Abstract：Abstract:, High [Al] in 38CrMoAl ( [Al]=0.7%-1.1%) is liable to cause the nozzle blockage in continuous casting process. The composition of molten steel as well as the properties of molten slag change obviously because of the slag-steel reaction, which will worsen cleanliness of steel. Based on the analysis of slag-steel reaction characteristics by thermodynamics calculation, reasonable component and control range was analyzed for the component optimization of LF refining slag and tundish powder. In order to maintain stability of mold fluxes after absorbing Al2O3, high basic and high glass phase mold fluxes were used. The industrial experiment shows that the goal of T[O]<0.0012%，[S]<0.003%, good surface and subsurface quality of blooms are achieved.
