Abstract：On the basis of the condition of one local steelmaking plant, thermodynamics analysis for the possibility of making weathering steels by direct alloying with nickel oxide in the converter was conducted.The results showed that［C］，［Si］，［Mn］and［Fe］ can reduce NiO and making weathering steels by direct alloying with nickel oxide both in the hot metal and the converter are possible. At the end point of converter (T=1960 K, w（［C］） =004%), the reducing ability of ［C］ is stronger than ［Fe］ and the yield of nickel is more than 999%. And the relative kinetics experiment was carried out. The results of kinetics experiment showed that, under the condition of hot metal (w（［C］）=3%, T=1573 K) the rate of reducing nickel oxide is very fast, which can be basically completed in 15 min.
