Description
The invention belongs to the preparation method of slab lattice alloy of lead-acid battery.
Developing rapidly of maintenance-free lead accumulator, particularly sealed lead-acid battery is surging forward the research of low antimony and plumbous calcium grid alloy in recent years, but detailed technology report also seldom.The exploitation maintenance-free lead accumulator, requirement has good mechanical property, resistance to abrasion is good, and the high alloy of the overpotential of hydrogen, to replace the lead-antimony alloy that the antimony amount is 5-7% that contains of present extensive use, guarantee the non-maintaining effect of battery, in order to satisfy the needs that charge and discharge deeply, usually anodal the employing hanged down antimony, and negative pole adopts plumbous calcium.United States Patent (USP) 4627961 prescriptions are Pb-0.1% Ca-0.03%Al, United States Patent (USP) 4207097 prescriptions are Pb-0.1-3.0%Sn-0.01-0.1Al-0.1-0.3%As-0.002-1.0Cd, United States Patent (USP) 4125690 prescriptions are Pb-0.075-0.13%Ca-0.005-0.99Sn-0.0001-0.1%Al, these prescriptions all do not add Na and are Pb-Ca-Sn-Al, and the prescription of Deutsche Bundespatent GB2096639 is Pb-0.09-0.105%Ca-0.004-0.009%Na, Pb-0.125%Ca-0.004%Na,-0.003%Al, this prescription Na, the content of Al is low, do not add Sn, its process conditions are to add NaOH in fusion of lead, add sodium subsequently, add plumbous calcium foundry alloy at last.
The objective of the invention is in the Pb-Ca-Sn-Al alloy, to add Na, form prescription and be Pb-Ca(0.08-0.12%)-Sn(0.1-0.3%)-Al(0.016-0.05%)-Na(0.01-0.07%) system, adopt surface dopant, make the hardness height at a lower temperature, intensity and elongation all are better than the Pb-Ca-Sn-Al alloy, and the good a kind of NEW Pb calcium grid alloy of casting properties.
Manufacture method of the present invention is: lead is melted; temperature maintenance is under 280-350 ℃ of nitrogen protection; the pure sodium of Pb-Na alloy total amount 2% is put into stainless steel bell jar with holes on every side; be pressed in the molten lead; stirred 2-3 minute; stop logical nitrogen, take out bell jar, pour in the mould Pb-Na2% foundry alloy stand-by.
Adopt the way that adds aluminium in order to make calcium be difficult for scaling loss, make it form layer oxide film on plumbous liquid surface in refining process, calcium is not oxidated in the protection lead, adds charcoal again in plumbous liquid surface, and such duplicate protection reaches more than 90% the yield of calcium.
Because plumbous fusing point height is difficult to vertical connecing is added in the lead-calcium alloy, makes the foundry alloy of Sn85.7%-Al14.3% earlier for this reason.Its preparation method is that the pure tin fusing with 85.7% is warmed up to 480 ℃, adds 14.3% aluminium, slowly is warmed up to 550 ℃, treats that aluminium all melts, and stirs 1-2 minute, takes out stand-by.
The present invention's prescription is Pb-Ca(0.08-0.12%)-Sn(0.1-0.3%)-Al(0.016-0.05%)-Na(0.01-0.07%) preparation process of application alloy is: according to the total amount and the required each component content of want gold conjugate; calculate used pure plumbous amount; lead is put into lead pan to be melted; temperature is raised to 480-510 ℃ after treating fine melt; content by Sn is the amount adding Sn-Al foundry alloy of 0.1-0.3%; (at this moment the content of Al is 0.016-0.05%); after the fusing; add charcoal protection on plumbous liquid surface; maintain the temperature at 480-510 ℃; content by the gold conjugate Na of institute is that 0.01-0.07% calculates the corresponding Pb-Na2% foundry alloy of adding; with institute gold conjugate Ca content be that 0.08-0.12% calculates and adds the Pb-Ca2% foundry alloy; stirred 2-3 minute; can carry out the casting of craft or machine; 480-510 ℃ of plumbous liquid temp, mold temperature 180-210 ℃.
The addition of sodium of the present invention must not surpass 0.077%, and the crystal boundary enrichment phenomenon of sodium can take place when the content of Na reaches 0.1%, influences the intensity of alloy, hardness, and elements of Na sees Table 1 to the lead-calcium alloy Effect on Performance.Content reaches the crystal boundary enrichment phenomenon that sodium can take place at 0.1% o'clock, causes the intensity of alloy, and downward trend appears in hardness.
