Method for accelerating separation of granular metallic iron from slag |
摘要 |
The present invention is intended to provide a method for accelerating separation of granular metallic iron as an objective product and slag as a by-product when the granular metallic iron is produced with reduction melting of raw-material agglomerates that contain an iron-oxide containing material and a carbonous reducing agent, thereby producing metallic iron of a high iron grade in which slag is satisfactorily separated and removed. The present invention resides in a method for accelerating separation of granular metallic iron and slag, the method being employed to produce the granular metallic iron with reduction melting of raw-material agglomerates that contain an iron-oxide containing material and a carbonous reducing agent, wherein a mixed solid of the granular metallic iron produced with the reduction melting and the slag produced as a by-product are quickly cooled to accelerate separation of the granular metallic iron and the by-product slag from each other.
