Utilization of Steelmaking and Hot-Rolling Mill Waste

Abstract

Based on the composition and characteristics of steelmaking dry-dedusting dust and oxide scale in hot-rolling mill, cold briquetting ores were processed by dust and oxide scale, and applied to converter vanadium recover. The research results show that, hot metal carbon oxidation rate and vanadium oxidation rate increased with the increased use of cold briquetting ores, and the TFe content of vanadium slag reduced, the consumption of iron and steel materials decreased. Not only can effectively use the steelmaking mill and hot-rolling mill waste, but also can improve the product quality of the converter vanadium recover.
