Manufacturing process of soft magnetic ferrite core
The invention provides a manufacturing process of a soft magnetic ferrite core. The preparation method comprises the following steps: taking Fe2O3, Mn3O4 and ZnO as raw materials, and carrying out primary ball milling, pre-sintering, secondary ball milling, granulating, primary forming, secondary forming, sintering, cooling and polishing to obtain a soft magnetic ferrite core finished product. The green bodies are tightly arranged and placed in the placing frame in a mutually laminated and stacked mode, and the green bodies are continuously rotated through rotation of the placing frame, so that uniform heating in the green body sintering process is achieved, and the situation that finished products are different in quality level is avoided.
本发明提供一种软磁铁氧体磁芯的制造工艺。本发明将Fe2O3、Mn3O4和ZnO为原料，经过第一次球磨，预烧，第二次球磨，造粒，一次成型，二次成型，烧结，冷却和打磨制得软磁铁氧体磁芯成品。本发明将生坯通过相互叠层、堆放的方式紧密排列放置在放置框中，并且通过放置框的转动，使得生坯不断转动，从而实现生坯烧结过程中受热均匀，避免成品质量层次不一。
