In order to address distortion caused by cooling speed for aluminum profile in water spray quenching processing, a finite element model for cooling process in water spray of the extruded aluminum profile was developed on the basis of the FLUENT and ANSYSWORKBENCH software platform. The temperature field, the residual stress and the strain of cross section in quenching processing were analyzed under three runs with different water spray speeds. After process parameters were optimizated, the results showed that the nozzle size speed of the section profiles in different parts was more reasonable, and the distribution of temperature and equivalent stress was more uniform. It presented the smallest equivalent stress and strain of cross section. Finite element analysis can help improve nozzle distribution and spray velocity in the quenching process of the aluminum profile, which can provide guidance for practical production in industry.
