SK3 high-carbon steel is a type of carbon tool steel. It is not inherently a permanent magnet material but can acquire stable magnetic properties through a specialized magnetization process, meeting the requirements of industrial applications such as magnetic bearings and positioning/adhesion systems. To magnetize SK3 steel strips, the material must first undergo quenching and tempering heat treatment to adjust its microstructure, thereby enhancing its residual magnetism and coercive force and laying the foundation for magnetization. The workpiece is then placed in a strong pulsed magnetic field, causing the magnetic domains within the steel to align in a predetermined direction. Once the external field is removed, the residual magnetism is retained, enabling the adhesive function. Since carbon steel has relatively low coercivity, the magnetization energy must be precisely matched to the workpiece dimensions to avoid insufficient magnetic force or performance degradation. Jiuju’s specialized magnetization equipment for bearing steel can precisely control magnetization parameters for SK3 material. Combined with surface magnetic field detection to verify magnetization effectiveness, it ensures uniform and consistent magnetization across batch-produced workpieces, meeting the demands of large-scale industrial bearing production.

Magnetization itself is a physical process that takes place in milliseconds; what truly slows down the overall production cycle are the manual loading, unloading, and alignment and calibration steps. In manual magnetization mode, workers must pick up and place each part individually and verify the polarity direction, which takes several seconds per part. Production capacity fluctuates significantly depending on the workers’ skill level and fatigue, and the strong magnetic field environment also poses safety hazards.
