| Abstract: |
| The affecting factors on current efficiency of pipeline magnesium electrolysis were studied by orthogonal and stability test. The results show that the factors affecting current efficiency, sequenced by influence, include MgO content, cell temperature, electric current density, negative pressure of chlorine pipe and circular flow. Reducing MgO content, cell temperature and negative pressure, and increasing circular flow and electric current density can improve current efficiency. The current efficiency of pipeline magnesium electrolysis can maintain as 78% above under the conditions including MgO≤0.1%, cell temperature of 680~695 ℃, negative pressure of ≤10Pa, circular flow of 55 t/h, and current density of 0.30 A/cm2. |
