Abstract
1. Способ получения гранулированного металла, включающий стадии, на которых:подают агломераты, содержащие оксид металла и углеродсодержащий восстановитель, на под восстановительной плавильной печи типа печи с подвижным подом;нагревают агломераты для восстановления и расплавления оксида металла;охлаждают гранулированный металл, полученный на указанной стадии нагревания; ивыгружают охлажденный гранулированный металл из печи для дальнейшего использования,в котором агломераты, имеющие средний диаметр не менее 17,5 мм, подают на под печи, когда агломераты нагревают при плотности распределения на поде печи не ниже 0,5.2. Способ по п.1, в котором углеродсодержащий материал распределяют на поде печи, и затем на углеродсодержащий материал подают агломераты с образованием одиночного слоя.3. Способ по п. 1 или 2, в котором в качестве оксида металла используют оксид железа.4. Способ по п.1, в котором в качестве восстановительной плавильной печи типа печи с подвижным подом применяют печь с вращающимся подом.5. Способ по п.1, в котором в качестве оксида металла используют пыль сталеплавильного производства.6. Способ по п.1, в котором восстановительная плавильная печь типа печи с подвижным подом включает зону выше по потоку, имеющую температуру, установленную на уровне от 1300°С до 1450°С, и зону ниже по потоку, имеющую температуру, установленную на уровне от 1400°С до 1550°С.7. Способ по п.6, в котором зону ниже по потоку регулируют так, что она имеет температуру, более высокую, чем температура зоны выше по потоку в восстановительной плавильной печи типа печи с подвижным подом.1. A method of producing a granular metal, including the stages at which: agglomerates containing a metal oxide and a carbon-containing reductant are fed to the underneath of a reduction melting furnace such as a moving hearth furnace; the agglomerates are heated to reduce and melt the metal oxide; the granular metal obtained on the specified heating stage; and the cooled granular metal is unloaded from the furnace for further use, in which agglomerates having an average diameter of at least 17.5 mm are fed to the hearth of the furnace, when the agglomerates are heated at a density of distribution on the hearth of the furnace not lower than 0.5. The method of claim 1, wherein the carbonaceous material is distributed on the hearth of the furnace, and then agglomerates are fed to the carbonaceous material to form a single layer. The method according to claim 1 or 2, in which iron oxide is used as the metal oxide. The method of claim 1, wherein a rotary hearth furnace is used as the moving hearth-type reduction melting furnace. The method according to claim 1, wherein the metal oxide is steelmaking dust. The method of claim 1, wherein the moving hearth-type reducing melting furnace includes an upstream zone having a temperature set at 1300 ° C to 1450 ° C and a downstream zone having a temperature set at 1400 ° C to 1550 ° C. 7. The method of claim 6, wherein the downstream zone is controlled to be at a temperature higher than the temperature of the upstream zone in a moving hearth type reduction melting furnace.
