Research and Application of Basic Tundish Covering Flux

Abstract:

The elementary theory of functions of the basic tundish coving flux is analyzed at the beginning of this paper. Several types of the flux used in deferent steel grade include ultra-low carbon steel, low carbon steel and micro-alloyed steel. The result shows that the basic flux with CaO/SiO₂ to be 3~5 can help to control the SiO₂ be reduced by Al in steel within ±2%, and whole cleaness keeps stable with suitable component and proper process condition, marked with the T[O] content change ranged within 3ppm. But the basicity should be variable considering the productivity for different steel grade.
