This project aims to optimise slag design in electric arc furnace steelmaking, leading to decreased consumption of refractory, increased metal yield and efficient energy utilisation. Along with trial runs at Onesteel mini-mill, graphite/slag and refractory/slag interactions will be investigated using in-situ, a high-temperature visualisation-based facility as a function of slag composition and temperature. The effect of gas injection on slag foaming and bubble coalescence will be investigated for a range of injection conditions. The outcomes of this project are expected to be substantial to the steel industry in terms of both economic and environmental advantages.

该项目旨在优化电弧炉炼钢中的炉渣设计，从而减少耐火材料的消耗，提高金属产量并有效利用能源。随着 Onesteel 小型轧机的试运行，石墨/炉渣和耐火材料/炉渣相互作用将利用基于高温可视化的设施进行现场研究，作为炉渣成分和温度的函数。将在一系列注入条件下研究气体注入对炉渣发泡和气泡聚结的影响。该项目的成果预计将对钢铁行业带来巨大的经济和环境优势。
