Abstract
1. Способ преобразования мелкодисперсного губчатого железа низкой плотности в агломераты высокой плотности с увеличенным содержанием металлического железа, пригодные для использования в качестве шихты для производства стали, который включает в себя следующие стадии: ! подача мелкодисперсного материала в факел кислородно-топливной горелки, имеющей напряженность горения, обеспечивающую полное расплавление мелкодисперсного материала, где горелка вырабатывает мощность Р по меньшей мере равную Р=kmin·θ (кВт), где kmin составляет по меньшей мере 1500 кВт·с/кг и θ (кг/с) представляет собой массовый расход вводимого мелкодисперсного материала, таким образом позволяя осуществить разделение металлосодержащего мелкодисперсного материала на металлическую и окисную части; ! разделение двух фаз на жидкий шлак и жидкое железо в соответствующей печи или камере; и ! преобразование жидкого железа в агломераты высокой плотности. ! 2. Способ по п.1, отличающийся тем, что содержит дополнительную стадию обработки жидкого шлака для последующего использования. ! 3. Способ по п.1 или 2, отличающийся тем, что жидкое железо превращают в агломераты высокой плотности посредством разделения выходящего потока жидкого железа на капли подходящего размера и последующего охлаждения этих капель в охлаждающей среде. ! 4. Способ по п.3, отличающийся тем, что по меньшей мере 90% полученных кусков высокой плотности имеют размер от 10 до 40 мм. ! 5. Способ по п.1, отличающийся тем, что мелкодисперсный материал имеет диаметр меньше, чем приблизительно 10 мм, и предпочтительно меньше, чем 6 мм. ! 6. Способ по п.1, отличающийся тем, что мелкодисперсный материал является п1. A method of converting finely divided low-density sponge iron into high-density agglomerates with an increased content of metallic iron, suitable for use as a charge for steel production, which includes the following steps:! the supply of finely dispersed material into the flame of an oxygen-fuel burner having a burning intensity providing complete melting of the finely dispersed material, where the burner generates a power P of at least equal to P = kmin · θ (kW), where kmin is at least 1500 kW · s / kg and θ (kg / s) represents the mass flow rate of the finely divided material introduced, thereby allowing the separation of the metal-containing finely divided material into metal and oxide parts; ! separation of the two phases into liquid slag and liquid iron in an appropriate furnace or chamber; and! conversion of liquid iron into high density agglomerates. ! 2. The method according to claim 1, characterized in that it contains an additional stage of processing liquid slag for subsequent use. ! 3. The method according to claim 1 or 2, characterized in that the liquid iron is converted into high density agglomerates by separating the output liquid iron stream into droplets of a suitable size and subsequent cooling of these drops in a cooling medium. ! 4. The method according to claim 3, characterized in that at least 90% of the obtained pieces of high density have a size of from 10 to 40 mm ! 5. The method according to claim 1, characterized in that the finely dispersed material has a diameter of less than about 10 mm, and preferably less than 6 mm ! 6. The method according to claim 1, characterized in that the finely divided material is p
