由西德科尔夫(Korf)财团研制的能量利用率最佳的炼钢炉(EoF),已在科尔夫财团的巴西冶金分公司建造投产了。其特点如下: (1)采用了已在许多平炉炼钢中成功使用过的埋入式吹氧管。 (2)圆筒形的炉子,结构紧凑,热量损失小。 (3)炉内一氧化碳气体能完全燃烧成二氧化碳。 (4)可用EOF炼钢炉排出的废气预热废钢。 (5)通过预热此法所使用的空气,可回收利用废气中的大量显热。 (6)装料格外灵活,可装入50％铁水和50％废钢。而废钢所需的附加热能不到0.2千兆卡/吨。风口安装在熔池下面,目的是能使熔池有 The most energy-efficient steelmaking furnace (EoF), developed by the Korf consortium, was constructed and put into production at the Corfu branch of Metco in Brazil. The features are as follows: (1) The buried lance has been used successfully in many open hearth steelmaking. (2) cylindrical furnace, compact structure, small heat loss. (3) The furnace carbon monoxide gas can be completely burned into carbon dioxide. (4) Waste gas from EOF furnace can be used to preheat scrap. (5) By preheating the air used in this method, a large amount of sensible heat in the exhaust gas can be recovered and used. (6) Extra load flexible, can be filled with 50% hot metal and 50% scrap. The additional thermal energy required for scrap is less than 0.2 gigatacre per tonne. The tuyere is installed below the puddle, the purpose is to make the puddle have
