Abstract
An ingot casting quick-cooling die for preparing AB2 hydrogen storage alloy belongs to the technical field of mechanical dies. The utility model comprises ingot casting cavities and cooling water cavities, a plurality of hollow flat plate die sheets are arranged at intervals in a frame, one ingot casting cavity is arranged between each two die sheets, an inner cavity of each die sheet is one cooling water cavity and the upper part and the lower part of each die sheet are connected with an inlet pipe of cooling water and an outlet pipe of cooling water through a flexible pipe. The die cools the casting ingot of AB2 hydrogen storage alloy and has easy implementation of discharge, the working hours are shortened, formed materials have good compactness and the cost is reduced compared with the existing ingot dies. The obtained anode materials (casting ingot of AB2 type hydrogen storage alloy) have the advantages of high capacity of hydrogen storage, long cycle life, excellent integrated electrical property, etc. The utility model is suitable for heavy current charge and discharge, can satisfy the requirements for high specific energy nickel-hydrogen batteries, and can satisfy the requirements of electric automobiles for nickel-hydrogen storage batteries.
Description
Technical field
The utility model relates to a kind of Ni-MH battery and the Ni-H 2 power accumulator negative material does not promptly have rare earth AB
2The fast cold mould of the ingot casting of zirconium base hydrogen-storing alloy material belongs to the machine die field.
Background technology
At present domestic and international AB
2The type alloy material is not large-scale production as yet, and main cause is that to adopt the routine casting method to prepare Zr be in the multicomponent alloy process, the solidification cooling of alloy slowly (about 10
2K/s), cause the alloying component segregation, this is the major reason that generates the non-Laves phase of Zr-Ni type in the alloy, because the generation of non-Laves phase must make the content of Laves phase in the alloy (mainly inhaling the hydrogen phase) reduce, thereby the further raising of restriction alloy discharge capacity and cyclical stability.Ingot casting cooling die commonly used is made up of inside and outside mould, and interior external mold is the sandwich cylinder body, and interlayer is the cooling water layer, the cavity that interior external mold forms then is the ingot casting layer, and this kind mold cools down face is less, and cooling velocity is slow, the cooling effect difference and the demoulding need cooperate the stripping operation complexity with driving.
Summary of the invention
The utility model provides a kind of Ni-MH battery and Ni-H 2 power accumulator negative material promptly not to have rare earth AB just in order to overcome above-mentioned deficiency
2The fast cold mould of the ingot casting of zirconium base hydrogen-storing alloy material is with the negative material (AB of this mould acquisition
2Type hydrogen-storage alloy ingot casting) have storage hydrogen capacity height, have extended cycle life, advantage such as comprehensive electrochemical properties excellence, be fit to large current density, can satisfy the requirement of high specific energy Ni-MH battery and electric automobile nickel-hydrogen accumulator.Specifically implement like this: a kind of preparation AB
2Hydrogen-storage alloy is with the fast cold mould of ingot casting, comprise ingot casting cavity, cooling water cavity, it is characterized in that being spaced in the framework the dull and stereotyped matrix of some hollows, form the ingot casting cavity between per two matrixs, each matrix inner chamber is the cooling water cavity, and each matrix connects cooling water turnover pipe by flexible pipe up and down.Because each dull and stereotyped matrix connects cooling water turnover pipe by flexible pipe, can freely be offset in certain angle, is convenient to discharging, the total film-cooled heat of each matrix through assembled arrangement is big in addition, and cooling velocity is fast, good cooling results.The utility model is because ingot mould is two-sided water cooling, and general water inlet pipe is the matrix bottom, and return pipe is matrix top, and material is between two matrixs.The molten state material is poured tundish into from crucible, vertically fall into out feed collet from the blanking port of tundish, forms the as cast condition material by the two-sided recirculated water cooling of each matrix.
Be equipped with flow apron in each dull and stereotyped matrix inner chamber of the utility model, make the interior cooling water of matrix not form the dead angle, guarantee cooling effect.
The flexible pipe that the utility model is connected with matrix can place matrix one side, also can split both sides; Spaced matrix can a row be laid, and also can two rows or two arrange above the laying, and each is arranged and is equipped with dividing plate between matrix.
With mold cools down AB described in the utility model
2The hydrogen-storage alloy ingot casting, man-hour is shortened in discharging easily, the material compactness that forms is good, reduces cost the fast cold mould of this ingot casting greatly than existing ingot mould, cooling all is the crystalline phase tissue of column crystal through cooled ingot casting fast, and conventional casting alloy is because of containing the Zr of 17.5% (quality)
7Ni
9And Zr
9Ni
11Non-Laves phase, the discharge capacity of alloy has only 300mAh/g, only is 38% through the capability retention after 500 circulations, and (cooling velocity about 4.8 * 10 under the rapid solidification mould condition of the present utility model
5K/s), because the generation of the non-Laves phase of Zr-Ni type is effectively drawn up, to coagulate alloy soon and only contain two kinds of Laves of C15 and C14 type mutually, the discharge capacity of alloy can reach 356mAh/g, can reach 80% through the capability retention after 500 circulations, be better than the fast cold mould of conventional ingot casting greatly.
