摘　　要：河钢承钢钒钛事业部生产五氧化二钒产品采用"三步法"工艺,煅烧控制为其关键工艺。煅烧温度、反应时间、氧化气氛的控制,大大影响后续铸片熔化生产片状五氧化二钒的工序生产顺行度及生产粉状五氧化二钒的产品质量,造成生产成本浪费。根据煅烧的反应原理,研究低温、快速煅烧工艺,解决煅烧效果不稳定的问题。The production of vanadium pentoxide by Hegang Steel Vanadium and Titanium Division uses the“three-step process”and calcination control is its key process.The control of the calcination temperature,reaction time,and oxidizing atmosphere greatly affects the production process of the subsequent production of flake vanadium pentoxide by melting the vanadium pentoxide and the quality of the powdered vanadium pentoxide product,resulting in a waste of production cost.According to the calcination reaction principle,the low-temperature and rapid calcination process is studied to solve the problem of unstable calcination effect.
