Research on MRT3-BA Steel in Macro Inclusions

Abstract:

The research about the macro-inclusions of three processes: BOF→ LF→ CC, BOF→ RH→ CC and BOF→ LF→ RH→ CC, shows that: The types of inclusion are SiO2-Al2O3-CaO-TiO2-MnO, SiO2 and SiO2-Al2O3. The content of SiO2-Al2O3- CaO-TiO2-MnO in the three processes are 34.2%、23.5% and 27%; The content of SiO2 are 24.4%、47% and 27%; The content of SiO2-Al2O3 are 26.8%、17.6% and 9%. Large inclusion>300μm takes up 69.8%~85% of the total inclusion in billet in three technological processes, and the inclusion, containing K and Na, is the most; slag entrapment in mould is really serious. Considering the cleanliness and cost, the better technological process of MRT3-BA stamping steel is BOF→ RH→ CC.
