神户制钢有限公司及米德莱克斯直接还原公司最近开发一种铁水生产流程,将炼铁过程从几小时缩短到几分钟。总部在日本东京的神户制钢公司及大本营设在美国北卡罗来纳州查洛托的米德莱克斯神户子公司希望在五年之内使这一工艺达到商业化。采用此炼铁法时,将粉铁矿及煤粉制的球团矿加热到1300～1500℃。该工艺用天然气取代焦炭,作铁矿还原剂。据神户制钢公司报道,用新发明的这种流程,铁矿能在6～10分钟内还原,而在用传统的高炉时则需6～8小时。据称,因为铁生产出来时呈熔液状,故可使下一道炼钢生产得到相应的节约,同时还可将铁水冷却成铁
Kobe Steel and Midrand Direct Reduction recently developed a hot metal production process to reduce the ironmaking process from hours to minutes. Kobe Steel, headquartered in Tokyo, Japan, and Midrand, a subsidiary of the parent company located in Chatuto, North Carolina, USA, look forward to commercializing the process within five years. When using this ironmaking method, the iron ore and pulverized coal pellets are heated to 1300-1500 ℃. The process uses natural gas instead of coke, iron ore reductant. According to reports from Kobe Steel, using the process of the new invention, the iron ore can be reduced within 6 to 10 minutes, whereas it takes 6 to 8 hours when using a conventional blast furnace. Allegedly, because the iron was produced when the melt-like, it can make the next steel-making production of the corresponding savings, but also the molten iron can be cooled into iron
