攀钢0.8m_3试验高炉冶炼钒钛烧结矿软熔带的位置、形状和形成过程与冶炼普通矿基木相似,但它的质地疏松,“冰凌”和粘结过渡层没有明显的发展。攀钢烧结矿熔点较低,熔化区间较窄,随着还原的深入,FeO升高,其熔化温度降低不大。攀钢烧结矿的还原性比普通高品位,高碱度烧结矿要差。渣铁熔融物在滴落过程中与焦炭交织发生强烈的过还原作用,使滴落物变稠,成为高炉顺行的障碍。 Panzhihua 0.8m_3 test blast furnace smelting vanadium titanium sinter soft melting zone location, shape and formation process and smelting ordinary ore base wood similar, but its texture is loose, “ice” and bonding transition layer no obvious development. Panzhihua sinter lower melting point melting range is narrow, with the deepening of reduction, FeO increased, the melting temperature decreased little. Pangang sinter reduction than ordinary high grade, high alkalinity sinter worse. Slag iron melt in the process of dripping and coke interweave a strong over-reduction effect, so that dripping thickening, a blast impediment to the line.
