The deoxygenation reaction of copper liquid and molten steel in the range of 142 3 ~ 1873 K was studied by using the self-assembled Zr O 2 (Mg O) solid electrolyte electrolytic deoxidation device. The deoxidation reaction mechanism was also discussed. The results show that the oxygen content can be decreased to 0.030% and the deoxidation rate can reach 90% when the oxygen content is 0.45% after 70 min in deoxygenation. The oxygen content is 0.018% After the liquid steel is deoxidized for 20 min by this device, the oxygen content can be reduced to 0.0000% and the deoxidation rate is more than 90%. This fully demonstrates the availability of the solid oxide electrolyte electrolytic deoxygenation device.
