Claims (6)

1. Печь с вращающимся подом для получения восстановленного металла посредством нагрева и восстановления углеродсодержащих материалов, состоящих из материала, содержащего оксид металла, и углеродистого восстановителя, содержащая под для загрузки на него углеродистых термообработанных материалов, и колпак, покрывающий весь под сверху, причем верхние части боковых концов пода перекрыты нижним концом боковой стены колпака и в нижнем конце боковой стены предусмотрено охлаждающее средство.1. A rotary hearth furnace for producing a reduced metal by heating and reducing carbon-containing materials, consisting of a material containing metal oxide, and a carbon reducing agent, containing a carbon heat-treated material underneath for loading onto it, and a cap covering the entire underneath, with the upper parts the lateral ends of the hearth are covered by the lower end of the side wall of the hood and a cooling means is provided at the lower end of the side wall. 2. Печь по п.1, отличающаяся тем, что вертикальное сечение, включающее ось вращения печи с вращающимся подом, имеет комбинацию 6 и L, одновременно удовлетворяющую следующим уравнениям: уравнение 1: L·tanθ≥30, уравнение 2: L≥0,16θ2-2,44θ+92, где θ(°) - минимальный угол уклона, открывающий по меньшей мере часть бокового конца пода, если смотреть на боковой конец пода вниз от ведущего конца на центральной стороне пода в нижнем конце боковой стены, и L (мм) - горизонтальная длина от ведущего конца до положения на боковом конце, дающего минимальный угол уклона.2. The furnace according to claim 1, characterized in that the vertical section including the axis of rotation of the rotary hearth furnace has a combination of 6 and L, simultaneously satisfying the following equations: equation 1: L · tanθ≥30, equation 2: L≥0, 16θ 2 -2.44θ + 92, where θ (°) is the minimum slope angle opening at least part of the lateral end of the hearth when looking at the side end of the hearth down from the leading end on the central side of the hearth at the lower end of the side wall, and L (mm) is the horizontal length from the leading end to the position at the lateral end giving the minimum slope angle. 3. Печь по п.2, отличающаяся тем, что в уравнении 2L≥0,16θ2-2,44θ+92 заменено L≥0,19θ2-2,44θ+100.3. Furnace according to claim 2, characterized in that in Equation 2 2L≥0,16θ -2,44θ + 92 replaced L≥0,19θ 2 -2,44θ + 100. 4. Печь по любому из пп.1-3, отличающаяся тем, что боковой конец имеет наклонную поверхность с возрастающим наклоном в направлении бокового ведущего конца напротив центральной стороны пода.4. A furnace according to any one of claims 1 to 3, characterized in that the lateral end has an inclined surface with an increasing inclination in the direction of the lateral leading end opposite the central side of the hearth. 5. Печь по любому из пп.1-4, отличающаяся тем, что боковой конец выполнен из обожженного литого огнеупора или формованного огнеупора.5. A furnace according to any one of claims 1 to 4, characterized in that the lateral end is made of calcined cast refractory or molded refractory. 6. Способ получения восстановленного металла посредством нагрева и восстановления углеродсодержащих материалов, состоящих из материала, содержащего оксид металла, и углеродистого восстановителя, отличающийся тем, что загружают углеродистые термообработанные материалы на под печи с вращающимся подом для получения восстановления металла по пп.1-5 и нагревают и восстанавливают углеродсодержащие материалы.6. A method of producing a reduced metal by heating and reducing carbon-containing materials consisting of a material containing a metal oxide and a carbon reducing agent, characterized in that the carbon heat-treated materials are loaded on under a rotary hearth furnace to obtain metal reduction according to claims 1-5 and carbon-containing materials are heated and reduced.
