In accordance with inclusion defects occurred on cold rolled sheet of 430
0C113R
409 etc. ferrite stainless steels
the effect of basicity (1. 10 ~ 5. 98) of tundish covering flux on cleanliness of steel is studied
and the change of basicity

content in tundish covering flux with basicity R = 5. 98 during casting process is analyzed. Results show that in casting process
the basicity R =5. 98 of high basicity tundish covering flux decreases from original flux R = 5. 98 to R =3. 0
the high basicity tundish covering flux has excellent ability to absorb the inclusions in steel and has low ability of transport oxygen to liquid steel
the high basicity flux can remarkably improve cleanliness of steel.
