辊身

辊身是轧机支承辊的主要圆柱体部分，设计用于承受金属成形过程中的极端压缩力。它为工作辊提供结构支撑，保持辊缝稳定性，并确保被加工材料上的压力分布均匀。关键尺寸包括辊身长度、直径、凸度轮廓和表面光洁度规格，这些直接影响产品质量和轧机性能。

辊身通过其圆柱表面传递工作辊的轧制力，同时保持精确的几何对中。在操作过程中，液压或机械系统对支承辊组件施加压力，使辊身在受控范围内发生弹性变形。这种变形补偿热膨胀、磨损和载荷变化，确保轧制产品厚度和表面质量的一致性。

The roll barrel operates by transferring rolling forces from work rolls through its cylindrical surface while maintaining precise geometric alignment. During operation, hydraulic or mechanical systems apply pressure to the backup roll assembly, causing the barrel to deform elastically within controlled limits. This deformation compensates for thermal expansion, wear, and load variations, ensuring consistent material thickness and surface quality across the rolled product.
