1. Background and meaning

The non-ferrous metallurgy smelting process is affected by various sources of raw materials There are a lot of uncertainties in the influence of factors such as fluctuations in working conditions and changes in production composition. It can ensure the stability of the furnace production process and the optimization of energy consumption by using the online accurate detection of the high-temperature melt composition in the smelting process.

2, plan

Currently, the component detection in the non-ferrous metallurgy industry is mainly through a series of processes such as manual sampling-cooling-sample preparation, and then sent to the laboratory for analysis, which is an offline analysis. The inability to guide the production process in real time greatly affects production efficiency and causes energy waste.
Laser-induced breakdown spectroscopy(LIBS) online detection technology can perform real-time online qualitative and quantitative analysis of various elements, and solve the problems of traditional detection methods "offline-lag-artificialization" with "online-real-time-digitalization".
By setting up the GS-LIBS2200 high-temperature melt online testing equipment at the original offline testing and sampling location of the melt chute, real-time component testing of the molten melt is carried out, and the model parameters of the production process are calculated based on the testing data to realize the stable control of the material composition of the smelting production process. Ensure the stability and optimization of the smelting production process.
