摘　　要：首钢京唐公司通过往自产球团中小比例配加含钛矿粉,进行了含钛球团生产试验。结果表明:在京唐带式焙烧机焙烧工艺制度下,配加5%含钛球团粉生产的含钛球(TiO2含量0.8%左右)具有品位高、SiO2含量低、抗压强度好、成本低等特点,且其还原膨胀率为19.35%,比常规球团低;用其替代京唐高炉炉料中的常规球团后,炉料熔滴性能合适,能起到高炉护炉和降低成本的双重作用。The production experiment of titanium-containing pellets was conducted by adding titanium-containing fines with a small proportion in self-producing pellets in Shougang Jingtang company. The results shows that,under Jingtang straight grate roasting process system,the titanium-containing pellets produced by adding 5% titanium-containing fines（ the TiO2 content is about 0. 8%）,have such characteristics as high grade,low SiO2 content,good compressive strength and low cost. In addition,the titanium-containing pellets produced with addition of 5% titanium-containing pellet fines have a reduction swelling ratio of19. 35% which is lower than that of conventional pellets. After using the titanium-containing pellets to replace the conventional pellets of Jiangtang BF burden,the BF burden droplet performance is suitable,playing dual function in protecting BF and decreasing cost.
