摘　　要： 介绍了金属带材表面的正犁削翅成形原理及翅化共轭环塔填料的加工过程 ,分析了在铝带材表面上形成规则翅片的犁削条件 ,测试比较了翅化共轭环与光滑共轭环的压降损失和传质单元高度。结果表明 ,成翅形状和高度主要取决于刀具几何参数及犁切深度。共轭环填料翅化后 ,在喷淋密度为 4 0～ 10 0m3/(m2 ·h)时 ,单位填料层压降损失平均增加 16 .3% ,而传质单元高度则平均降低 18.3%。共轭环填料翅化后较适合于在中等喷淋密度下操作。 The mechanism of normal plough for fin formation on metal surface and the manufacturing process of aluminum conjugate ring with fins on surface for packing towers were introduced. Special attention was given to the analysis of the plough condition for forming regular fin. In addition, the loss of pressure drop and the height of mass transfer unit of this fin packing were measured and compared with that of smooth surface packing in the same size. The result showed that the shape and height of the fin structure were depended on the tool geometric parameters and the plough depth. And the experimental data of the packing performance determination demonstrated that the pressure drop of the fin conjugate ring was increased 16.3%, but the height of mass transfer unit was decreased by a factor of 18.3% on an average at the liquid load range of 40 to 100m^3/(m^2·h) compared with that of smooth surface packing. The fin packing was suitable for operation at a moderate liquid load.
