above-mentioned various elements and the selected suitable proportion thereof that will add.Wherein also should calculate in lead-arsenic-copper mother liquor the weight of the lead (2) that should add in the weight of plumbous (1) and the alloy gross weight.
(2) by the aforementioned calculation result jar specials of packing in the lump such as the antimony of weighing, copper, arsenic, tin, selenium-tin alloy are placed on the smelting furnace inner bottom part, then lead (1) material are put into stove, be warming up to 590～600 ℃ and be incubated 50～60 minutes and be stirred to fine melt.Wherein, said selenium-tin alloy is to be smelted in advance by 89108668.8 methods of applying for.(3) leading (2) is warming up to 510～530 ℃ and adds sulphur with jar special, and then insulation 15 minutes and be stirred to the sulphur fine melt after being warming up to 530～550 ℃.Be cast into ingot after static 10 minutes, but depanning when treating that die temperature is reduced to 150 ℃ of left and right sides.
Need illustrate that to above processing step some is as follows;
(1) antimony, copper, arsenic, tin, selenium, sulphur are packed in advance jar special and place the purpose of furnace bottom be make proportion less than each element of lead meltable be unlikely to become in plumbous liquid be scum silica frost.
(2) weight percent of each element proportioning is as follows in the alloy; Antimony is 1.6～2.0%; Copper is 0.05～0.07%; Selenium is 0.020～0.030%; Arsenic is 0.17～0.27%; Tin is 0.20～0.30%; Sulphur is 0.0060～0.0070%; All the other are plumbous.
(3) be radix all in the aforementioned calculation with required alloy gross weight.Wherein, plumbous weight should be that the alloy total amount deducts the weight of closing that all add element, also promptly equals above-mentioned lead (1) and adds closing of lead (2).It should also be noted that the lead material in the alloy can be that pure plumbous material also can be reduction plumbous (being a scrap lead) material, and general how plumbous with reduction.If to reduce lead is example, because of wherein having contained some above-mentioned interpolation element, so, before the melting new alloy, calculate should deduct in the content that respectively adds element and reduce the content that has element in the lead.
(4) in the calculating before the melting as when finding to add lead (2), illustrate that the content of lead in the mother liquor is enough, then no longer add lead (2) during melting for negative value.Otherwise, when be on the occasion of the time should add by the amount of calculation result.
(5) for making the above-mentioned element that respectively adds be fused to mother liquor smoothly when the melting and use jar special.Said jar special is to be divided into trilaminar in its of a steel and to be shaped on the cylindricality jar of lid and bottom, all is shaped on the hole that can pass through plumbous liquid on its tank skin and the material baffle and at jar the end.Its objective is when lead is melt into liquid earlier, can go into jar internal heating until the fusing of other element and lump together, go out to mix with mother liquor in the stove and stir evenly through this orifice flow again through this orifice flow.
(6) cast panel technology is model rule commonly used (summary).
Through grid, not only obtained the good advanced person's of manufacturing property maintenance-free battery, and this technology also can be used for making bearing metal with the aforesaid method founding.Its economic and technical norms have all reached higher and the level advanced person.Wherein, tensile strength reaches 3,02(kg/mm
2); Yield strength reaches 2,81(kg/mm
2); Unit elongation is 6,8%; Linear shrinkage ratio is 0,75%; Volumetric shrinkage is 3,79%; Hardness (Bu Shi) 4,8; Good weldability; Resistivity is 2,265 * 10
-7Ω m; Corrosion speed is 0,303 * 10
-4(g/Ancm
2); Overpotential of hydrogen evolution can reach Tafef
A=0.892V B=0.14V; Overpotential for oxygen evolution can reach works as
; The water consumption reaches 2,15(g/Ah).
With existing market, but reach more than 25 yuan with the grid of this law casting clear profit than with every kilovolt-ampere of the grid of other alloy manufacturing the time, its economic benefit is considerable.
Figure of description is disclosed to be the partial schematic sectional view of above-mentioned jar special, and 1 is tank body among the figure, and 2 for placing the boss of material baffle, and 3 is material baffle, and 4 are lid.Tank wall and bottom surface and material baffle evenly are shaped on through hole, and this jar is made of a steel.
Be to implement the present invention, now be base-material and be example to reduce lead, provide the proportioning and the batching data (method of calculation slightly) of one group of the best with 1000 kilograms of alloys of melting in conjunction with above-mentioned processing step.
