Abstract
The present invention provides positive and negative grid alloy for making valve controlled lead-acid accumulator plates and a preparing technology thereof, which relates to a manufacturing technology of a lead-acid accumulator, particularly to a technology of valve controlled lead-acid accumulators. Calcium is mixed with lead powders according to the rate of three to one, and then, the calcium and the lead powders are pressed into calcium cake; lead ingots are melted into molten lead; the calcium cake is added in the molten lead, stirred and uniformly mixed; then, tin which accounts for 1% to 1.4% or 0.4% to 0.7% of the quantity to be prepared is added; the rest lead ingots are added, stirred and uniformly mixed, and then, the ingots are cast; the ingots are respectively manufactured into the positive and negative grid alloy of valve controlled lead-acid accumulator plates. The method firstly manufactures the calcium cake and lead cake so that the calcium content of the alloy can realize the addition according to the predetermined quantity, and the purity of the alloy is ensured. The present invention has the advantages of simple production technology, easy control, and stable properties of a valve controlled lead-acid accumulator manufactured by the present invention; the self-discharge rate of the accumulators manufactured by the alloy is greatly less than that of lead antimony alloy. The present invention overcomes the defects in the prior art that the calcium content of the general lead-calcium alloy is difficultly controlled because the general lead-calcium alloy is prepared from master alloy; thereby, the present invention meets the requirements of various indexes for producing the valve controlled lead-acid accumulators.
Description
Technical field
The present invention relates to the manufacturing process technology of lead acid accumulator, particularly the valve-regulated lead-acid battery technology.
Background technology
The positive negative grid alloy of battery is one of key technology of making valve-regulated lead-acid battery, and particularly calcium content is most important.The lead-calcium alloy that prior art is general is many, and its calcium content is difficult to control with the foundry alloy preparation, can't satisfy every index request of producing valve-regulated lead-acid battery.
Summary of the invention
The object of the invention is to provide a kind of positive and negative grid alloy and manufacturing process thereof that is applicable to the valve-regulated lead-acid battery plate.
Be used to make the positive grid alloy of valve-regulated lead-acid battery plate, contain 0.06%～0.13% calcium in the alloy, contain 1.0%～1.4% tin, contain 0.02%～0.03% aluminium, surplus is lead and impurity.
Above-mentioned positive grid alloy, finish by following steps:
A, with calcium and aluminium powder by after 3: 1 mixed, be pressed into the calcium cake;
B, lead pig is melt into plumbous liquid under 480～580 ℃ of conditions;
C, get and account for 62%～67% plumbous liquid of desiring amount of preparation, in plumbous liquid, add to account for and desire configuration amount 0.10%～0.14% calcium cake, after mixing, add to account for again and desire to be configured in 1%～1.4% tin, add the surplus lead pig again, mix the back ingot casting.
Be used to make the negative grid alloy of valve-regulated lead-acid battery plate, contain 0.06%～0.13% calcium in the alloy, contain 0.4%～0.7% tin, contain 0.02%～0.03% aluminium, surplus is lead and impurity.
The alloy of above-mentioned negative grid alloy, finish by following steps:
A, with calcium and aluminium powder by after 3: 1 mixed, be pressed into the calcium cake;
B, lead pig is melt into plumbous liquid under 480～580 ℃ of conditions;
C, get and account for 62～67% plumbous liquid of desiring amount of preparation, in plumbous liquid, add to account for and desire configuration amount 0.10%～0.14% calcium cake, add again to account for after mixing and desire configuration amount 0.4%～0.7% tin, add the surplus lead pig again, mix the back ingot casting.
The present invention makes the calcium content of alloy can realize adding by pre-metering by making the calcium cake earlier, guarantees alloy purity, the present invention not only production technology is simple, be easy to control, and with the storage battery self-discharge rate of this alloy manufacturing much smaller than lead-antimony alloy, the valve-regulated lead-acid battery stable performance of making.
The used aluminium powder fineness of above-mentioned technology is 100～200 orders.
The calcium cake diameter of suppressing in the above-mentioned technology is 58～62mm.
For each composition can quick, fully be mixed, the hot melt the bottom of a pan that the calcium cake is pressed into plumbous liquid makes the blast of calcium cake be mixed in plumbous liquid.
For realizing quickly mixing, mixing speed is 100～200 rev/mins among the present invention.
