Description
Technical field
The utility model belongs to sintered NdFeB technical field, is specifically related to the broken reacting furnace of the efficient hydrogen of a kind of neodymium iron boron.
Background technology
Neodymium iron boron is a kind of magnetic material, and as the latest result of rare earth permanent-magnetic material development, neodymium-iron-boron magnetic material is praseodymium neodymium metal, and the alloy of ferro-boron etc., also known as magnet steel.Neodymium iron boron has high magnetic energy product and strong power, and the advantage of high-energy-density makes Nd-Fe-Bo permanent magnet material be applied widely in modern industry and electronic technology simultaneously.
Sintered Nd-Fe-B permanent magnetic material has excellent magnetic property, be widely used in the fields such as electronics, electric machinery, medicine equipment, toy, packaging, hardware machinery, space flight and aviation, comparatively common are magneto, loudspeaker, magnetic separator, computer disc driver, MR imaging apparatus instrument etc., therefore NdFeB material is by a large amount of Development and Production.
The processing step of Development and Production neodymium iron boron is: and batching → melting ingot/get rid of band → hydrogen is broken → die mould → sinter back → and magnetic detection → mill processing → pin cuts processing → plating → finished product.Wherein, the broken technique of hydrogen is the hydrogen absorption characteristic utilizing rare earth intermetallic compound, under Nd Fe B alloys is placed in hydrogen environment, hydrogen enters alloy along rich neodymium phase thin layer, make it expansion explosion and broken, along rich neodymium phase layer place cracking, ensure that the complete of main phase grain and rich neodymium intergranular phase.
Concrete operation step is, pours in reacting furnace, then capping stove, then be filled with hydrogen in reacting furnace, rotational response stove by neodymium iron boron sheet blank, and the neodymium iron boron blank in upset body of heater, makes hydrogen fully contact with neodymium iron boron blank, starts reaction.In current technology, due to the inner wall smooth of reacting furnace body of heater, therefore the upset degree of neodymium iron boron blank is very little, cause reaction speed excessively slow, production efficiency is low, the broken reaction of a stove neodymium iron boron hydrogen complete general need 30 hours and more than, and cause blank to react insufficient.
Utility model content
(1) technical problem that will solve
The broken reaction speed of neodymium iron boron blank hydrogen is slow, production efficiency is low, react incomplete shortcoming in order to overcome for the utility model, and the technical problems to be solved in the utility model is to provide that a kind of reaction speed is fast, productivity ratio is high, react the broken reacting furnace of the efficient hydrogen of neodymium iron boron more fully.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides the broken reacting furnace of the efficient hydrogen of so a kind of neodymium iron boron, comprises body of heater, dividing plate, center-pole;
Dividing plate is distributed in furnace body inside, and center-pole is arranged on body of heater central authorities, the rotating shaft coaxle of center-pole and body of heater.
Preferably, the quantity of described dividing plate is 5 to 7.
Preferably, described body of heater shape is horizontal cylinder.
Operation principle: load neodymium iron boron blank and hydrogen in reacting furnace after, rotating furnace, the dividing plate of furnace body inside is also along with rotation, blank is raised to eminence by dividing plate, downward-sloping with rear bulkhead to certain height, blank above down drops owing to being subject to gravity, is dispersed in the middle of hydrogen, reacts more fully with hydrogen.
When blank drops on central shaft, clash into central shaft, improve crushing efficiency, and the blank fallen can be divided into both sides by central shaft falls, therefore the area that blank contacts with hydrogen is more increased, further increase production efficiency, a stove neodymium iron boron blank hydrogen broken reaction deadline can be contracted to 20 to 25 hours.
(3) beneficial effect
The utility model is in the original structure technically improving reacting furnace, make it in the broken course of reaction of hydrogen, increase the contact area of blank and hydrogen, simultaneously by increasing the crushing efficiency of blank with the collision of center-pole, improve reaction speed, reduce the reaction time, strengthen production efficiency, also make reaction more abundant, device structure is also extremely simple simultaneously.

Dividing plate 2 is distributed in inside body of heater 1, and center-pole 3 is arranged on body of heater 1 central authorities, and the rotating shaft coaxle of center-pole 3 and body of heater 1, the quantity of described dividing plate 2 is 5 to 7.
embodiment 2
A kind of neodymium iron boron broken reacting furnace of efficient hydrogen, comprises body of heater 1, dividing plate 2, center-pole 3;
Dividing plate 2 is distributed in inside body of heater 1, and center-pole 3 is arranged on body of heater 1 central authorities, and the rotating shaft coaxle of center-pole 3 and body of heater 1, the quantity of described dividing plate 2 is 5 to 7, and described body of heater 1 shape is horizontal cylinder.
Operation principle: load neodymium iron boron blank and hydrogen in reacting furnace after, rotating furnace 1, dividing plate 2 inside body of heater 1 is also along with rotation, blank is raised to eminence by dividing plate 2, downward-sloping with rear bulkhead 2 to certain height, blank above down drops owing to being subject to gravity, is dispersed in the middle of hydrogen, reacts more fully with hydrogen.
When blank drops on central shaft, clash into central shaft, improve crushing efficiency, and the blank fallen can be divided into both sides by central shaft falls, therefore the area that blank contacts with hydrogen is more increased, further increase production efficiency, a stove neodymium iron boron blank hydrogen broken reaction deadline can be contracted to 20 to 25 hours.
