preparation example Construction

[0023] A preparation method of manganese zinc soft ferrite material as claimed in claim 1, the method steps are as follows:

[0024] (1) Powder manufacturing:

[0025] A. Ingredients: Add the main components into the ball mill in proportion, and mix them evenly with the oxide wet process;

[0026] B. One-time spray granulation: After ball milling, the mixed material that is stirred evenly is added to the spray tower for spray granulation;

[0027] C. Pre-burning: pre-fire the sprayed primary material in a rotary kiln at a temperature of 780°C to 920°C, and the pre-burning time is 45 to 60 minutes. Use an oxygen-enriched environment during pre-firing, and use a blower to introduce air into the kiln to pre-synthesize the main components and increase the degree of magnetization;

[0028] D. Doping: put the calcined material into a sand mill, add a modifier, and carry out sand milling. Pay attention to controlling the particle size of the slurry to 1.2-1.6 μm;

[0029] E. Secon...

Embodiment 1

[0037] A kind of preparation method of manganese zinc soft magnetic ferrite material, the method steps are as follows:

[0038] (1) Powder manufacturing:

[0039] A. Ingredients: The main components are added into the ball mill and uniformly mixed by oxide wet process. The main components are composed of 52.3% Fe2O3, 6.8mol% ZnO and the balance of Mn3O4. The content of the main components is 100mol%.

[0040] B. One-time spray granulation: After the ball is milled, the evenly stirred mixture is added to the spray tower for spray granulation.

[0041] C. Pre-burning: pre-fire the sprayed primary material at a temperature of 850°C in a rotary kiln, and the pre-burning time is 45 minutes. During pre-firing, blow air into the kiln with a blower to pre-synthesize the main components and increase the degree of magnetization as much as possible.

[0042] D. Doping: Put the calcined material into a sand mill, add a modifier, and carry out sand milling. Pay attention to controlling t...
