| titleOfInvention | Manufacturing method of ferrite magnet raw material using mill scale |
| abstract | The present invention is to provide a method for producing a ferrite magnet raw material which can lower the production cost while maintaining the original function of the magnet by grinding and oxidizing the mill scale, which is inexpensive and easy to obtain generated during the steel manufacturing process.n n n Method for producing a ferrite magnet raw material using the mill scale of the present invention comprises the steps of removing this material from the mill scale having a particle size of 20mm or less to obtain a pure mill scale; Taking a predetermined amount of the pure mill scale and dry grinding first to adjust the particle size to 5 μm or less, preferably 3 μm or less; Roasting the mill scale milled powder within a temperature range of about 600 to 800 ° C .; Cooling the roasted portion to a temperature of about 70 ° C .; And dry grinding the roasted powder in a second step to adjust the particle size to 3 μm or less. |
