“七五”期间,冶金工业累计节能700万吨标煤,其中相当一部分节能效果来自工业炉窑的节能降耗。自1989年底第一次召开冶金工业炉窑节能工作会议后,这项节能工作走上了新台阶.至今,工业炉窑推广应用节能新技术进行改造的轧钢加热炉共计580多座炉次,均热炉180多坑次,共节约标煤40多万吨,完成了每年节能改造100多座炉子、节 During the “Seventh Five-Year” period, a total of 7 million tons of standard coal have been saved in the metallurgical industry. A considerable part of the energy-saving effect comes from the energy saving of industrial furnaces. Since the first metallurgical industrial kiln energy conservation conference was held in late 1989, the energy saving work has taken a new stage. To date, more than 580 furnaces have been rolled out in industrial furnaces to promote the use of new energy-saving technologies for transformation. More than 180 pit furnace pit, saving a total of more than 400,000 tons of standard coal, completed an annual energy-saving more than 100 stoves, section
