Abstract
The utility model discloses a melting kettle that dry process was made, including the setting that is the tube -shape the interior crucible of inboard, cladding setting at the outer extrernal resistance magnetism pot of crucible, in setting up between crucible and the extrernal resistance magnetism pot and compacted lift that be the tube -shape setting, set up the clamp plate on the intraformational spiral of compaction crucible and extrernal resistance magnetism pot upper portion around the square water -cooling copper coil established and including setting up, the lower part of clamp plate is equipped with to arrange in to be equipped with between interior crucible bead and the extrernal resistance magnetism pot along mouth seals the layer. The utility model discloses a structure reduces ethyl orthosilicate's use by a wide margin, has shortened the baker time widely, and the easy split of this crucible structure has moreover reduced master worker's working strength.
Description
Technical field
The utility model relates to a kind of smelting equipment of sintered NdFeB, particularly relates to the melting kettle that a kind of dry method is made.
Background technology
At present, sintered NdFeB needs the melting kettle used when melting, melting kettle, after the certain stove number of production and application, needs again to make.
Conventional method, when making crucible, uses similar concrete material to fix crucible.There is following problem in the method: the first, because concrete contains ethyl orthosilicate, and after concrete need being dried, smelting furnace could use, and furnace drying time is about 3 days.
If the second furnace drying time is too short, will to crack etc., the problem such as crucible damage.The wherein furnace drying time of 3 days, had both wasted a large amount of electric energy, had delayed again production.In addition, crucible is fixed very solid by concrete, when next time tears stove open, wastes time and energy.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes the melting kettle that a kind of dry method is made.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: the melting kettle that a kind of dry method is made, comprise tubular be arranged on inner side interior crucible, be coatedly arranged on crucible outer field extrernal resistance magnetic pot, compacted lift that is between interior crucible and extrernal resistance magnetic pot and that arrange in tubular be set, the square water-cooled copper coil of the spiral winding be arranged in compacted lift and be arranged on the pressing plate on interior crucible and extrernal resistance magnetic pot top, the bottom of described pressing plate is provided with to be placed between interior crucible bead and extrernal resistance magnetic pot edge mouth and is provided with sealing layer.
Described interior crucible is alumina crucible, and described extrernal resistance magnetic pot adopts soft magnetic ferrite to make, and described compacted lift adopts high-strength wear-resistant pouring material compacting to build up.
Described sealing layer is concrete layer, and this concrete layer is made up of high-strength wear-resistant pouring material and ethyl orthosilicate inserts, and the weight ratio of described high-strength wear-resistant pouring material and ethyl orthosilicate inserts is 10:1.
Compared with prior art, the structure of the product that the utility model adopts is novel, and the compacted lift of employing and sealing layer firmly can fix interior crucible and extrernal resistance magnetic pot, and pressing plate prevents alumina crucible to loosen further, plays reinforcement effect.And the high-strength wear-resistant pouring material in compacted lift can reuse, save material, significantly reduce ethyl orthosilicate consumption, such structure syndeton is easy to interior crucible to be separated with remainder, fast changeable alumina crucible.And in the concrete layer on top, only contain ethyl orthosilicate, shorten furnace drying time widely, the furnace drying time comparing the melting kettle of conventional construction at least shortens 1/4th, improves operating efficiency, also greatly reduces the waste of the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the melting kettle that the dry method that the utility model proposes is made, it is characterized in that: comprise tubular be arranged on inner side interior crucible 1, be coatedly arranged on crucible 1 outer field extrernal resistance magnetic pot 2, compacted lift 3 that is between interior crucible 1 and extrernal resistance magnetic pot 2 and that arrange in tubular be set, the square water-cooled copper coil 4 of the spiral winding be arranged in compacted lift 3 and be arranged on the pressing plate 5 on interior crucible 1 and extrernal resistance magnetic pot 2 top, the bottom of pressing plate 5 is provided with to be placed between interior crucible 1 bead and extrernal resistance magnetic pot 2 bead and is provided with sealing layer 6.Interior crucible 1 is alumina crucible, and extrernal resistance magnetic pot 2 adopts soft magnetic ferrite to make, and described compacted lift 3 adopts high-strength wear-resistant pouring material compacting to build up.
Sealing layer 6 is concrete layer, and this concrete layer is made up of high-strength wear-resistant pouring material and ethyl orthosilicate inserts, and the weight ratio of described high-strength wear-resistant pouring material and ethyl orthosilicate inserts is 10:1.
The utility model make use of cold-crucible electromagnetic induction vacuum levitation melting method, its operation principle will the sintered NdFeB raw material of melting be needed to be placed in interior crucible under vacuum, also be in the high frequency of generation sintered NdFeB raw material being seated in square water-cooled copper coil 4 or intermediate frequency alternating electric field, and utilize logical water-cooled alumina crucible as " amplitude transformer " in magnetic field, energy magnetic field energy is made to concentrate in the volume space of alumina crucible, and then the near surface of sintered NdFeB raw material furnace charge forms powerful vortex flow, discharging Joule heat makes sintered NdFeB melting sources on the one hand, forming Loulun magnetism field on the other hand makes sintered NdFeB raw material be that melt suspends (or half suspends) and stirs.Due to maglev effect, the inwall of melt and alumina crucible is disengaged, the heat radiation behavior between such melt and alumina crucible changes into heat loss through radiation by heat loss through conduction, thus causes that radiating rate is poly-to be subtracted.So just make the sintered NdFeB raw material in alumina crucible reach very high temperature, and then be smelted into required sintered NdFeB.
With the structure of traditional crucible unlike being structure of the present utility model, the following outstanding advantages of structure that the utility model adopts: the high-strength wear-resistant pouring material one, in compacted lift can reuse, saves material; Two, significantly ethyl orthosilicate consumption is reduced; Three, be easy to alumina crucible to be separated with remainder, fast changeable alumina crucible; Four, ethyl orthosilicate content is few, and only on top, volatile, furnace drying time shortens to 1/4th of conventional method, and smelting furnace is monthly produced stove number and brought up to 112 stoves from 96 stoves, and namely production efficiency improves 16.7%.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
