Preparation method of permanent magnetic ferrite wet-pressing magnetic shoe
The invention discloses a preparation method of a permanent magnetic ferrite wet-pressed magnetic shoe, which comprises the following steps: carrying out primary ball milling on raw materials to obtain primary slurry, filtering and drying the primary slurry to obtain a material, firing the material, and cooling to room temperature to obtain a primary sintered material; crushing the obtained primary sintered material, and sieving; adding a composite additive into the sieved primary sintered material for secondary ball milling to obtain secondary slurry, and then filtering the secondary slurry to obtain a filter material; the preparation method comprises the following steps: preparing a filter material, carrying out wet pressing molding on the obtained filter material, sintering a sample obtained by wet pressing molding to obtain a secondary sintered material sample, and carrying out coarse grinding processing on the secondary sintered material sample to obtain the magnetic shoe. According to different proportions of grinding media (steel balls and water), on the premise of the same average particle size, the particle size distribution of the slurry is optimized, and the grinding efficiency is improved; slurry more beneficial to forming is prepared, the forming efficiency is improved, and the product percent of pass is increased.
本发明公开了一种永磁铁氧体湿压磁瓦的制备方法，包括以下步骤:将原材料进行一次球磨得到一次浆料，然后将一次浆料进行过滤烘干得到物料，再将物料进行烧制后冷却至室温，得到一次烧结料；将得到的一次烧结料粉碎后过筛；将过筛后的一次烧结料加入复合添加剂进行二次球磨，二次球磨后得到二次浆料，然后将二次浆料进行过滤得到滤料；将得到的滤料进行湿压成型，然后将湿压成型得到的样品进行烧制得到二次烧结料样品，再将二次烧结料样品粗磨加工，得到磁瓦，本发明通过对研磨介质(钢球、水)的不同配比，在相同平均粒度的前提下优化料浆粒度分布，提高研磨效率，制备更利于成型的料浆，提高成型效率，提高产品合格率。
