Method for determining content of components in iron ore by X-ray fluorescence spectrometry

Abstract

According to the method for measuring the content of the components in the iron ore through the X-ray fluorescence spectrometry, ammonium bromide is used as a mold release agent, the mold release effect is good, the wall hanging phenomenon is remarkably reduced, and a platinum crucible needs to be repaired after being used for about 90 days under the normal condition, so that the platinum crucible is protected, serious corrosion to the platinum crucible is avoided, and the service life of the platinum crucible is prolonged. The service life of the platinum crucible is prolonged, and the maintenance cost of the platinum crucible is reduced; the X-ray fluorescence spectrophotometer can normally detect TiO2, the TiO2 does not need to be independently detected, and the detection period is shortened; according to the method, the content of elements or components in the iron ore is determined by adopting the X-ray fluorescence spectrometry, TFe, SiO2, Al2O3, CaO, MgO, S, P, TiO2 and MnO in the iron ore are determined by optimizing the material ratio, the process steps and the process parameters, and the method has relatively high precision and accuracy and is convenient, rapid and efficient.

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgical testing, in particular to a method for measuring component content in iron ore by X-ray fluorescence spectrometry. Background technique [0002] In melting sample preparation, after the iron ore sample, mixed flux, oxidizing agent, cobalt powder, and mold release agent are mixed evenly, an automatic melting furnace is used to make a glass sheet. The role of the mold release agent: 1). When the automatic melting furnace turns into a liquid, the fluidity of the sample is improved, so that the sample is mixed with other reagents; 2). After cooling and shaping into a piece, the glass piece is separated from the crucible. At present, potassium iodide is usually used as a release agent for demoulding. There are two problems: 1). When the crucible is about 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 ,th...

Problems solved by technology

At present, potassium iodide is usually used as a release agent for demoulding. There are two problems: 1). When the crucible is about 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 ,the wall hanging will be serious, each time needs to rewash thepot before use again; In less than 60 days, the platinum crucible needs to be repaired once, the price of repairing once is about 10,000 yuan, the maintenance cost is very high; 2). The use of potassium iodide as a release agent cannot detect TiO 2 , a sample needs to be divided into two inspections, resulting in a long inspection cycle
