Background
The iron is magnetic because the movement of free electrons inside the iron has certain directionality. However, at a high temperature of 600 ℃ or higher, the direction of the internal free electrons is disordered and becomes nonmagnetic. When the temperature is reduced between 700 ℃ and 400 ℃, the surface temperature of the magnet is rapidly reduced, the heat in the magnet is not released in time, and the temperature difference exists between the inside of the magnet and the surface of the magnet, so that the movement direction of electrons in the magnet is from inside to outside to form a certain order, and a weaker magnetic field is generated on the surface of the magnet, and the phenomenon of magnetic entrainment or residual magnetism occurs. When the temperature is below 300 ℃, the Brownian motion is relatively weakened, the moving direction of free electrons is basically fixed, and the magnetic influence on the magnet is relatively weak. In the prior sintering process of most ferrite magnets in China, products sintered on each plate are subjected to wet pressing and blank arranging for 2-3 layers, and are subjected to dry pressing even for 4-5 layers. The magnet swinging plates are too dense, so that the cooling effect of the product in a cooling area is poor, the surface temperature of the magnet at the furnace outlet is about 120-150 ℃, and the collection and boxing operation of workers are inconvenient. In order to lower the temperature more quickly, air is blown into the furnace to exchange heat with the furnace so as to achieve the effect of temperature reduction. Thereby making the magnet susceptible to magnetic carryover, especially in the case of bar and block magnets. When the magnet is provided with the magnet, foreign matters are easy to adhere to the magnet when the motor is assembled, and bad hidden troubles are brought to the motor.
