Production method of the ferritic stainless steel whose solidification organization is minute and the ferritic stainless steel which is produced because of this

摘要

Controlling the density of the alumina debris in the molten steel, when solidifying maximizing the formation effect of the validity TiN which operates as the uneven nucleation sight of ferrite and so on stage and throw Al stage and compound deoxidization stage and the alloy stage where the decarbonization reaction is done in regard to the production method of the ferritic stainless steel where the solidification organization which axial crystal ratio to improve it tries is minute and the ferritic stainless steel which is produced because of this, and, primary distinction stage and, including with secondary distinction stage and the stage which it continues casts, it becomes.
