Magnetic field annealing furnace experimental apparatus

Abstract

The invention discloses a magnetic field annealing furnace experimental apparatus. The magnetic field annealing furnace experimental apparatus comprises a furnace body, heating assemblies and magnetizing assemblies, and the heating assemblies and the magnetizing assemblies are sequentially arranged outside the furnace body in an encircling manner; the furnace body is a pipe body with the two ends open; the two ends of the furnace body are provided with end covers; the furnace body is internally provided with an in-furnace feeding area; the furnace body is a silicon carbide muffle pipe; each heating assembly comprises an electric resistance wire, a thermocouple and a temperature control meter; the thermocouples and the temperature control meters jointly control the temperature of the electric resistance wires; each magnetizing assembly is a magnet exciting coil; and the magnet exciting coils are wound outside the heating assemblies. In the magnetic field annealing furnace experimental apparatus, the silicon carbide muffle pipe is adopted as the furnace body, the furnace body is made to be high in heating speed and have a very good high-temperature resistant effect, the annealing temperature of the magnetic field annealing furnace experimental apparatus is made to be raised, and the application range of the magnetic field annealing furnace experimental apparatus is widened; and a manner that the coils are wound outside the furnace body is adopted, the size of the magnetic field annealing furnace experimental apparatus is made to be reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of magnetic field annealing, in particular to an experimental device for a magnetic field annealing furnace. Background technique [0002] Magnetic field annealing, also called magnetic field heat treatment, is a treatment method in which materials are heat treated in the presence of a magnetic field and then cooled to room temperature. Annealing under a magnetic field can promote its crystallization, and can effectively change the formation of various defect states and ordered phases in the crystallization process of materials. At the same time, the magnetic field conditions provide a new driving energy for material synthesis, which can change the electrons of reactants. Spin and nuclear spin promote ion diffusion, increase the activation of reactants, and improve reaction selectivity, thereby inducing new physical and chemical changes, and preparing new materials and new material properties that are diffic...

Problems solved by technology

[0003] Generally, the magnetic field for magnetic field annealing is provided by a permanent magnet. When the magnetic field is provided by a permanent magnet, the space for placing the annealing furnace body in the permanent magnet is very small, which limits the size of the annealing furnace, resulting in the shape of the furnace body larger size
