钢铁工业是耗能大户,约占全国总能耗12％左右,因此节约钢铁工业能耗是重要的。我国轧钢生产能耗约占钢铁企业中总能耗的13～14％。据对部属重点企业轧钢工序能耗统计分析以及对上海和天津地区轧钢厂实际调查表明:我国轧钢工序能耗高,节能的潜力很大。 1.我国轧钢生产能耗情况 The steel industry is a major energy consumer, accounting for about 12% of the country’s total energy consumption, so saving the energy consumption of the steel industry is important. China’s steel production accounts for about 13 ~ 14% of the total energy consumption of steel enterprises. According to statistical analysis of the energy consumption of rolling mill processes of the key enterprises of the subordinate enterprises and the actual investigation of the rolling mills in Shanghai and Tianjin, the results show that the energy consumption of rolling process in our country is high and the potential for energy saving is great. 1.
