钢铁工业是我国最耗费能源的工业部门之一,它消耗的能源约占全国总消耗的12～13%,轧钢生产的能耗在钢铁工业中仅次于炼铁,占钢铁企业总能耗的13～15%。在我国轧钢生产能耗中,燃料消耗约70～75%,电力消耗约20～25%,其它能耗约5%。而在一些钢铁生产技术发达的国家,由于机械化水平高,电力消耗超过30%,燃料
The steel industry is one of the most energy-consuming industrial sectors in China. It consumes about 12-13% of the country’s total energy consumption. The energy consumption of rolled steel production is second only to ironmaking in the steel industry, accounting for the total energy consumption of the steelmaking industry 13 ~ 15%. In China’s steel production energy consumption, fuel consumption of about 70 to 75%, electricity consumption of about 20 to 25%, other energy consumption of about 5%. In some countries where the steel production technology is developed, due to the high level of mechanization and the electricity consumption of over 30%, the fuel
