摘要: 实验室条件下,研究了硼铁矿对高铬型钒钛矿烧结工艺及冶金性能的影响.研究表明:随着硼铁矿质量配比的升高,垂直烧结速度、成品率、转鼓指数、烧结杯利用系数、综合指标及低温还原粉化性能均呈先升高后降低的趋势,在硼铁矿质量配比为5.0%时,以上各指数均达到最高值,分别为28.84mm·min-1,86.02%,61.2%,1.919t·(m2·h)-1,363及90.76%,均优于未配加硼铁矿时的烧结矿性能.因此,烧结矿性能得以优化,可以为高炉冶炼提供更为优质的高铬型钒钛烧结矿.

Abstract: Experiment on the effects of boron-bearing iron concentrate applied to sintering of high chromium vanadium-titanium magnetic ore was carried out under laboratory conditions. The results show that, with the increase of boron-bearing iron concentrate addition, vertical sintering speed, sinter yield, tumbler strength, utilization coefficient raise at first then decrease, as well as composite indicator and RDI+3.15. When boron-bearing iron concentrate addition is 5.0%, the maximum values of the above indexes are 28.84mm·min-1, 86.02%, 61.2%, 1.919t·(m2·h)-1, 363 and 90.76%, respectively. The properties of sinter ore with adding 5.0% boron-bearing iron concentrate ore are superior to the properties of sinter ore without boron-bearing concentrate. As a result, properties of high chromium vanadium-titanium magnetite sinter ore are optimized with adding balanced amount of boron-bearing iron concentrate, and can meet the higher requirements of blast furnace process.

Key words: high chromium vanadium-titanium magnetite ore, sinter ore, boron-bearing iron concentrate, metallurgical performance, composite indicator
