概要
- 論文の詳細を見る
Non-metallic inclusions in electro-slag welded steels using several fluxes of the system MnO-SiO_2 or CaO-MnO-SiO_2 were investigated with X-ray diffraction method and SEM observation. Almost all inclusions were indentified as sulphide (Mn, Fe) S (or oxysulphide (Mn, Fe) (S, O)) and sulphide-silicate duplex or silicate containing sulphur complicatedly. Iron silicate and calcium ferrous sulphide (or oxysulphide) were also found though they were rare. It was concluded that all inclusions attributed to metallurgical origins by several reasons. Relations between flux constituents and species or compositions of inclusion could not be clarified.
