Abstract
The invention discloses a magnetic ring with improved magnetic wear resistance and a preparation method thereof. By adding clay to the magnetic ring in the preparation process, the plasticity of the magnetic ring is increased and the surface hardness of the prepared magnetic ring is effectively increased, thereby improving The wear resistance of the magnetic ring, by adding trimanganese tetroxide, the prepared magnetic ring has a narrow remanence induction curve, which can be magnetized repeatedly, and the magnetism of the prepared magnetic ring is effectively increased by adding the cylinder and aluminum. The equipment can form two magnetic rings at the same time. At the same time, the design of the injection screw greatly improves the conveying efficiency of the kneaded material. After the magnetic ring is dried, the magnetic ring is sucked out by the magnetic suction plate, which effectively improves the efficiency of the entire magnetic ring processing process.
Description
technical field [0001] The invention relates to the technical field of magnetic ring preparation, in particular to a magnetic ring with improved magnetic wear resistance and a preparation method thereof. Background technique [0002] The magnetic ring is a ring-shaped magnetic conductor. The magnetic ring is an anti-interference component commonly used in electronic circuits, and it has a good suppression effect on high-frequency noise. [0003] The patent document CN201811349097.1 discloses a magnetic ring processing method. The magnetic ring processing method transports the mixed raw materials to the calcined, presses the calcined mixed raw materials into a magnetic ring green body, grinds the magnetic ring green body, and The polished green body is sintered to realize the sintering process of the magnetic ring, but the magnetic ring processing method does not improve the magnetic properties and wear resistance of the existing magnetic ring, and the process efficiency of ...
