Abstract During cooling and permanence outside, the solidified slag involved in the refinement process taking place in the steelmaking ladles suffers attack by environmental components such as water vapor and gaseous CO2 (weathering). The reactions involved are hydration and carbonation, and as a consequence, the pulverization of the slag occurs. In the present paper, the results of a study of the degradation of a typical steelmaking ladle slag over a period of eighteen weeks (126 days) are reported. To monitor the slag evolution, several experimental techniques were used, some of them rarely employed in this context, after dividing the initial slag batch in four granulometric fractions between > 7.2 mm and

炼钢钢包炉渣​​的环境风化

摘要 在外部冷却和持久化过程中，钢包中精炼过程所涉及的固化炉渣受到水蒸气和气态 CO2 等环境成分的侵蚀（风化）。所涉及的反应是水化和碳酸化，因此，发生炉渣的粉化。在本文中，报告了对典型炼钢钢包渣在 18 周（126 天）内降解的研究结果。为了监测渣的演变，使用了几种实验技术，其中一些很少在这种情况下使用，在将初始渣批次分成大于 7.2 毫米和
