大冶特钢是国内有代表性的电炉炼钢企业之一，本文对该企业的一些主要工序——烧结、炼铁、炼钢和轧钢的能源、物质消耗和耗能工质消耗数据进行收集、整理、分析，基于相同的统计和计算方法，得到生产每吨产品的工序电耗、能耗以及折算的全流程(全流程包括烧结、炼铁、炼钢和轧钢4道主要工序，这里轧钢工序只选择较大的连轧厂作为代表)吨钢电耗、能耗值。结果表明：第四炼钢厂2000年年产电炉钢25.45万t，2005年为87.34万t，增长了2.43倍；同期电炉工序的吨钢冶炼电耗由547 kW·h/t降至213 kW·h/t，降幅为61％；而全流程的吨钢能耗由448 kg（标煤）/t上升到684 kg（标煤）/t，增幅为53％。

Daye Special Steel Co., Ltd. is a representative company among EAF steel companies in China.The data of energy and material consumption of sintering, ironmaking, steelmaking and steelrolling at Daye Steel were analysed.The results show that at No.4 steelmaking shop,the output was increased from 254 thousand tons in 2000 to 873 thousand in 2005,with the specific electricity consumption in EAF steelmaking decreased from 547 kW·h/t to 213 kW·h/t.But the total specific energy consumption was increased from 448 kg(ce)/t to 684 kg(ce)/t.
