Abstract

It is found that in the process of decarburization of complex-alloyed nickel melts nitrogen is released together with the carbon to form the CO compound. As a melt alloying increases the denitride effect decreales. The intensity of denitride process during melt decarboning favours transition of [С]+[О]=СОg reaction in bubble mode («carbon boiling process»), that achieved by preliminary introduction carbon in melt and correspending increase of nickel oxide quantity.
