我国轧钢耗能约占钢铁工业耗能总量的12-15%,其中加热炉燃耗占轧钢能耗的70%以上。尤其是加热炉每年要烧油150万吨,占钢铁工业烧油总量的40%。所以,抓好加热炉节能,特别是节约燃料油,是钢铁工业节能的一个重要环节。近几年来,各轧钢企业,在加强能源管理的基础上,狠抓了加热炉的节能技术改造。截止目前,重点和地方中型企业400多座加热炉已改造1/3,这对加热炉燃耗的大幅度下降起了重大作用。1981年与1978年相比,加热炉燃耗(以原料计)由0.85×10~6千卡/吨降为0.61× China’s rolling energy consumption accounts for about 12-15% of the total energy consumption of the steel industry, of which heating furnace fuel consumption accounts for more than 70% of rolling energy consumption. In particular, the heating furnace to 1.5 million tons of oil per year, accounting for 40% of the total iron and steel industry burning oil. Therefore, good energy saving furnace, especially to save fuel oil, is an important part of energy saving in the steel industry. In recent years, all rolling enterprises, on the basis of strengthening energy management, pay close attention to the heating furnace energy-saving technological transformation. Up till now, more than 400 heating furnaces of key and local medium-sized enterprises have been transformed by 1/3, which has played a significant role in the substantial reduction of heating furnace fuel consumption. 1981 compared with 1978, heating furnace fuel consumption (raw materials) from 0.85 × 10 ~ 6 kcal / ton down to 0.61 ×
