Production method of permanent magnetic ferrite pre-sintered material
The invention discloses a permanent magnetic ferrite pre-sintering material production method, which specifically comprises: S1, mixing: mixing a permanent magnetic ferrite raw material iron red and a mixed filler, and completely mixing for 30-35 min through a stirring device at a rotation speed of 500-600 r/min to obtain a mixed powder material; the preparation method comprises the following steps: S1, grinding, S3, pulping, S4, dehydrating and drying, and S5, sintering. The invention relates to the technical field of permanent magnetic ferrite production. According to the production method of the permanent magnetic ferrite pre-sintering material, the toughness of a permanent magnet material can be improved by adding the mixed filler into the permanent magnet material, the aim of assisting the grinding degree of permanent magnet raw material particles by adding the filler is well achieved, and the purpose of optimizing the particle size morphology of magnetic powder by adding a low-temperature tempering process is achieved; the orientation degree is improved, the magnetic performance is further improved, the toughness of the permanent magnetic ferrite pre-sintering material is greatly improved, grinding is convenient and sufficient, and therefore the permanent magnetic ferrite pre-sintering material is very beneficial to permanent magnet manufacturing enterprises.
