REMELTING FERROCHROME-CRUSHING DUST

Abstract

This article discusses the practical implications of remelting briquettes from ferrochrome dust after crushing. The formation of corrosion-resistant electrically conductive powder (CRP) and its fractional compositions are described, shedding light on the potential applications of this research. The partially described briquetting method used is explained, along with the equipment in detail, providing valuable insights for future research and industrial applications. A literature review on lignosulfonate-based binders provides a comprehensive understanding of this aspect. The work compares the remelt of briquettes in the base and experimental periods, where in the base period, dust is remelted in bulk (in the initial dusty state) and in the experimental period, in a briquette state. The article also characterizes the weighing of charge materials and their comparison; the tables indicate the electricity costs and electrodes spent on remelting, providing practical data for industrial operations. The chemical compositions of the charge materials for remelting and technical and economic indicators (referred to as TEI from now on) are given in the tables, offering practical guidance for future research and operations. The comparison results with standard melting modes are briefly touched upon, providing a valuable benchmark for the research. In the end, the results and conclusions of the work are written, summarizing the study's practical implications.
