Abstract：

The amorphous ribbon is prepared by rapid cooling method. The design of runner in cooling copper roller is the key issue in amorphous ribbon forming process. According to ribbon forming requirement, a design criterion was proposed for cooling copper runner design. Based on the criterions, four typical cooling copper roller runners were proposed. Then, their inner-runner flow fields were simulated by fluid-solid coupled method, and the change regulations of the pressure field and the temperature field of different flow channel structure changing with the flow rate were obtained. In order to evaluate the heat transfer ability of different runner structures, a comprehensive heat transfer coefficient was put forward as the index. The simulation results show that the pressure drop of the inlet and outlet of the scattered rib-shaped channel is small, and its heat transfer capacity is better than that of the other three structures. Thus, it is suitable for the cooling copper roller.
