能源问题是我国实现四个现代化的重大问题之一。十二大确定到本世纪末实现工农业总产值翻两番,但能源只能翻一番。解决能源问题,必须贯彻执行开发和节约并重的方针。在我们重型机械工厂的电能耗量中,炼钢电弧炉占全厂耗电量40%左右,有的超过60%、就电能单耗来说,机械工厂炼钢电弧炉历年来有所降低,先进的已低于600度/t, The issue of energy is one of the major issues in our country’s realization of the four modernizations. The 12th National Congress of the Communist Party of China decided to quadruple the gross output value of industry and agriculture by the end of this century, but energy will only double. To solve the energy problem, we must implement the principle of equal emphasis on development and conservation. Among the electric energy consumption of our heavy machinery factory, the steel-making electric arc furnace accounts for about 40% of the whole plant’s power consumption and some over 60%. As far as the electric energy consumption is concerned, the mechanical factory EAF has been reduced over the years, Advanced has been below 600 degrees / t,
