| Abstract: | High voltage frequency conversion is applied to realize the frequency conversion control of electrical arc furnace cleaning. In the flue gas control of 70 t ABB electrical arc furnace, temperature is regarded as main parameter and two systems of frequeney conversion and power frequency are designed. The speed of cleaner is modulated according to the requirements of the technique. When the power factor raise from 0. 83 to 0. 97, the cleaning system save 60% of energy and the working conditions are also improved. The application of this technique is bright in the future. |
