摘　　要：针对影响工业回转窑生产V2O3的工艺及相关参数进行了研究,控制合适的还原温度、出料量的大小、还原煤气流量、筒体转速等可控制产品中杂质含量,使产品质量得到较大提高。试验表明:煤气流量为140～160 m3/h,出料量为320～350 kg/h,还原温度为860～920℃,筒体转速为37.5 s/r时,得到的V2O3产品能够满足钒铁冶炼和氮化钒生产的要求。Major factors influencing V203 production with rotary kiln were examined. It was found that the impurity content of the products could be regulated by controlling reduction temperature, discharge rate, flow rate of reducing gas, and rotating speed of cylinder. Thus, the product quality was greatly im- proved. Experiments show that： the gas flow rate is 140 - 160 m3/h, the discharge capacity of 320 - 350 kg/h, reaction temperature is 860 -920 ℃, the cylinder speed variable is 37.5 s/r, the V203 products can meet the ferrovanadium and vanadium nitride production requirements.
