高碱度烧结矿高碱度烧结矿high basicity sinter gaojiandu shaojiekuang高碱度烧结矿(high basieity sinter)碱度(Cao/SiO:)为1.6以上的烧结矿。碱度超过2.5时,则称超高碱度烧结矿。它的含铁矿物为磁铁矿、赤铁矿,私结相矿物主要是铁酸一钙、铁酸二钙,以及少量硅酸二钙和硅酸三钙。高碱度烧结矿机械强度高、粉末少、粒度均匀、还原性好、高温冶金性能好、可落地贮存。 (1)机械强度高、粉末少。高碱度烧结矿主要含有机械强度高、还原性好的私结相矿物铁酸一钙,它在微观上与含铁矿物组成熔蚀或交织结构,勃结牢固。此外,总私结相量也高于自熔性烧结矿和熔剂性烧结矿。但当烧结高硅(5102>8%一10%)含铁原料时,即使烧结矿的碱度已达到1.6,但没有生成足够的铁酸一钙,由于正硅酸钙大量存在,仍有严重的自然粉化。欲获得机械强度好、粉末少的烧结矿,其碱度值应通过具体实验来确定。一般采用低硅(S 1024%~5%)铁料烧结时,碱度达到1.8~2.0即可得到机械强度高、粉末少的高碱度烧结矿。 (2)粒度均匀、还原性好。生产高碱度烧结矿时,烧结料中配入数量较多的熔剂,在烧结过程中可使私结相量增加,加上熔剂的分解,大量气体逸出,使烧结块微观结构上熔融充分、私结较好,而在宏观结构上出现大孔薄壁结构,经过破碎及多次转运,就成为粒度均匀、气孔率高、机械强度好的烧结小块。此外,由于钻结相矿物为易还原的铁酸一钙所组成,且气孔率高,因而还原性良好。 (3)高温冶金性能好。高碱度烧结矿,脉石熔点高、游离FeZO3减少、软熔性和低温还原粉化性都比自熔性烧结矿好。 (4)可落地贮存。高碱度烧结矿由于机械强度高、粉末少,不易自然粉化,因此允许短期落地贮存,以缓冲高炉检修与烧结继续生产的矛盾。 高炉使用高碱度烧结矿,有利于高炉强化生产、增加产量,降低焦比。高碱度烧结矿的缺点是含铁量有所下降(但这可由它的冶金性能的改善和减少直接入炉的熔剂量而得到补偿),烧结脱硫率降低,使其含硫量上升。 生产高碱度烧结矿的工艺要求与普通烧结矿相同,但应尽量选用品位高、含硫低的原料,加强熔剂的破碎,针对原料特点以及高炉合理炉料结构的要求,通过试验研究,选择最佳的烧结矿碱度,以保证获得应有的良好性能。 (蔡汝卓周取定)
