Abstract: According to the equation of the incomplete combustion and the empirical formula of the required total amount (CO+ H₂) which is provided for Fe₂O₃ reduced to FeO, the paper introduces a calculating formula of CO concentration controlling the reducing atmosphere with the ranges from 1000 to 1400℃. By the analysis of the thermodynamics, the reducing abilities between CO and H₂ are made by comparison in the reducing atmosphere. The paper also points out a method of CO indirect control in the reducing atmosphere containin∑ (CO+ H₂).

Keywords: calculating formula of CO, reducing atmosphere
