1. Background and meaning

As the main raw material for iron and steel smelting, the chemical composition and physical properties of sinter directly affect the production conditions and product quality of the blast furnace. Due to the complex composition and variety of sinter raw materials, the on-line accurate detection of the composition of the sinter mixture and the analysis of the quality control indicators of the mixture can realize the intelligent batching control of the sinter mixture to achieve the purpose of guiding the operation of the blast furnace.

2, plan

The current method for detecting the composition of sinter is mainly by manually or mechanically sampling finished sinter samples and sending them to the testing room for X-ray fluorescence spectroscopy analysis. Due to the hysteresis of the test results, the sintering process conditions may have changed at this time. For example, the on-site operator mechanically adjusts in accordance with the adjustment amount of the technical regulations, which may cause more severe fluctuations in the stability of the sinter composition, which greatly affects the finished sinter The quality stability and ingredient waste.
LIBS laser-induced breakdown spectroscopy online component detection technology can perform real-time online qualitative and quantitative analysis of various elements, and solve the shortcomings of traditional detection methods "offline-lag-artificialization" with "online-real-time-digitalization".
By setting up the GS-LIBS2500 leap-type belt material composition online detection equipment above the batching conveyor belt, real-time composition detection of the blended material on the batching conveyor belt can quickly detect the composition results of various substances and compare the production process calculations based on the detection data The model parameters realize intelligent and precise batching and ensure the stability of the basicity R of the sintered ore.
