Penggunaan Magnet Ferit dalam Medan Akustik
Dalam bidang akustik, magnet ferit digunakan terutamanya dalam pelbagai jenis pembesar suara, seperti fon kepala, fon telinga, pembesar suara, dan mikrofon. Khususnya, ia digunakan untuk gegelung suara, magnet, dan litar magnet. Salah satu sebab mengapa magnet ferit digunakan secara meluas dalam industri akustik adalah ciri-ciri akustiknya yang sangat baik, termasuk kebolehtelapan magnet yang tinggi, kehilangan rendah, dan ketumpatan fluks tepu yang tinggi.
Dalam reka bentuk gegelung suara, magnet ferit biasanya digunakan sebagai magnet kekal. Medan magnet yang kuat boleh memberikan daya magnet yang stabil untuk sistem, yang merupakan faktor penting dalam kepekaan dan impedans peranti akustik. Selain itu, daya paksaan magnet ferit yang tinggi memastikan gegelung suara mempunyai daya pemulihan yang kuat dan tindak balas yang pantas, yang penting untuk bunyi berkualiti tinggi.
Penggunaan magnet ferit dalam litar magnet secara beransur-ansur telah menggantikan bahan lain kerana sifat magnetik yang sangat baik dan kos yang rendah. Magnet ferit boleh memberikan medan magnet yang sangat stabil, yang penting untuk sifat akustik peranti. Berbanding dengan bahan lain, magnet ferit mempunyai tenaga magnet yang lebih tinggi, yang boleh meningkatkan kecekapan sistem.

Keperluan untuk Saiz, Toleransi dan Prestasi
Saiz dan toleransi magnet ferit yang digunakan dalam industri akustik bergantung pada aplikasi khusus dan prestasi peranti yang diperlukan. Secara amnya, saiz dan toleransi magnet ferit harus konsisten dengan keperluan reka bentuk peranti untuk memastikan operasi normalnya.
Keperluan prestasi magnet ferit yang digunakan dalam industri akustik terutamanya termasuk sifat magnet, sifat mekanikal, dan kestabilan suhu. Sifat magnetik magnet ferit adalah yang paling penting, termasuk ketumpatan fluks magnet, kebolehtelapan magnet, coercivity, dan produk tenaga magnet. Sifat mekanikal magnet ferit juga sangat penting, termasuk kekuatan tegangan, kekuatan lentur, dan kekuatan mampatan.
Di samping itu, kestabilan suhu juga merupakan faktor penting untuk dipertimbangkan apabila menggunakan magnet ferit dalam industri akustik. Magnet ferit terkenal dengan kestabilan suhu yang sangat baik, tetapi julat suhu khusus adalah berbeza untuk jenis magnet ferit yang berbeza.
Prospek Pasaran Vietnam dan India dalam Bidang Akustik

Zhongke is committed to becoming a world-renowned supplier of permanent magnet material application solutions in the field of new generation consumer electronics and energy-saving home appliances.
The company's current production process of permanent ferrite magnets is as follows: the purchased pre-fired materials are mixed according to their own formula and ingredients, and after being ball milled by a ball mill, ferrite is produced through steps such as precipitation, wet pressing, sintering, and grinding. Body magnetic tiles, ferrite magnets and other finished products. The specific production process flow chart is as follows:
The strontium ferrite calcined material (the main component is SrFe12O19) is mixed with calcium carbonate, silicon dioxide, strontium carbonate, lanthanum oxide, cobalt oxide and other ingredients according to the formula ratio.
The raw materials are added with water and pulverized by a ball mill to form a slurry, which is placed in a sedimentation tower for precipitation.
The dehydrated material formed by precipitation is made into a green body through an automatic press in a normal air environment.
The raw body is sintered at high temperature into a mature body through a wet-pressed magnetic tile electric-fired roller kiln or a wet-pressed magnetic steel gas-fired roller kiln.
The cooked blank is processed by a fully automatic grinding machine processing line to form a finished product.
The magnetic properties, appearance, size and other indicators of the magnets are inspected, packed and put into storage.
The company has applied and improved a number of advanced technologies in the industry, such as high-performance ferrite slurry stabilization technology and secondary ball milling batching technology, which has solved the quantitative problem of material added in the preparation process. And we use double coupling dispersion and fine grinding to overcome the problems of slurry agglomeration and particle size distribution consistency. The performance of the slurry obtained in the ball milling process is more stable, which reduces the unit operating time of the ball milling equipment, improves product quality, and reduces production costs.
The company uses a unique new green release agent independently developed to prepare magnetic tiles. The new green release agent is an organic combination of microbial technology and surface release treatment technology, which can degrade oil molecules, reduce the oil content of the release agent, and restore the surface. active lipophilic factor. The product is combined with the surface release process, and the release effect of the magnetic tile is improved through a new release agent, and the surface finish of the blank is improved. The demoulding technology has the characteristics of simple preparation method and convenient application, and improves production efficiency.
By transforming the sintering preheating system equipment, the company reduces the water content of the sintered green body in the kiln, greatly reduces the waste rate caused by factors such as cracking and lack of oxygen during sintering, and improves the sintering density and mechanical strength of the product. Obtain good microstructure and magnet properties. The company has also realized the sintering base temperature that products with different performances can adapt to through formula adjustment. Products with different specifications, sizes and performances can be co-fired at the same temperature, which significantly improves the production efficiency of the sintering process. In addition, in terms of veneer loading and billet loading, the company has adopted a bulk stacking method that conforms to the company's product features of small shape and light weight after many tests, realizing heavy veneer loading, good sintering atmosphere, and high sintering yield. good effect.
By optimizing the parameters of grinding machines and other processing equipment and improving the process technology, the company has improved the consistency of product thickness to ≤0.02MM within L30MM and ≤0.04MM within L50MM, and has mastered the technology of three-phase motor magnets produced by grinding tooling. Breakthroughs have been made in technical difficulties in the industry, such as product precision and stable equipment performance, and certain innovations have been achieved in technology and equipment.
The company's magnetic tile products are developing in the direction of high efficiency, low consumables, and low energy consumption. For example, through atomic substitution and compound doping, the rare earth-free ZK-5B high-performance motor magnetic tile independently developed by the company reduces the coagulation of magnetic powder, improves the orientation effect, improves the material performance and reduces the production cost by using strong magnetic field to suppress and adding a double dispersant.
