| 摘 要： | 在功能可靠度和时产率可靠性评价指标的基础上,结合钢铁生产过程系统能源消耗状况的分析,建立了能耗可靠性评价方法,提出了能耗可靠度、工序能效比及相近度等评价指标体系来描述钢铁生产过程系统的能耗可靠性.运用贡献指数的概念定量分析了后两者对能耗可靠度的影响,并应用于国内某特殊钢厂电弧炉生产过程单元.结果表明:该电弧炉工序的能耗可靠度由2008年的0.64提高到2009年的0.72.另外,还分析了该厂2006—2009年电炉工序能耗可靠度变化的主要原因.

| Abstract: | Based on the reliability evaluating indicators of functional reliability and capability utilization,in combination with studies on the energy consumption states of steel manufacturing process systems,a new assessment system of energy reliability,process energy efficiency ratio and similar degree was established to describe the level of energy consumption reliability.The concept of contribution index was used to quantitatively analyze the influence of the two latter indicators on the energy reliability.Finally,the new assessment index was also applied to evaluating the energy consumption reliability of an EAF special steel plant.The evaluating result shows that the energy consumption reliability increases from 0.64 in the year 2008 to 0.72 in the year 2009;meanwhile,main reasons for the change of energy consumption reliability in the period of 2006 to 2009 were also discussed. |
