【摘要】 2003年中国的生铁产量超过2亿 t,作为炼铁原料的国产铁精矿和进口铁矿几乎各占一半;国产铁精矿是细粒度的磁选精矿,进口铁矿则以粉状赤铁矿为主。如何合理配矿,成为当前必须认真研究的课题。回顾了我国炼铁工作者贯彻“精料”方针取得的成就,并就国内外铁矿资源的状况、特点及合理配矿进行探讨。更多还原

【Abstract】 The Chinese output of hot metal exceeded 200 million tons in 2003.Domestic and imported iron ores for blast furnace ironmaking are fifty-fifty. The domestic ores are fine magnetite concentrate,and the imported ores mainly are hematite sinter fines. So that, the rational design of blast furnace burden should be a main subject to be studied .Great successes on implementing the principle of refined burden are reviewed in this paper .The current situation and characteristic of domestic and imported iron ores and rational design of blast furnace burden are also discussed .更多还原
