1.前言 1973年秋发生石油危机,日本的经济便进入了低速发展和注重节约能源的时代。因此,向来以大量生产为前提的以高生产率为标志的均热炉操作,也不得不迅速地向节能方向转变。日本钢管公司福山钢铁厂1974年以来,为降低均热炉燃料单耗,正式开展了竞赛,由于有效运用了“钢锭潜热”,成功地大幅度降低了燃料单位消耗,并建立了能 1. Foreword In the oil crisis of the autumn of 1973, Japan’s economy entered a period of slow development and energy conservation. Therefore, the soaking furnace operation, which has always been characterized by high productivity on the precondition of mass production, has also had to rapidly shift to energy saving. The Japanese steel company Fukuyama Steel Works formally started a race to reduce unit consumption of soaking furnaces since 1974. The effective use of “ingot latent heat” has succeeded in drastically reducing fuel unit consumption and establishing a
