弧形钢辊是指辊身橡胶层更换为金属层的弯辊，在耐磨性上比橡胶类更耐磨耐压，使用寿命更长，所以应用也比较广泛，使用在收放卷、涂布、贴合、复合等设备上，起到祛皱、扩福作用，同时多种材质可以选择并对金属表面进行加工处理，增加其他其他性能，比如镀硬铬、碳化钨、调质、开槽等工艺，满足不同工作环境要求。

It refers to the bending roll whose rubber layer is replaced by metal layer. In terms of wear resistance, it is more wear-resistant and pressure resistant than rubber, and has a longer service life. Therefore, it is widely used in coiling and unwinding, coating, laminating, laminating and other equipment, which plays a role of wrinkle elimination and expansion. At the same time, a variety of materials can be selected and processed on the metal surface to increase other properties, such as hard chromium plating Tungsten carbide, quenching and tempering, slotting and other processes to meet the requirements of different working environments
