摘    要：介绍了钢铁企业技术气体系统及其特点,并对空分系统主要生产流程进行了节能分析,指出了钢铁企业技术气体系统节能控制的方向,阐述了钢铁企业主要耗气单元技术气体消耗特性,对输送和缓冲设备的重要性也做了相关说明。文中以某大型钢铁企业为背景,把氧气作为技术气体的首要调控目标,基于对技术气体用户和空分设备特性的分析,结合设备操作规范,建立了氧气调配模型,并给出部分仿真结果。仿真结果与实际生产值非常接近,为生产调度和节能控制提供了强有力的参考数据。

Abstract: To discuss the characteristics of the technical gas systems in iron and steel production processes,aiming to reduce energy consumption for main production processes of ASU(Air Supply Unit).The gas consumption characteristics and the functions of primary units and equipment,including transmit pipes,storage etc.,in the gas systems are analysed and the principles conducive to energy saving for the gas systems in iron and steel production are proposed.A computational example is given in this paper,which simulates oxygen supply system in a large iron and steel company with the oxygen allocation model that is created on the basis of the analysis and principles mentioned previously.The example shows that the computed results are very close to the actual values of the corresponding oxygen consumptions and hence can be used as sensible reference to gas dispatching and energy saving control.
