Exploration of Sinter Detection by X-ray Fluorescence Spectrometer Melt Sheet Method
The components of TFe,SiO2,CaO,MgO,Al2O3,MnO,S and P in sinter were determined.The samples were cooled into the sample box by fusing method and then transferred to MXF-2400 X-ray fluorescence spectrometer for determination.Through a variety of comparative tests,the measurement results of each group in the melt sheet method are accurate and reliable,and can he accepted.The sample was determined by X-ray fluorescence spectrometer melt sheet method instead of tablet method and titanium trichloride reduction potassium dichromate titration method to determine total iron.Under the premise of maintaining the accuracy of the results,the detection time was greatly shortened and the stability was significantly improved.After real-time determination of harmful element sulfur in sinter by developing infrared carbon sulfur meter,the material ratio in sinter was determined.The production of molten iron has a very practical guiding significance,and also avoids the pollution of the surrounding environment caused by the waste liquid containing chromium produced by the traditional chemical method in the determination of total iron.
