摘要：

非晶带材成形采用急速冷却方法，其中冷却铜辊内流道设计是非晶带材成形装备研究中的关键问题。根据带材成形的冷却工艺要求，提出了冷却铜辊内流道设计准则。在此基础上，设计出4种典型的冷却铜辊内流道结构。采用流-固耦合传热方法对所设计的4种不同的冷却铜辊内流道流场进行数值模拟分析，得到了不同流道结构所对应的压力场、温度场随进水流量的变化规律。为了评价内流道的换热能力，提出了内流道综合换热系数作为量化换热能力的指标。分析表明：散射肋形流道进出口压降较小，且其换热能力优于其他3种结构，适用于冷却铜辊内流道结构。

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.
