| Abstract: | The effects of basicity (R) and the (FeO+MnO) content of the refining slag on the deoxidation of A36 and 45A steels were investigated during the refining process, and the influences of basicity (R) and the (FeO) content of the slag on desulfurization were also analyzed. The results show that the desulfurization efficiencies are increased to 61.3% and 64.3%, respectively. In addition, the changes of[P],[H], and[N] contents were studied. And the results show that the average removal rate of inclusions is 70.27%, and the maximum is 85.62%. |
