An experimental study was conducted on preparation of metallized pellets by agglomeration and pre-reduction of titanium concentrate, for investigating the effects of carbon particle size, carbon dosage, roasting temperature and roasting time on the compressive strength and metallization rate of the pellets. The results show that the raw material is mainly composed of ilmenite with a small amount of magnetite, in which the size fraction of-69 μm accounts for approximately 91.39%, indicating that the material is fine-grained, and has favorable pelletizing performance. It is found that with carbon particle size of-1 mm (unclassified) and addition of carbon at 10%, both the green and fired pellets meet the process requirements in terms of compressive strength. On this basis, after roasting and reduction at 1 200 ℃ in a vacuum furnace for 30 min, qualified pellets with compressive strength of 1 224.60 N/P and a metallization rate of 50.48% can be obtained, which can meet the raw material requirements of electric furnace smelting and separation process. Within the experimental range, appropriately increasing the roasting temperature, prolonging the roasting time, and increasing the carbon addition are all beneficial to improving the metallization rate of pellets.

开展钛精矿造块及预还原制备金属化球团试验研究，考察配碳粒度、配碳量、焙烧温度及焙烧时间对球团抗压强度和金属化率的影响。结果表明，钛精矿主要由钛铁矿和少量磁铁矿组成，且-69 μm粒级约占91.39%，属细粒物料，具备良好成球条件。在配碳粒度-1 mm（未分级）、配碳量10%条件下，生球和熟球抗压强度均符合工艺要求。生球在1 200 ℃真空还原焙烧30 min，可获得抗压强度1 224.60 N/P、金属化率50.48%的球团，满足电炉熔分工艺的原料要求。在试验范围内，适当提高焙烧温度、延长焙烧时间及增加配碳量均有利于提升球团金属化率。
