The neodymium iron boron sintering furnace temperature measuring flange comprises a support. Any node on the support is equipped with a thermocouple. All thermocouples are electrically connected with an external detection controller. By using a spatial multipoint temperature acquisition method, the neodymium iron boron sintering furnace temperature measuring flange with simple structure measures and calculates temperature difference between nodes in an equalized manner and optimizes distribution form of products in the sintering furnace, effectively increasing the quality of the product.
Description
Technical field
The utility model relates to the rare earth processing technique field, particularly a kind of NbFeB sintered thermometric flange.
Background technology
The development of rare earth permanent-magnetic material at present is very rapid, has obtained widespread use 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 Nd Fe B alloys two big classes, 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 be current any permanent magnetic material can't compare.
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 sintering the time directly has influence on the final performance of product; Therefore to the actual temperature in the sintering furnace in the sintering process control accurately need be arranged.Be subjected to the influence of 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 influence.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, and a kind of compact conformation, easy to operate NbFeB sintered thermometric flange are provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of NbFeB sintered thermometric flange described in the utility model comprises support, is equipped with thermopair on the arbitrary node of described support, and described thermopair is electrically connected with 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 the 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 the wire guide.
Further, described flange is provided with some fixed orifices.
Further, described full mount structure preferably adopts quadrilateral frame.
The utility model beneficial effect is: utility model is simple in structure, and 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 improved the quality of product effectively.
