摘要

Ti(C,N) in BF hearth plays an important role in protecting the BF lining and prolonging the life of BE The characterization and the crystallization process of the Ti(C,N) obtained from one dead BF were clarified in the paper. It is found that the precipitated Ti(C,N) exhibits annual-ring shape features and different colors. The annual-ring shape topography is caused by the change of the C/N ratio. The precipitated Ti(C,N) is composed of one or more large grains. Ti(C,N) presents as a superstructure or mesocrystal and evolves from Ti(C,N) nanoparticles, which are self-assembled nanomaterials with highly ordered structures. Ti(C,N) deposit forms continuously with layer-by-layer grain growth because the mesocrystal has a large specific surface area. The phase interface of Ti(C,N)-Fe presents as a shape of jagged step, and the phase interface is inlaid by many random mesocrystal structures. The Ti(C,N) deposit derived from hot metal is accompanied by layer-by-layer mesocrystal structures. The results of phase transition and morphology of Ti(C,N) provide guidance for the regulation of Ti(C,N) behavior in BF hearth.
