Abstract

Методът за получаване на стопено желязо се осъществява чрез осигуряване на железен окис и въглероден редуциращ агент (1), приготвяне на формован продукт от въглероден редуциращ агент и железен окис (2); получаване на твърдо редуцирано желязо от формования продукт, при което твърдото редуцирано желязо е метализирано поне 60% и има относително теглонай-малко 1,7 и съдържание на въглерод поне 50% от теоретичното количество, необходимо за редуциране на железния окис, оставащ в твърдото редуцирано желязо (3). Преди да протече практическо охлаждане, твърдото редуцирано желязо се нагрява в електродъгова топилна пещ при висока температура (4). Стопеното желязо може да бъде получено ефективно от железни руди с относително ниско съдържание на желязо, без да се причинява ерозия на огнеупорната облицовка, при висока енергийна и редукционна ефективност и при опростени процес и съоръжение.
