Abstract
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 while 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. This paper introduces BOS slag-related research examples carried out by the present authors, in addition to critical review of relevant research reported in 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 materials recovery from molten BOS slags. The paper aims to provide the state-of-the-art understanding and new research ideas in these research topics. An emphasis is placed on methods which seek to in-situ probe the evolution of the slag and to document its physical and chemical changes.
