碱性氧气炼钢（BOS）炉渣，是熔融金属元素（例如，硅、锰、铁、磷）的氧化和熔剂（如石灰、白云石）的溶解，在高质量粗钢的生产中起着至关重要的作用，尽管其在BOS容器内的行为（与金属液滴和气体的形成和反应）仍然不清楚，其回收一直具有挑战性。在此，除了对文献中报道的相关研究进行批判性综述外，还介绍了作者进行的BOS-炉渣相关研究的实例。这包括四个重要的主题：1）炉渣的形成，即，石灰在BOS炉渣中的溶解; 2）原位观察BOS炉渣的高温行为; 3）由于金属液滴-炉渣-气体反应而在BOS炉渣中的瞬态现象;以及4）从熔融BOS炉渣中回收能量和材料。本文旨在为这些研究主题提供最新的理解和新的研究思路。重点放在方法，寻求在现场探测渣的演变，并记录其物理和化学变化。
Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays a critical role in the production of high‐quality crude steel, although its behavior inside the BOS vessel (formation and reaction with metal droplets and gas) is still not clear and its recycling has always been challenging. Herein, examples of BOS‐slag‐related research conducted by the present authors are introduced, in addition to a critical review of relevant research reported in the literature. This includes four important topics: 1) slag formation, i.e., dissolution of lime in the BOS slag; 2) in situ observation of high‐temperature behavior of BOS slags; 3) transient phenomena in BOS slags due to metal droplet–slag–gas reactions; and 4) energy and material recovery from molten BOS slags. This article aims to provide state‐of‐the‐art understanding and new research ideas on these research topics. An emphasis is placed on methods that seek to in situ probe the evolution of the slag and to document its physical and chemical changes.
