[英刊《钢时代》报道]Zia冶金工艺公司(ZMP)称,他们已开发出一种能直接将铁矿石或含铁冶金废料转化成钢的炼钢新工艺,并已取得专利。这一工艺用一种专利设计的转底炉将含铁原料与煤或其它形式的碳混合造球后形成含碳的直接还原铁(DRI)。DRI从转底炉直接热装入Zia万能炉,熔融并精炼成优质钢。这种低碳钢经合金化后可生产成任何需要的 [British edition “Steel Times”] Zia Metallurgical Process Company (ZMP) said it has developed and patented a new steel-making process that converts iron ore or ferrous metallurgical waste directly into steel. This process uses a patented rotary hearth furnace to mix iron-containing raw materials with coal or other forms of carbon to form carbon-containing direct reduced iron (DRI). DRI is directly hot-loaded into a Zia universal furnace from a rotary hearth furnace, which is melted and refined into high quality steel. This low-carbon steel can be produced after alloying needs
