Reasearch and Application of Basic Tundish Covering Flux in Continuous Casting Process in WISCO

Abstract:

Fundamental theory of functions of basic tundish coving flux is analyzed at the first step. Several types of the flux used in deferent steel grade include ultra-low carbon steel, low carbon steel and micro-alloyed steel are involved . 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.
