Abstract: The preparation process of vanadium nitrogen was a one-step nitriding reduction and heat transfer process in double pusher kiln, which was a long production cycle and high energy consumption process. In order to reduce energy consumption effectively, the temperature field simulation of vanadium-nitride production in push plate kiln was made for the first time, which has a certain guiding effect on the optimization equipment. A three-dimensional heat transfer model of double pusher kiln's chamber was established, and take the ANSYS Workbench as a platform to si-mulate the typical heating section of vanadium nitrogen, then the temperature field distribution of vanadium nitrogen in different heating sections was obtained. By validating the simulation results, some measures were taken to increase the heating rate and optimization the pusher kiln speed, further shorter production cycle. The optimization results show that, the speed of the material ball through the main kiln decreased 108 min, production at the original condition of foundation can be increased by 6.45%, the amount of power consumption for tons reduced to 93.95% than before.
