摘　　要：对国内10家钢铁企业护炉所用的含钛物料进行了调研,研究了不同高炉所用含钛物料的实际情况,分析了不同含钛物料的特性并对其进行评价。调研表明,国内高炉所用含钛物料种类较多,主要为含钛球团矿和块矿,含钛物料的化学成分和采用的运输方式差异较大,主要运输工具为汽车和火车。通过对含钛物料性能和经济指标的分析,得到不同含钛物料的优劣顺序为含钛包芯线、含钛球团矿、含钛块矿、含钛烧结矿和含钛冷固结球团矿。含钛物料的加入方式分为上部加入和下部加入,上部加含钛球团矿、下部使用含钛炮泥的护炉效果较好。The present status of titanium-containing materials from ten steel enterprises in China were investigated.The conditions of the titanium-containing materials from different blast furnaces were introduced,and the properties of the materials were analyzed as well as their comprehensive properties.The results show that the titanium-containing pellet and titanium-containing lump were the main furnace protection materials,and the chemical compositions of titanium-containing materials were quite different.Train and vehicle were the main conveyances.Through the evaluation of the performance and economic indicators of titanium-containing materials,the preferential order of different titanium-containing materials was titanium-containing core wire,titanium-containing pellet,titanium-containing lump,titanium-containing sinter,and titanium-containing unfired pellets.The addition methods of titaniumcontaining materials were divided into upper addition and lower loading.It was concluded that the use of titaniumcontaining pellet with the upper addition and taphole clay containing titanium with the lower addition could achieve a better effect.
