Background technique
Rare earth permanent-magnetic material neodymium iron boron is a kind of important magnetic material, is referred to as " magnetic with excellent magnetic property
King " is widely used in modern industry and electronic technology.In the neodymium iron boron manufacturing, first it is dilute that neodymium iron boron is made in smelting
Native alloy fragment, then NdFeB rear-earth alloy fragment is processed into powder, finally NdFeB rear-earth alloy powder is gathered into
Then type is sintered, be finally cut into required size again and complete.
In the manufacturing process of NdFeB rear-earth alloy fragment, usually first each raw material are smelted into liquid alloy liquid, then
Large stretch of alloy sheet is formed by refining, cooling, then alloy sheet is carried out brokenly by two mutually matched breaker rolls
It is broken to obtain the NdFeB rear-earth alloy fragment of chunky shape.And sintered NdFeB product is before sintering blank into, due to easy oxygen
The characteristic of change, if product is aoxidized before sintering process, will generate very performance so that product storage becomes particularly important
Big negative effect, it is serious it also occur that spontaneous combustion, causes safety accident.
Currently, neodymium iron boron strip alloy sheet after being ground into neodymium iron boron alloy powder, is stored and is poured usually using polybag
Inert gas carrys out starvation storage.And storage of the neodymium iron boron strip alloy sheet before not being ground into neodymium iron boron alloy powder,
If made in such a way that polybag stores and pours inert gas due to neodymium iron boron strip alloy sheet easy damaged polybag
It is revealed at inert gas, is also just unable to reach the purpose of starvation.Thus it is common to use seal box stores, by neodymium
Iron boron strip alloy sheet is put into inside seal box, is then 300~500Pa by being evacuated to vacuum degree, then to sealing
Argon gas is filled with inside case to protect；The oxygen inside seal box can not be thoroughly removed when in this process, due to vacuumizing, because

Its is micro-, thus the storage method is suitable for the production process of most of sintered NdFeB product.But for artificial satellite,
In the specials such as radar, aerospace equipment, nuclear magnetic resonance equipment, therefore, to assure that storage condition is oxygen-free environment, to reach
Oxygen-free environment, generallys use ethyl alcohol, hexane, acetone and other organic solvent to replace inert gas to carry out starvation, to leakproofness
Inside is filled with organic solvent and easily its internal air can be discharged, and ethyl alcohol, hexane, acetone and other organic solvent will not
It is physically or chemically reacted with the generation of neodymium iron boron strip alloy sheet, therefore, can satisfy storage request；But this method there is also
, a large amount of uses of organic solvent following defect: 1), the gross mass of seal box is caused to significantly improve, this can improve subsequent transport
Cost；2), ethyl alcohol, hexane, acetone and other organic solvent are combustibles, and storage condition and transportation environment require height, if operation
It is improper, Yi Fasheng safety accident.

It connects；The capping of the case lid 20 is provided with inlet opening 201, and the top of the case lid 20 is provided with to be connected with inlet opening 201
Liquid feed valve 21, the capping of the case lid 20 are additionally provided with through-hole 202, and the top of the case lid 20 is additionally provided with and 202 phase of through-hole
The exhaust-valve 22 of connection, the capping of the case lid 20 are additionally provided with air inlet 203, the top of the case lid 20 be additionally provided with into
The intake valve 23 that stomata 203 is connected；The side wall of the cabinet 10 is provided with drainage hole 11, and the outside of the cabinet 10 is provided with
The tapping valve 12 being connected with drainage hole 11；The side wall of the cabinet 10 is provided with gas vent 13, and the outside of the cabinet 10 is set
It is equipped with the exhaust valve 14 being connected with gas vent 13.
The metal that the cabinet 10 and case lid 20 are all made of high mechanical strength is made.It opens bolt fastener and makes cabinet 10
It is separated with case lid 20, is then packed into neodymium iron boron strip alloy sheet to the inside of cabinet 10, then covers case lid 20.Utilize diaphragm pump
Organic solvent is transported to the inside of cabinet 10 by liquid feed valve 21, is such as connected to the output end of diaphragm pump with liquid feed valve 21, every
The input terminal of membrane pump is connected to the storage barrel equipped with organic solvent, liquid feed valve 21 and exhaust-valve 22 is opened, in the driving of diaphragm pump
Under, organic solvent is transported to the inside of cabinet 10, when the output end of exhaust-valve 22 overflows organic solvent outward, illustrates cabinet
By organic solvent to being full of, the inner air of cabinet 10 is discharged completely for 10 inside, be then shut off exhaust-valve 22 and into
Liquid valve 21 closes diaphragm pump.Wherein, the organic solvent is one of ethyl alcohol, hexane, acetone；It is described to have in the present embodiment
Solvent is preferably the acetone of low boiling point.Air pump is set between intake valve 23 and argon bottle, opens intake valve 23 and tapping valve
12, while booster air pump, argon gas can be transported to the inside of cabinet 10 by air pump, so that the acetone inside cabinet 10 can
Row outwardly, when the output end of tapping valve 12 is not then exhausted from acetone, closes tapping valve 12, closes intake valve from tapping valve 12
23 and air pump；Exhaust valve 14 is connected to vacuum pump, is then powered to electric hot plate 40, electric hot plate 40, which is powered, generates heat to give
