APPARATUS AND METHOD OF ANALYZING FEO OF IRON ORE FROM MAGNETIC PROPERTIES

摘要

The present invention relates to an apparatus and method for analyzing the FeO content in the sintered ore as a blast furnace raw material using magnetic properties, in the apparatus for analyzing the FeO component using magnetism, by providing a temperature measuring means and a temperature control means SUMMARY OF THE INVENTION An object of the present invention is to provide an analysis device of iron oxide components and a method for improving accuracy and reproducibility by excluding temperature dependence of the analysis device through temperature compensation.;The present invention provides a device for analyzing the FeO content in the iron ore in the form of powder using magnetic properties, the filling unit 21 is configured to be filled with a powder sample put into the sample container; A measurement coil sensor 22 configured to form a central portion so that the sample container is inserted, and a resonant coil of an oscillator is wound outside of the central portion of the sample vessel; A temperature controller 30 configured to adjust the temperature of the measurement coil sensor; An oscillator 24 for oscillating a frequency by receiving a magnetic signal output from the measuring coil sensor; A frequency calculator 25 that calculates a difference between the oscillation frequency and the reference frequency; It includes a computer 26 for obtaining the correlation between the difference between the oscillation frequency and the reference frequency at various temperatures of the measuring coil sensor and the temperature, and the correlation between the magnetic index difference and the FeO content at room temperature. An apparatus for analyzing FeO components in iron ore using magnetic properties and methods for analyzing FeO components using the same are provided.
