Aiming at the phenomenon of uneven temperature distribution in the curing kiln of three-dimensional PCcomponents, the temperature field distribution model of thecuring kiln was established by using computational fluiddynamics numerical simulation method on the premise of ensuring the curing quality of PC (Precast component) components, and the effects of the location of the spray hole, the presence of fans and the number of fans on the temperature fielddistribution in the curing kiln were studied.The research showsthat when there is no fan, the temperature distribution is very uneven, and the upper and lower temperature difference reaches 26K.By adding the fan simulation experiment, it is found that thetemperature distribution of the curing kiln is more uniform andthe curing time is shortened when there is one fan.Through thesimulation experiment of the position of the spray holes in thecuring kiln, it is found that the temperature distribution is the most uniform when the spray holes are located at the front andback of the curing kiln, the direction is inclined down 45°, andthe temperature distribution is arranged in 1 column and 9 rows, which shortens the time required for uniform temperature distribution inside the curing kiln.
