    • A method is provided for producing steel from iron oxide-containing raw materials. The raw materials are initially converted, in a reduction furnace by direct reduction with a reducing gas, to a substantially metallized sponge iron. The metallized sponge iron is then melted with the addition of additives and possibly fine scrap in a melting vessel filled with a metal melt. Heat and carbon monoxide-containing exhaust gases are formed in the melting vessel due to the reaction of oxygen-containing gases with carbonaceous material. The heat is utilized in part to melt the sponge iron and the exhaust gases are utilized for the direct reduction. The melt is then transferred to a further vessel where it is further processed into steel by means of suitable metallurgical measures. In the process, the entire, strongly-heated exhaust gas from the melting vessel is caused to react in a reactor with (1) carbonaceous material, and with (2) water vapor and/or carbon dioxide. After suitable conditioning, this exhaust gas is utilized for the direct reduction of the iron oxide-containing raw materials. An exhaust gas is formed in the direct reduction furnace during the direct reduction, and part of this exhaust gas is conducted through a gas processing system and combined with the conditioned exhaust gas from the melting vessel to form the reducing gas used in the direct reduction furnace.
    • 提供了从含氧化铁原料生产钢的方法。 原料通过用还原气体直接还原在还原炉中被初始转化成基本金属化的海绵铁。 然后在填充有金属熔体的熔融容器中加入金属化的海绵铁,然后加入添加剂和可能的细小废料。 由于含氧气体与含碳材料的反应,在熔化容器中形成含有一氧化碳的废气。 部分地利用热量来熔化海绵铁,并且排气用于直接还原。 然后将熔体转移到另一个容器中,其中通过合适的冶金措施进一步加工成钢。 在该过程中,使来自熔融容器的整个强烈加热的废气在反应器中与(1)碳质材料和(2)水蒸汽和/或二氧化碳反应。 在适当调节之后,该废气用于直接还原含氧化铁的原料。 在直接还原期间,在直接还原炉中形成废气,并且该废气的一部分通过气体处理系统传导并与来自熔融容器的调节废气结合,形成在直接还原炉中使用的还原气体 。
