节能技术大体可分为两个方面:一是节能硬技术,二是节能软技术。几年来,在冶金企业投入大量硬技术(降低单体设备能源消耗的各项技术措施)的同时,以研究冶金企业宏观节能为任务的冶金节能软件科学也有了一定的进展。尤其在钢铁工业,从企业节能指标到系统工程分析,进行了大量的工作,但就其研究之范畴和欲达到之目标而言,节能软科学的工作尚处于刚刚起步阶段,还没有一套完整的以企 Energy-saving technologies can be roughly divided into two aspects: First, energy-saving hard technology, and second, energy-saving soft technology. In the past few years, metallurgical enterprises have invested a large amount of hard technology (to reduce energy consumption per unit of technical measures), while the metallurgical enterprises to study the macro-energy-saving metallurgical energy-saving software science has made some progress. In particular, in the steel industry, a great deal of work has been done on energy efficiency indicators and systematic engineering analysis. However, in terms of its research scope and objectives to be achieved, energy-saving and soft science work is still in its infancy and has not yet completed a complete set To enterprises
