湖南素称“有色金属之乡”,实际上是重有色金属之乡。据1991年统计,重有色金属的产量占十种常用有色金属产量的87％,工业产值占长沙公司总产值的56％,实现利税占60％,能耗占25％,1991年节能量占50％。因此,重有色金属冶炼(简称重冶)的节能对湖南有色工业节能的全局具有决定性的意义。
Hunan, known as “hometown of nonferrous metals”, is actually a hometown of non-ferrous metals. According to the statistics of 1991, the output of heavy non-ferrous metals accounts for 87% of the output of ten commonly used non-ferrous metals, the industrial output accounts for 56% of the total output of Changsha, profits and taxes account for 60%, energy consumption accounts for 25% and energy saving accounts for 50% %. Therefore, the heavy non-ferrous metal smelting (referred to as heavy smelter) of energy-saving Hunan non-ferrous industrial energy-saving overall decisive significance.
