ABSTRACT

The optimal hot metal desulphurisation (HMD) slag is defined as a slag with a sufficient sulphur removal capacity and a low apparent viscosity (η_slag) which leads to low iron losses. In part I of this study, the fundamentals behind the optimal slag were discussed. In this part these fundamentals are explored by a Monte Carlo simulation, based on FactSage calculations, plant data analysis and melting point and viscosity measurements of the optimal slag. Furthermore, the applicability of knowing the optimal slag composition for an industrial HMD is discussed.

考虑铁损和脱硫能力的最佳铁水脱硫渣第二部分：评估

摘要

最佳铁水脱硫（HMD）炉渣定义为具有足够的脱硫能力和低表观粘度（η_炉渣）的_炉渣，从而导致铁损低。在本研究的第一部分中，讨论了最佳炉渣的基本原理。在这一部分中，将基于FactSage计算，工厂数据分析以及最佳炉渣的熔点和粘度测量结果，通过蒙特卡洛模拟来探索这些基础知识。此外，讨论了了解工业HMD的最佳炉渣成分的适用性。
