Spectral analysis of ferrosilicoaluminium production gas cleaning dust briquette

Abstract

This article reflects the results of spectral analysis for use in production as a second product by creating a briquette of dust formed during the melting of ferrosilicoaluminium alloy. Briquettes made according to two samples were made with isothermal retention in the Tamman furnace and spectral analysis of the resulting products was carried out. As a result of the analysis, it was found that the dust contains the main silicon and aluminum oxides not in the form of kaolinite (Al₂O₃∙2SiO₂∙2H₂O), but separately in the form of SiO₂ and Al₂O₃, as well as the absence of mullite (3Al₂O₃∙2SiO₂) during heating to a temperature of 1600°C and the formation of silicon carbide SiC at once, as well as a total of 43.73% carbide. As a result, raw materials were obtained that optimize the electric model of the melting process, solving environmental and economic problems with the return to production of the left dust as briquette waste.
