In order to solve the problems of imprecise feed mixing system,low yield,high energy consumption,high unit consumption of vanadic oxide,unstable vanadium content in the product,high carbon blending ratio,and reducing carbon emissions in the production of vanadium-nitrogen alloy;it analyzes the equipment operation in the material mixing system,studies the masonry technology and production mechanism of vanadium-nitrogen alloy in pusher kiln,and the reduction nitriding process curve of pusher kiln equipment.By combining material characteristics and energy consumption of the push plate kiln,optimizing the original system and controlling the production process,combined with the construction of the MES system,horizontal and vertical information integration between various production processes is achieved;establish the optimal operating range for the parameters of the push plate kiln through practical verification.The best operating parameter interval is determined through the practical verification of the temperature value and reaction rate in the working area of the pusher kiln.Precise control of the production process achieves with the stable carbon ratio at the lower limit,the vanadium content maintains at 77.5%±0.1%,the reasonable reduction of carbon dioxide emission,the energy consumption of the pusher kiln can reduce by 53%,and the increasing efficiency,energy saving and carbon reduction have been achieved.
