Abstract
1. Способ получения комплексных синтетических флюсов для металлургических процессов выплавки чугуна и стали, включающий смешивание фторуглеродсодержащих отходов электролитического производства алюминия, добавок и воды, отличающийся тем, что в качестве компонентов шихты используют дробленые и/или сортированные фторуглеродистые отходы производства алюминия, например отработанную углеродистую футеровку электролизеров, пыли и шламы газоочистных и аспирационных устройств и др., известь и воду, которые смешивают при следующем содержании компонентов, мас.%:фторуглеродистые отходы 50-90известь 4-20вода 6-302. Способ по п.1, отличающийся тем, что используют известьсодержащие отходы крупностью 0,01-0,2 мм с содержанием СаО60-96%.3. Способ по п.1, отличающийся тем, что для получения кусковых синтетических флюсов кусковые фторуглеродистые отходы дробят и сортируют с получением фракции 5-100 мм, известь смешивают с водой с получением известковой суспензии, фторуглеродистые отходы смешивают с полученной известковой суспензией в течение 0,5-1 мин.4. Способ по п.1, отличающийся тем, что для получения брикетированных синтетических флюсов мелкую фракцию фторуглеродистых отходов крупностью 0,1-5,0 мм смешивают с водой, полученную влажную шихту смешивают с известью в течение 7-15 мин, выдерживают на воздухе в течение 30-90 мин и брикетируют.1. A method of obtaining complex synthetic fluxes for metallurgical processes for smelting iron and steel, including mixing fluorocarbon-containing wastes of electrolytic aluminum production, additives and water, characterized in that crushed and / or sorted fluorocarbon wastes from aluminum production are used as charge components, for example, spent carbon lining electrolyzers, dust and sludge from gas cleaning and aspiration devices, etc., lime and water, which are mixed with the following content of components, wt%: fluorocarbon waste 50-90 lime 4-20 water 6-302. The method according to claim 1, characterized in that lime-containing waste with a particle size of 0.01-0.2 mm with a CaO content of 60-96% is used. The method according to claim 1, characterized in that to obtain lumpy synthetic fluxes, lumpy fluorocarbon waste is crushed and sorted to obtain a fraction of 5-100 mm, lime is mixed with water to obtain a lime suspension, fluorocarbon waste is mixed with the resulting lime suspension for 0.5 -1 min 4. The method according to claim 1, characterized in that to obtain briquetted synthetic fluxes, a fine fraction of fluorocarbon waste with a particle size of 0.1-5.0 mm is mixed with water, the resulting wet mixture is mixed with lime for 7-15 minutes, kept in air for 30-90 min and briquetted.
