Claims (3)

1. Способ брикетирования железосодержащих отходов в виде окалина для плавки, включающий смешивание предварительно подготовленной обычной и/или замасленной окалины с измельченным углеродсодержащим материалом и связующим, включающим кремнесодержащий материал и карбонат щелочного металла, обработку полученной смеси отвердителем, включающим водный раствор жидкого стекла, прессование и последующую сушку, отличающийся тем, что связующее содержит в качестве кремнесодержащего материала керамзит и дополнительно гидрокарбонат щелочного металла, отвердитель дополнительно содержит кремнефтористый натрий и наполнитель.1. A method of briquetting iron-containing waste in the form of scale for smelting, comprising mixing pre-prepared conventional and / or oily scale with crushed carbon-containing material and a binder, including silicon-containing material and alkali metal carbonate, processing the resulting mixture with a hardener, including an aqueous solution of liquid glass, pressing and subsequent drying, characterized in that the binder contains as a silicon-containing material expanded clay and additionally alkaline bicarbonate talla, hardener additionally contains sodium silicofluoride and filler. 2. Способ по п.1, отличающийся тем, что замасленную окалину предварительно обрабатывают силикатно-известковым раствором, содержащим известь в количестве 0,5-2,5 мас.% на 1 мас.% масла, которую добавляют к водному раствору жидкого стекла плотностью 1100-1150 кг/м3, при их соотношении 1:2-1:3, с последующим гранулированием и сушкой при температуре от 200 до 250°С.2. The method according to claim 1, characterized in that the oily scale is pre-treated with a silicate-lime solution containing lime in an amount of 0.5-2.5 wt.% Per 1 wt.% Oil, which is added to an aqueous solution of water glass with a density 1100-1150 kg / m 3 , with a ratio of 1: 2-1: 3, followed by granulation and drying at a temperature of 200 to 250 ° C. 3. Способ по п.1, отличающийся тем, что в качестве наполнителя используют кислый пылевидный минерал, в частности керамзитовую пыль.3. The method according to claim 1, characterized in that the filler is an acidic pulverulent mineral, in particular expanded clay dust.
