钢铁厂是能耗最大的用户之一。我国年产100万吨的钢铁厂,每年耗电7亿度,耗动力煤20万吨,耗焦煤120万吨,平均每吨钢耗1.5吨标准煤。与世界工业发达国家差距很大。据调查钢铁厂耗电最大的是“五机一泵”,五机为:烧结抽风机、高炉鼓风机、制氧机、空压机和轧钢机、一泵就是水泵。下表是攀钢“五机”的台数和总容量:
Steel plant is one of the largest users of energy consumption. China’s annual output of 1 million tons of steel mills consumes 700 million kilowatt-hours a year, consumes 200,000 tons of thermal coal and consumes 1,200,000 tons of coking coal, averaging 1.5 tons of standard coal per ton of steel. There is a big gap between the industrialized countries in the world and the rest of the world. According to a survey of the steel plant is the largest power consumption, “five machine a pump,” five machines: sintering suction fan, blast furnace blower, oxygen machine, air compressor and rolling mill, a pump is the pump. The following table is the number of Panzhihua Iron and Steel “five machines” and the total capacity:
