兴澄特钢主要工序电耗和能耗研究

Study on the electric power consumption and energy consumption on the main procedures of Xingcheng Special Steel

  • 摘要: 对兴澄特钢的一些主要工序: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吨钢电耗、能耗值.特炼分厂电炉炼钢年产量2002年为79.18万t,2004年为91.60万t,增长15.69%;电炉吨钢冶炼电耗由340.20kW·h·t-1降至166.30kW·h·t-1,降幅51.12%;而全流程吨钢能耗由289.51kgce·t-1上升到615.44kgce·t-1,增长1.13倍.

     

    Abstract: The data of energy and energy consumed materials on the procedures of sintering, iron-making in BF, steel-making and steel-rolling in Xingcheng Special Steel were collected, dealt with and analyzed. The en-ergy consumption and the electric power consumption per ton of products every procedure were calculated and converted into per ton of steel in the whole process. It showed that the yield of Xingcheng Special Steel increased from 791.8 thousand tons in 2002 to 916 million tons in 2004, which increased 15.69%. And the electric power consumption of EAF decreased from 340.20 to 166.30 kW·h·t-1, which is 51.12% less. And the energy consump-tion per ton of steel in the whole process increased from 289.51 to 615.44 kgce·t-1, which is 112.58% more.
