摘　　要：基于物料平衡原理,建立了尾渣全钒含量与焙烧熟料全钒含量、焙烧转化率及浸出率之间的函数方程,并结合某公司实际生产数据对方程的有效性进行了验证.在此基础上,系统研究了方程自变量间相互作用及对尾渣全钒含量的影响,进一步简化了原方程.结果表明:原方程和简化方程能够正确反映尾渣全钒含量和上述因素之间的内在作用规律,可为尾渣全钒含量的实际生产技术控制提供判断依据;而简化方程函数关系简单,更利于实际应用.Based on the material balance principle, a functional relation of the total vanadium content of tailings with the total vanadium content of calcination-clinker, calcination conversion rate and leaching rate was established, and the validity of the equation was proved with industrial production data. The effects of interactions between independent variables in the equation on the total vanadium content of railings were systematically studied ; as a result, the original equation was further simplified. The results show that the internal relation of the total vanadium content of tailings to the above-mentioned factors can be accurately reflected through the original equation and the reduced equation, which can provide a basis of judgment for technical control of the total vanadium content of tailings in actual production. On the other hand, the reduced equation is so simple that it is more favorable to practical applications.
