Abstract
The invention discloses the distribution in a kind of production of neodymium iron boron, during dispensing, multiple batches of raw material equivalent is taken into mixture and is used.The distribution causes that the neodymium iron boron product Central Plains material composition fluctuation of production reduces, and properties of product are evenly, stably.
Description
Technical field
The present invention relates to neodymium iron boron production field, the distribution in more particularly to a kind of neodymium iron boron production.
Background technology
At present, known neodymium iron boron production process include dispensing, melting, broken hydrogen, powder processed, batch mixing, oriented moulding, etc. it is quiet
The multiple working procedures such as pressure, vacuum-sintering, tempering, performance detection, grinding, section, plating, packaging, all be unable to do without per procedure
Handwork.Every block needs the time of one week or so from output is put into, per the control technique and parameter neither phase of procedure
With connecting each other, influencing each other again, the minor variations of period production technology and device parameter all can directly or indirectly influence product
Quality, therefore neodymium iron boron quality management ＆control is a cumbersome elaboration.
Burden process is important link in neodymium iron boron production process.Will be used in the every stove production process of neodymium iron boron several
Plant raw metal, the rare earth metal alloy such as including Nd-Pr, Nd, Ce, Ho-Fe, Dy-Fe, Gd-Fe.Small metal includes B-Fe, Nb-
Fe, Zr, Al, Cu, pure iron etc., must carry out incoming test analysis from materials procurement arrival every time.Further according to product charger sheet,
Dispensing code carries out strict dispensing, for the main raw material(s) Nd-Pr and B-Fe of large usage quantity, the former material of each batch
Material composition is differed, and is differed greatly, and same batch raw material, every barrel of composition there is also difference.At present, raw material during dispensing
Take using the production of single batch dispensing, each stove dispensing takes a batch raw material, one barrel of raw material be finished enable again it is another
Bucket, a batch raw material are finished and enable again another batch, and the product of such dispensing production, composition fluctuation is big, performance difference compared with
Greatly.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the invention, without answering
In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide the distribution in a kind of production of neodymium iron boron, former material in the neodymium iron boron product of production
Material composition fluctuation reduces, and properties of product are evenly, stably.
To achieve the above object, the invention provides the distribution in a kind of production of neodymium iron boron, during dispensing, will be multiple batches of
Raw material equivalent is taken mixture and is used.
Preferably, some buckets are included per batch raw material, during feeding, every barrel of equivalent is taken.
Preferably, during each dispensing, six batch raw material are used.
Preferably, 10 barrels are included per batch raw material.
Compared with prior art, the present invention has the advantages that：Multiple batches of raw material equivalent is taken into mixture to use,
The raw material uniform ingredients for so making, and the fluctuation reduction of product Central Plains material composition, properties of product are evenly, stable.
Specific embodiment
Specific embodiment of the invention is described in detail below, it is to be understood that protection scope of the present invention is not
Limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
The distribution in a kind of production of neodymium iron boron according to the specific embodiment of the invention, during dispensing, by multiple batches of original
Material equivalent is taken mixture and is used.
As a kind of preferred embodiment, some buckets are included per batch raw material, during feeding, every barrel of equivalent is taken.
As a kind of preferred embodiment, during each dispensing, six batch raw material are used.
As a kind of preferred embodiment, 10 barrels are included per batch raw material.
This programme is described in detail with a kind of specific raw material dispensing below：
With reference to burdening calculation, it is assumed that need to be 180Kg with material N d-Pr weight, six batches of existing material N d-Pr,
Numbering is respectively 0001,0002,0003,0004,0005,0006, and each batch has 10 barrels, when dispensing is produced, six batches
Raw material equivalent take, i.e., each batch takes 1/6th, i.e.,：180*1/6=30Kg, per a batch of consumption at 10
Equivalent is taken in bucket, 1/10th of the batch consumption is taken in each barrel, i.e.,：30*1/10=3Kg, so, takes in different buckets
Different batches raw material mixture after, the raw material that as this stove dispensing is used.
To sum up, the distribution in the neodymium iron boron production of the present embodiment, takes multiple batches of raw material equivalent mixture and uses,
The raw material uniform ingredients for so making, and the fluctuation reduction of product Central Plains material composition, properties of product are evenly, stable.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that certain principles of the invention and its reality should
With so that those skilled in the art can realize and using a variety of exemplaries of the invention and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
Claims (4)
