METHOD FOR DENSIFYING ALUMINUM BRIQUETTES

摘要

The invention relates to a process to minimize metallic aluminum fines loss to parasitic reactions during their introduction into the tap stream of molten steel from Basic Oxygen Furnaces or Electric Arc Furnaces in the ladle, or at the secondary steelmaking vessel, by premixing oxide-free steel or iron fines, prior to briquetting, increasing the apparent density of the aluminum-containing briquette thereby decreasing its flotation into the highly oxidized slag and minimizing the aluminum losses and increasing predictability in the molten steel properties.
