Research on Micro Inclusions of SS400 Steel in Slag Washing Process

Abstract:

The variations of T[O] and [N] as well as non metallic inclusions in different working processes of two kinds of SS400 steel production process in Han Group are studied systematically by tracing experiment, systematic sampling and integrated analyzing. The following results are observed: slag washing process and traditional process can both produce qualified steel. The slag washing process has good removal effect for Al2O3 inclusion compared with the traditional process. After slag washing treatment，the content of T[O] and [N] in slab when steady-state casting are respectively 21.75×10-6 and 24.9×10-6, which are respectively 84.9% and 76.1% of the content after LF treatment. The number of the micro inclusions is 5.583 piece/mm2,which is 79.2% of the number after LF treatment.
