Abstract:
      The extrusion uniformity of the compound flow field in the non-isothermal cladding head was studied. The results showed that the simulated variation trends of the pressure,temperature and flow velocity of the compound flow field in the non-isothermal cladding head were similar to those of the actual situation, and the simulation test was an effective method to analyze the compound flow field of the cladding head. The effects of the flow channel parameters in the cladding head(feed inlet position,feed inlet diameter and core wire traction speed) which affected the cladding uniformity were determined,which provided a theoretical basis for the optimization of the cladding process and the flow channel parameters of the cladding head. Moreover,the evaluation method of the matching between the core wire traction speed and the compound flow at the feed inlet during the cladding process was established. This study provided theoretical guidance for the determination of the cladding process and the flow channel parameters of the cladding head.
