Investigation of Nickel Oxide Used for Alloying in BOF Steelmaking

Direct alloying of nickel oxide in a hot simulator of LD converter was investigated in laboratory. Reduction rate of nickel oxide in steelmaking process was analyzed with the test results. Under the condition of lower slag viscosity, the reduction rate of NiO increases and the Ni yield rises. When the slag viscosity is higher, a lot of metal particles with higher Ni content are contained in the slag so as to decrease the Ni yield.
