| Abstract: | To improve the properties of CaO based ladle slags and control rephosphorization and carry out dephosphorization of the liquid steel in ladle, the effects of Li 2O,Na 2O,K 2O and BaO on the melting point ,viscosity and dephosphorizingability of the simulated CaO based ladle slags, in which part of CaO is replaced by equal weighted additives, are studied The results show that all the four kinds of additives could decrease the melting point and viscosity of slags effectively, in which the action of Li 2O is most conspicuous; The dephosphorizing and rephosphorization controlling ability of CaO based ladle slags is enhanced remarkably by additives and a small amount of additives added to slags can control the rephosphorization of steel |
