説明

Since the co-existence of a small amount of tellurium can be expected to improve the practical deoxidation of steel, three kinds of experimental examinations were carried out to eliminate the residual tellurium out of steel as the subsequent treatment. The results are<br>(1) Tellurium evaporates fairy fast out of the molten iron into Ar stream.<br>(2) Rare earth metal is the best substance to be added for the elimination of tellurium at a low oxygen potential of molten iron.<br>(3) CaF2-CaGN2 composite flux is also applicable, especially one with a composition ratio of 1:1 which has succeeded in reducing the residual concentration of tellurium to rd. 20ppm (about 90% reduction performance) during 20min treatment.
