Abstract
The rate of nitrogen removal from liquid iron containing oxygen has beenstudied by blowing Argas onto the inductively stirred liquid iron at I600°C.
At constant oxygen content, the rate of nitrogen removal is proportional tothe second power of the concentration of nitrogen in liquid iron. The rate is retarded markedly with increasing oxygen content. The rate constant κ(cm/wt%. sec) is inversely proportional to the concentration of oxygen contents ([%O]>0.01%), but at lower contents of oxygen the rate constant tends to approach a con-stant value.
It is shown that the removal of nitrogen is controlled by the chemical reaction rate. The results are
