2 四川德胜 260m 烧结工程设计及提高强度生产实践 王代军 贺万才 李长兴 张全申 (北京首钢国际工程技术有限公司，北京 100043) 1 摘 要 钒钛磁铁精矿具有低铁、低硅、高钛、高亚铁等特点，以此为主要烧结铁矿原料的烧结矿，容易生成高熔 点的矿物结构，使得烧结矿的强度低。德胜烧结工程采取单设燃料破碎、集中配料、强化制粒、新型宽皮带加九辊 布料、实施低硅高碱度和厚料层烧结；烧结机采用集中智能润滑系统和板簧密封滑道、在烧结机头尾设计柔磁性密 封装置来降低漏风率；工程投产后，以钒钛磁铁精矿为主烧结的烧结矿强度达到 72% 以上。 关键词 钒钛磁铁精矿 难点 措施 转鼓指数 2 The Practice of Designing Sichuan Desheng 260m Sinter Engineering and Increasing Strength Wang Daijun He Wancai Li Changxing Zhang Quanshen (Beijing Shougang International Engineering Technology Co., Ltd., Beijing, 100043) Abstract The vanadium titanium magnetite concentrate has such characteristics as low iron, low silica, high tatanium, high ferrous iron etc., the magenetite concentrate is used as sintering main raw material, it is easy to produce sinter with mineral structure of high melting point, make the sinter strength lowing. DeSheng sinter engineering, through adopting single fuel breaking 、proportioning focusly 、intensifying granulation 、newly-wide belt and nine rolls distributor 、 implementation of low silica high basicity and deep bed sintering；The sinter machine applies focus intelligent lubrication system and sealed slide spring、installing soft magnetic seal to low leakage ；Put into operation, thesinter strength is increased to more than 72%.
