21世纪初,我国科技工作者开姑开展系统节能在氧化铝工业中的理论和应用研究.指出氧化铝生产中的节能应注重设备、工序、车间、企业间的相互协调,实现能源和非能源同时节约.在此基础上,本文将尝试对氧化铝生产系统的层次和结构做初步的划分,并对系统节能技术在氧化铝生产中的研究现状与发展趋势做一些探讨.“,”At the beginning of the 21st century, the theory and application of systematic energy saving was studied in alumina industry by scientific and technical workers of our country. It is pointed out that the mutual coordination among equipment, process, workshop and enterprise should be taken seriously in energy saving of alumina production in order to save energy and material. Based on this, the preliminary division of the level and structure of alumina production system is made, meanwhile, the research status and development trend of systematic energy saving in alumina production are discussed in this paper.
