Abstract

The invention relates to a method for measuring chemical components in molten iron of a blast furnace by using an X-ray fluorescence spectroscopic analysis method, and belongs to the technical field of metallurgical chemical analysis tests. The technical solution is: including the following process steps: the blast furnace molten iron sample is determined by ICP-AES analysis method and infrared absorption method for its chemical composition, and several samples are determined as standard samples. The ray fluorescence spectrometer scans and draws the working curve, and calculates the content of the chemical components by measuring the intensity of the sample. The positive effects of the present invention are: scientificity, advancement, applicability, generalizability, short analysis time, high accuracy, good repeatability, no pollution, etc. The verification of correctness shows that the method has extremely high Accuracy and Precision.

Description

technical field [0001] The invention relates to a method for measuring chemical components in molten iron of a blast furnace by using an X-ray fluorescence spectroscopic analysis method, and belongs to the technical field of metallurgical chemical analysis tests. Background technique [0002] In iron and steel enterprises, the molten iron smelted in the blast furnace is not only the product of the blast furnace, but also the main raw material for downstream steelmaking. Its quality directly affects the steelmaking process and the final steel quality. The content of chemical components is very important. The traditional chemical analysis method is complicated to operate, can only analyze element by element, has many links, takes a long time, is difficult to operate, consumes a lot of reagents, and has poor repeatability, which is not conducive to guiding production and cannot meet the needs of fast-paced production. Contents of the invention [0003] The object of the pres...
