Abstract

In view of the heat transfer characteristics of cooling roll and roller, a new type of cooling roll is taken as the research object. On the basis of satisfying the mechanical properties of the cooling roll, a three-dimensional simulation model was established, and the fluid solid coupling conjugate heat transfer of the cooling roll assembly was analyzed by using the CFD method. The results show that the flow at the inlet and outlet reaches equilibrium, the coolant inlet temperature is 80 ℃, and the outlet temperature is 78.7 ℃. Under the condition of ℃, the difference between the maximum temperature and the minimum temperature is less than 5%, which is within a reasonable error range. The surface temperature of the roller is evenly distributed with the temperature of the cooling pipe and arranged in a regular cross shape, which is conducive to sheet forming. The middle temperature of the roller surface is low, and the temperature near the two sides gradually rises. The maximum temperature of the roller is 76.6 ℃, far less than the limit temperature. The heat exchange effect is good, and its structure meets the working performance requirements. In this paper, the conjugate coupled heat transfer analysis provides guidance for the forming design of related cooling roll sheets.
