  Scrap to Steel: The 5-Step Steel Recycling Process

  20231017 · Coal or coke is injected into the slag layer later in the heating operation, which reacts with the iron oxide, causing the slag to foam, increasing the furnace’s thermal efficiency, and forming metallic iron. The slag creates an envelope on the molten scrap, providing insulation to prevent the content from cooling and solidifying.

  Ladle-Furnace-Slag Reprocessing at Evraz Nizhnii Tagil Iron …

  2020924 · Ladle furnaces at Evraz Nizhnii Tagil Iron and Steel Works OJSC produce over 90,000 metric tons of slag per year. As this slag cools, it turns into a fine-grained powder; if the powder cannot be sold, it is temporarily stored until it can be disposed of [1]. We have considered producing easily used flux sinter from the slag generated during …

  Slag: From By-product to Valuable Construction Material

  2014729 · Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.
