The production process and manufacturing materials of square magnets have the following requirements:
Production process requirements:
Raw material processing: It is necessary to crush, grind, and mix the raw materials to meet the required particle size and composition requirements for manufacturing magnets.
Melting: Adding raw materials to a furnace for melting to achieve Curie temperature and complete magnetic transformation.
Ingot casting: The molten liquid is poured into ingots and subjected to cooling, processing, and other treatments to obtain the desired shape and size of magnets.
Crushing: Breaking the ingot into pieces of the required size for subsequent processing.
Grinding: Grinding the broken pieces into fine powder to meet the particle size requirements for manufacturing magnets.
Pressing: Pressing finely ground magnetic powder to produce the desired shape and size of magnetic components.
Sintering: Sintering the pressed components to achieve Curie temperature and complete magnetic transformation.
Surface treatment: Conduct surface treatment on sintered magnetic components to increase their wear resistance, corrosion resistance, and other properties.
Manufacturing material requirements:
Raw materials: The main raw materials for manufacturing square magnets are ferrite or rare earth alloys.
Ferrite: Ferrite is an oxide composed of elements such as iron, manganese, zinc, etc. It has high magnetic permeability and coercive force, and is suitable for manufacturing magnets at high frequencies and high magnetic induction strength.
Rare earth alloy: Rare earth alloy is an alloy composed of rare earth elements, with high magnetic permeability and magnetic induction strength, suitable for manufacturing magnets at low frequencies and high magnetic induction strength.
In order to ensure the quality and stability of the square magnet, the following controls need to be carried out:
Raw material control: Strictly control the quality of raw materials to ensure that their chemical composition and physical properties meet manufacturing requirements.
Melting control: Control the melting process to ensure that the raw materials are fully homogenized and reach the Curie temperature, thereby ensuring the stability of magnetic properties.
Manufacturing control: Control the manufacturing process to ensure that the manufacturing process meets the requirements, thereby ensuring product performance and quality.
Testing control: Conduct testing control on finished products to ensure that their performance meets requirements and is classified.
