摘要
Abstract
For researching the energy saving mechanism of 168 kA new type cathode aluminum reduction cell, the thermal field, electromagnetic field, flow field of liquid metal were simulated and the surface oscillation of liquid metal in the new type cathode aluminum reduction cell was measured by a dynamic detecting system on the surface oscillation of liquid metal which was designed by the authors. The results showed that the cathode convex in the new type cathode aluminum reduction cell could reduce the velocity of liquid metal and could weaken the surface oscillation of liquid metal. The X velocity and Y velocity of liquid metal in the new type cathode aluminum reduction cell were lower than that in the traditional cathode aluminum reduction cell. The polar distance of the new type cathode aluminum reduction cell was 3. 8 cm. It was lcm lower than that of the traditional cathode aluminum reduction cell. The voltage drop of electrolyte in the new type cathode aluminum reduction cell was 380 mV lower than the voltage drop of electrolyte in the traditional cathode aluminum reduction cell. The energy utilization of the new type cathode aluminum reduction cell was 5% greater than the energy utilization of the traditional cathode aluminum reduction cell.关键词
