一、前言钢铁工业为高能耗行业,其能源消耗约占全国总能耗的12%～14%,占自身生产成本的20%左右。与国外先进水平相比,我国吨钢综合能耗和主要工序能耗平均要高出10%～15%,二次能源的利用水平普遍偏低。因此,利用测量和控制技术资源,不断完善开发能源测控信息化管理系统,推进和提升节能管理水平是钢铁企业的长期任务。目前,我国钢铁工业正从单体设备和工序的节能转向企业层次的整体节
I. INTRODUCTION The steel industry is a high-energy-consuming industry whose energy consumption accounts for 12% ~ 14% of the total energy consumption of the country and accounts for about 20% of its own production cost. Compared with foreign advanced level, China’s comprehensive energy consumption per ton of steel and the main process energy consumption average higher than 10% to 15%, the secondary energy use generally low level. Therefore, the use of measurement and control technology resources, and constantly improve the development of energy measurement and control information management system to promote and enhance the level of energy-saving management of steel enterprises is the long-term task. At present, China’s steel industry is turning from the energy-saving of single equipment and processes to the corporate-level whole section
