This article presents an assessment of the possibility of using dry gas cleaning dust in the production of ferrosilicoaluminium in the form of briquettes, as well as the study of their physical and chemical properties and the analysis of alloy smelting according to the developed technologies.
The briquetting method is suitable for gas cleaning dusting, since the briquette includes a carbon-containing reducing agent, which eliminates the heat treatment of the oxidized raw materials. The composition of the briquette consisted of dust and screenings of special coke from long-flame coals. The choice of coal fines as a reducing agent is motivated by its high reactivity and relatively low ash content.
Manufactured briquettes were subjected to a number of tests to determine their physical, chemical and mechanical properties. To determine the suitability in industrial production behavior of experimental briquettes under thermal influence were compared with the standard charge for the smelting of ferrosilicoaluminium, consisting of high-ash coal, additives of quartzite and steel chips. Ken in single-phase heat treatment furnaces melting monority conducted by the traditional and proposed technologies. The results obtained by melting were compared and the design models of 250 kV∙a capacity in an industrial furnace were presented.
