【摘要】 为研究菲律宾红土镍铁矿的烧结特性,对烧结原料进行化学成分测定、热重(TG)、差热(DTA)实验以及 X 射线衍射(XRD) 分析。针对其原料特点设计了正交实验方案,进行了烧结杯实验。研究了配碳量和石灰石添加量对红土矿烧结速度、成块率、脱硫率以及利用系数的影响。实验结果得到,当混合料配碳量为200 kg/t 矿、石灰石含量为162.5 kg/t 矿时,烧结效果较好。分析发现,石灰石配加量对菲律宾红土矿烧结过程的影响比配碳量的影响大。更多还原

【Abstract】 The chemical composition measurement of raw materials,the Thermogravimetric(TG), differential thermal analysis (DTA) and X-ray diffraction(XRD) experiments were carried out to study the sintering characteristics of Philippines nickeliferous laterite.According to its raw materials, orthogonal test scheme is designed and experimental sintering is carried out.The effects of carbon mixture ratio and addition of limestone on sintering velocity, agglomeration ratio,desulphurizing ratio and utilizing coefficients were researched.The experimental results show that sintering process is more effective when the carbon composition is 200 kg/t and limestone composition is 162.5 kg/t in ore. Analysis shows that the influence of the amount of limestone is more significant than that of the carbon mixture ratio on the sintering process.更多还原
