Description
Technical field
the present invention relates to battery field, particularly a kind of grid plate preparation method.
Background technology
number are 00109617.6 the disclosed a kind of lattice plate of lead-acid accumulator of patent of invention like Chinese patent, and the screen mould that is adopted in its preparation process often is cast iron screen mould.
yet, it is bonding that cast iron and lead-containing alloy are prone to, therefore; It is bonding to prevent lead-containing alloy and wall of die cavity that the wall of die cavity of being everlasting is sprayed with cork powder; Yet the setting of cork powder makes that the lead-containing alloy cooling velocity is slow, causes production efficiency low; Simultaneously cork powder be arranged so that the screen rough surface that makes, Density Distribution is inhomogeneous, causes the screen quality that makes low; The while cork powder is prone to come off, scaling loss, causes the screen size instability that makes.
Summary of the invention
the purpose of this invention is to provide a kind of grid plate preparation method, adopt the prepared screen quality of the present invention high, and the relative background technology of production efficiency obviously improves.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme: a kind of grid plate preparation method, and it may further comprise the steps successively:
(1) prepares liquid lead-containing alloy;
(2) the liquid lead-containing alloy of step (1) gained is poured in the nickel-base alloy system screen mold cavity;
(3) cooling: adopt the gasified water cooling;
(4) demoulding.
as of the present invention preferred, and the percentage by weight of composition and each composition of nickel-base alloy of processing the screen mould is following: nickel: 80-90%, manganese: 0.2-1.0%; Chromium: 0.2-0.5%; Titanium: 0.1-0.25%, carbon: 0.03-0.14%, all the other are iron.
as of the present invention preferred, and the percentage by weight of composition and each composition of nickel-base alloy of processing the screen mould is following: nickel: 86%, and manganese: 0.5%, chromium: 0.25%, titanium: 0.15%, carbon: 0.06%, all the other are iron.
As of the present invention preferred, the process of step (1) is following:
A, elder generation obtain raw material by weight percentage: calcium: 0.07-0.15%, and aluminium: 0.016-0.04%, bismuth: 0.08-0.26%, silver: 0.1-0.25%, copper: 0.09-0.25%, tin: 1.0-2.0%, all the other are plumbous;
B, aluminium and calcium is put in smelts to fusing insulation in the lead pan;
C, with all the other raw materials be put in be heated to fusing in another crucible and stir after, pour ingot mould into, leave standstill and be cooled to solid-state intermediate alloy, take out;
d, gained intermediate alloy among the c be put in the lead pan among the b be heated to fusing, and stir, lead-containing alloy.
as of the present invention preferred, the temperature of gasified water described in the step (3) is that 100 degree are to 180 degree.
In sum, the present invention has following beneficial effect:
1, adopts nickel-base alloy system screen mould, solved lead-containing alloy and be prone to and the bonding problem of die cavity inwall, therefore; Need not to adopt again cork powder; Make lead-containing alloy behind the nickel-base alloy system of inflow screen mold cavity, can cool off fast that background technology has improved production efficiency relatively;
2, directly contact with nickel-base alloy system screen wall of die cavity owing to lead-containing alloy, and not bonding, therefore, adopt the prepared screen smooth surface of the present invention, Density Distribution is even, and dimensional stability is high, and quality is high;
3, the screen mould in the background technology is a cast iron, and often there is more pore cast iron inside, therefore, when adopting background technology to prepare screen, often adopts the mode of electrode temperature control to keep the screen mold temperature about 200 degree, and energy consumption is big; The nickel-base alloy system screen mould that the present invention adopts, its inside is closely knit, therefore, adopt and constantly charge into temperature in the nickel-base alloy system screen mould be 100 degree to 180 gasified waters of spending to cool off the mode of lead-containing alloy, relative background technology energy consumption reduces greatly;
4, the material of screen mould adopts nickel-base alloy, makes the screen mould can bear the frequent alternate of high low temperature, and it is little to make that the screen mould in use is out of shape, and is difficult for oxidation;
5,, make the good heat conductivity of screen mould because the existence of nickel, iron;
6, because the existence of manganese, chromium makes screen die surface hardness high.
