摘　　要：本文针对钒氮合金生产过程中钒含量波动大、控制难度大的行业共性技术难题,基于原料性质和钒氮合金制备热力学,研究煅烧参数、配料参数对钒氮合金钒含量的影响,构建精准配料模型。结果表明,钒氮合金钒含量受多方面因素共同作用的影响,主要是:煅烧温度、煅烧推速、氮气流量及原辅料中金属杂质含量,最佳的工艺参数为煅烧温度1520℃,煅烧推速为18.5 min/板,氮气流量计值为200 m^(3)/h,催化剂铁粉的加入量y=0.7964x+0.00215,该工艺钒氮合金钒含量可精确稳定控制在77.2%~77.6%。The article focused on the common technical problems which are characterized by large fluctuations in vanadium content and difficult to control in the production process of vanadium-nitrogen alloy.Based on the properties of raw materials and the thermodynamics of vanadium-nitrogen alloy preparation,the influence of calcination parameters and batching parameters on vanadium content of vanadium-nitrogen alloy was studied,and an accurate batching model was constructed.The results showed that the vanadium content of vanadium-nitrogen alloy was affected by multiple factors,mainly including calcination temperature,calcination pushing speed,nitrogen flow rate,and metal impurity content in raw materials.The optimal process parameters were calcination temperature of 1520℃,calcination pushing speed of 18.5 min/plate,nitrogen flow meter value of 200 m^(3)/h,and catalyst iron powder addition amount y=0.7964x+0.00215,so that the vanadium content of vanadium-nitrogen alloy in this process can be precisely and stably controlled between 77.2%and 77.6%.
