Sintering process of manganese zinc ferrite magnetic core
The invention discloses a sintering process of a manganese zinc ferrite magnetic core, which specifically comprises the following steps of: (1) sintering a manganese zinc ferrite magnetic core blank in a kiln at the advancing speed of 18-21 minutes per vehicle; (2) the normal temperature is-600 DEG C, and the heating rate is 0.8-1.0 DEG C/min; (3) the temperature is 600-1000 DEG C, the heating rate is 1.5 DEG C/min or above, and air is supplemented; (4) nitrogen is supplemented at the temperature of 900-1000 DEG C; (5) the temperature is 1000-1200 DEG C, and the heating rate is 1.2 DEG C/min; and (6) keeping the temperature at 1250-1400 DEG C and the heating rate at 1.8 DEG C/min. From the perspective of a kiln sintering process, the crystallization problem in the existing manganese zinc ferrite magnetic core production process is solved, so that the prepared manganese zinc ferrite magnetic core product has the excellent characteristics of high impedance, high Q value, high frequency and the like.
本发明公开了一种锰锌铁氧体磁芯的烧结工艺，具体包括以下步骤：(1)将锰锌铁氧体磁芯坯件放置在窑炉内烧结，推进速度为18‑21min/车；(2)常温‑600℃，升温速率为0.8‑1.0℃/min；(3)600‑1000℃，升温速率为1.5℃/min以上，补充空气；(4)900‑1000℃，补充氮气；(5)1000‑1200℃，升温速率为1.2℃/min；(6)1250‑1400℃，升温速率为1.8℃/min，保温。本发明从窑炉烧结工艺的角度出发，解决了现有锰锌铁氧体磁芯生产工艺中存在的结晶问题，从而保证了制得的锰锌铁氧体磁芯产品具有高阻抗、高Q值、高频率等优良特性。
