Optimization of Power Input for Steelmaking Process in High Impedance EAF

摘要

According to the electrical operation and Steelmaking process theory of EAF, optimized power input procedure of 70t high impedance EAF In Nanjinng Iron and Steel Corp.,Ltd. was studied. We proposed investigation method, process and result for use of power supply of high impedance EAF ,and put the optimized power-supply curve to EAF Steelmaking practice, and electrical operation was improved, economizing 25kwh per ton, reducing 3min on-power.
