本实验以球团热态性能检测为主,对攀枝花铁精矿氧化球团还原过程的膨胀性、粉化性等进行探讨,以寻求其高炉冶炼的可能性。选用CaO/SiO_2=0.29～1.5的碱度,以链篦机-回转窑试验装置焙烧的球团。T_(Fe)=51～46％。以差动式膨胀仪测定球团线膨胀率P(％);以 In this experiment, the thermal performance of pellets was mainly measured, and the swelling and pulverizability of the oxidized pellets of Panzhihua Iron Concentrate were discussed in order to seek the possibility of smelting blast furnace. Selection of CaO / SiO_2 = 0.29 ~ 1.5 alkalinity, grate - rotary kiln test device firing pellets. T_ (Fe) = 51 ~ 46%. The differential dilatometer was measured pellet linear expansion rate P (%);
