| titleOfInvention | Manufacturing method of iron oxide with small quality deviation |
| abstract | The present invention relates to a method for producing iron oxide having a small quality deviation, and its purpose is to classify waste acid by pickling lines and to reduce component variation as well as powder characteristics of the obtained iron oxide by aging. It is intended to provide a very effective way.n n n The present invention for achieving the above object comprises the steps of separating and storing the waste acid discharged from the Pickling & Oiling Line (POL) and Pickling & Tanden Cold Mill (PLTCM) pickling line in a POL dedicated storage tank and a PLTCM dedicated storage tank, respectively; Aging the spent acid stored in each tank with stirring for at least 3 days at a temperature of 70-90 ° C .; And it relates to a method for producing iron oxide is characterized in that the quality deviation is characterized in that it comprises a step of roasting to produce iron oxide. |
