| titleOfInvention | Method of manufacturing iron-based pressurized core |
| abstract | The present invention relates to a method for producing iron-based pressurized cores for magnetic parts for use in switching power supplies and the like, which utilizes a roll-surface abrasive grains as a raw material for cores and has a relatively high permeability as well as an iron- The present invention provides a method of manufacturing a core.n n n The present invention is characterized in that a raw surface raw material powder classified into 150 to 250 占 퐉 and a roll surface polishing abrasive of 3 to 30 wt.% Of 150 占 퐉 or less classified with respect to the weight of the core to be produced are mixed and then surface treated with a coupling agent , The binder and the curing agent are added in an amount of 0.1 to 1 wt.% Based on the weight of the core to be produced, and the core is molded with a vertical pressure of 10 to 15 ton / cm 2 , And then curing the mixture for 2 hours to produce an iron-based compacted core.n n n According to the present invention, it is possible to manufacture an iron-based pressurized core having excellent magnetic properties by utilizing the surface-ground abrasive debris, so that waste resources can be effectively utilized.n n n n Iron, billet, core, roll, surface, debris, recycling |
