Description
Technical field
The utility model is related to magnetic powder processing technique field, specifically a kind of amorphous powder core sintering furnace.
Background technology
Sintering is powder or powder compact is heated to the temperature less than the wherein fusing point of basis, then with certain side
Method and speed are cooled to the process of room temperature.It is being sintered that the result is that being bonded between powder particle, the intensity of sintered body increases,
The aggregation of powder particle is turned into the agglomerate of crystal grain, to obtain the product or material of required physics, mechanical performance.
Amorphous powder core is added by a series of link such as the insulation of powder, passivation, compacting, heat treatment, cooling procedure
Work forms, to reach required magnetic property, heat treatment and cooling link especially important during entire.Due to amorphous
Material is extremely sensitive to temperature, and cooling procedure after heat treatment is directly cooling in air or makes magnetic powder using water-cooling system
Core is cooled to room temperature by heat treatment temperature, and since temperature change is uneven, band will generate stress because of Imbalance in weight, non-
The magnetism of brilliant powder core is very sensitive to stress, and the stress in the amorphous powder core of production cannot completely remove, and cause amorphous magnetic
The magnetic property of powder core is poor.
