Abstract
Изобретението се отнася до метод, при който като изходен материал се използва брикет, съдържащ железен оксид, например желязна руда или други подобни, и въглероден редуктор като въглен или други. Железният оксид се редуцира чрез нагряване, за да се получи метално желязо. В процеса на редукция се формира повърхностен слой от метално желязо, който нараства върху повърхността на брикета, а вътре в него се натрупва шлака. Редукцията продължава, докато в покривния железен слой не остане никакъв железен оксид. След това металното желязо и шлаката сенагряват допълнително и след като се разтопят, серазделят. Получава се метално желязо със сравнително висока степен на метализация. Методът е ефективен вследствие на използването на устройството. Металното желязо има висока чистота и може да се получава непрекъснато при висока производителност от железен оксид, който може да е както с високо, такаи със сравнително ниско съдържание на желязо.
