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28.84 mm.min-1,86.02%,61.2%,1.919 t.(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.

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. 84 mm.min-1 ,86. 02%,61. 2%,1. 919 t.(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.
