Provided are a method for manufacturing high-density reduced iron and a device therefor, which are capable of uniformly cooling block reduced iron without requiring a large-scale briquette machine, maintaining a desired metallization rate of the entire product, and reducing the deterioration of strength. Specifically provided is a device for manufacturing high-density reduced iron from one piece of block reduced iron (R) obtained by a direct reduction iron-making process, the device characterized by being provided with a pressurizing unit (2) which pressurizes the block reduced iron under high temperature to increase the density, a guiding unit (5) which guides the block reduced iron into the pressurizing unit, pressing parts (2a, 2b) which are provided in the pressurizing unit, can sandwich the block reduced iron from both sides facing each other and substantially envelop the block reduced iron, and pressurizes the block reduced iron under high temperature, and a cooling unit (4) which cools the high-density reduced iron that has increased density by being compressed by the pressing parts. |
