Description

technical field [0001] The invention relates to the technical field of soft ferrite processing, in particular to a soft ferrite powder sintering device. Background technique [0002] Soft ferrite is based on Fe 2 o 3 The main component is ferrimagnetic oxide, which is produced by powder metallurgy. It is widely used in radio electronics industry, precision instrumentation, remote control and automatic control system. It is mainly used in two aspects of energy conversion and information processing. Sintering is the main method of agglomerating soft magnetic ferrite powder, and the metallurgical properties of raw materials can also be improved through sintering. [0003] In the preparation process of soft ferrite, sintering is the most important step. The temperature and time of sintering are also different for the composition of soft ferrite with different ratios. The heat source usually comes from a single direction, which is likely to cause uneven grains in the ferrite s...
