Abstract:The practice of increasing transformer capability to 100 MV·A of 150 t AC EAF at Tianjin Pipe Group Co.Ltd is introduced. Based on the experience of EAF operated with original 90 MV·A transformer a program of studying EAF steelmaking with transformer of higher capacity was suggested. The program included four steps: the simulation study before hot trial run,the hot trial run,the study of power schedule for actual steelmaking and the study of normal production.The results show,that secondary voltage of transformer must be measured and the impedance must be set according to the measured operation parameters.The power consumption was reduced by 5 kW·h/t and tap to tap time was reduced by 2 min after replacing 90 MV·A transformer by 100 MV·A transformer.
