Ferrite how to make? Ferrite permanent magnet production process

The preparation methods of ferrite magnet is what look like? What are the procedures? Today, Ricky magnet manufacturer to introduce in detail, satisfy your curiosity. Below for ferrite production process flow diagram 1, weighing and mixing ferrite materials including the main raw material, additives and flux Fe2O3, BaCO3, SrCO3 and CaCO3 is the main raw material of ferrite. Weighing process need to strictly follow the formula, otherwise unable to obtain the ideal magnetic energy. After weighing the raw materials mixed in special equipment. Composition uniformity is based on the mixing process. There are many factors influencing the uniformity of mixture components. 2, in order to ensure the smooth progress of solid instead should process, need to mix before presintering granules in the process of granulation, solution into the mixture. The diameters of the pellet material pre burn time. 3, presintering presintering's aim is to fully guarantee the raw material of solid phase reaction, presintering after most of the raw material will be transformed into presintering ferrite phase process will also improve the deformation, shrinkage and density. Described presintering powder can be used as sintering of bonded magnets, magnet and absorbing material) now most of the ferrite manufacturers direct purchase from sintering powder. 4, ball mill in this step, presintering material will be crushed into fine powder. Crushing process will be completed by the ball mill equipment grinding media for ball and water. 5, molding on the basis of the traditional classification method, ferrite magnets can be divided into two categories, isotropic and anisotropic. Ferrite forming method is divided into wet and dry process two kinds. Molding process technology intensive. 6, sintering and other types of sintered magnets, sintering step is very important for ferrite magnet first, sintering process affects the microstructure of ferrite and thus can affect ferrite magnetic not reasonable sintering parameters can lead to a magnet crack, bubble and deformation. 7, mechanical processing of ferrite magnet processing methods including grinding, polishing, cutting and punching. It is worth mentioning, because of ferrite is insulation material, so the magnet manufacturer grinding wheel will be used in the cutting step. Above is the production process of ferrite is introduced, ferrite permanent magnet procurement, quotation, wholesale welcome contact CARDS Ricky.
