唐钢石人沟铁矿石具有良好的可选性,结晶粒度粗,有害杂质含量极低,是生产海绵铁的优质原料。COF-C直接还原法工业试验证实,可生产出金属化率大于92%的金属化球团;将磁铁矿铁精粉ω(TFe)提高到69%以上,用石油焦还原,可以获得ω(TFe)高于90%的海绵铁产品
Tangguanshigou iron ore has good selectivity, coarse grain size, low content of harmful impurities, is the production of sponge iron high quality raw materials. COF-C direct reduction method industrial test confirmed that the metallization can produce more than 92% metallized pellets; the magnetite iron powder ω (TFe) increased to 69% or more, with petroleum coke reduction can be obtained ω (TFe) is higher than 90% of sponge iron products
