Abstract
The invention relates to the technical field of rare earth processing, in particular to a temperature measuring flange for neodymium-iron-boron sintering. The temperature measuring flange for neodymium-iron-boron sintering comprises a support. Thermocouples are arranged on optional joints of the support and are electrically connected with an external detection controller. The temperature measuring flange has the advantages that the temperature measuring flange is simple in structure, temperature differences among the joints are measured and calculated in a balanced manner by a stereoscopic multi-point temperature acquisition method, a distribution form of products inside a sintering furnace is optimized, and the quality of the products is effectively improved.
Description
Technical field
The present invention relates to the rare earth processing technique field, particularly a kind of NbFeB sintered thermometric flange.
Background technology
The at present development of rare earth permanent-magnetic material is very rapid, is widely applied in a lot of fields, becomes the valuable cargo basis of up-to-date technology; Rare earth permanent-magnetic material is divided into rare-earths-cobalt system and the large class of Nd Fe B alloys two, and the Nd Fe B alloys that adopts sintering process to produce not only has very high remanence strength, very high magnetic energy product, and have very high coercive force, this is that current any permanent magnetic material can't be compared.
The steps such as the production procedure of sintered NdFeB is divided into mainly that batching, melting, hydrogen are broken, airflow milling, moulding and sintering, wherein the temperature when sintering directly has influence on the final performance of product; Therefore need to have accurately the actual temperature in sintering furnace in sintering process and control.Be subjected to the impact of the factors such as external insulation material and internal vacuum during sintering furnace work, there is difference in the actual temperature of inner each node of sintering furnace, also there are certain error in the built-in temperature control setting of sintering furnace and actual temperature, and work in-process does that the quality of product is had certain impact.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, a kind of compact conformation, easy to operate NbFeB sintered thermometric flange are provided.
For achieving the above object, the present invention is by the following technical solutions:
A kind of NbFeB sintered thermometric flange of the present invention comprises support, is equipped with thermopair on the arbitrary node of described support, and described thermopair is electrically connected to the detection controller of outside.
Further, described support comprises some vertical rods and full mount structure, and some full mount structures are parallel to each other and corresponding node connects by vertical rod; Be provided with reinforcement arranged in a crossed manner in described full mount structure, be equipped with thermopair on arbitrary intersection point of described vertical rod and full mount structure, the intersection point of reinforcement is provided with thermopair.
Further, also comprise flange, described flange is provided with wire guide, is provided with the compensating wire that connects thermopair and detect controller in wire guide.
Further, described flange is provided with some fixed orifices.
Further, described full mount structure preferably adopts quadrilateral frame.
Beneficial effect of the present invention is: invent simple in structurely, by three-dimensional multipoint temperature acquisition method, the temperature difference between balanced measuring and calculating node is optimized sintering furnace internal product distribution form, has effectively improved the quality of product.
