| Abstract: | Three important technologies of energy supplying were introduced for 150 t electric arc furnace steel-making process in Tianjin Pipe Group Co., which were hot metal charging, 2 500 m^3/h oxygen supplying and 100MVA transformer power supplying, and they could be integrated reasonably among them. Through technological transformations and production practice for more than ten years, good production progress had been made. The tapping to tapping time was 54.6 min on average and the oxygen consumption approxi- mately 42.9 m^3/t. The smelting electricity consumption was decreased to about 325 kWh/t and the transformer utilization factor had surpassed 11000 t/（MVA· a）. |
