轧辊具有粘着力，优异的抗压强度、耐磨性和抗腐蚀性等归纳功用，选用高分子复合材料在传动部位磨损规范相对较小的状况下可以现场免拆开修正。

The roller has super strong adhesive force, excellent compressive strength, wear resistance and corrosion resistance, and so on. The polymer material can be free from di***antling in the condition that the wear standard of the tran***ission part is relatively ***all.

冷轧辊在工作过程中要承受很大的轧制应力，加上轧件的焊缝、夹杂、边裂等问题，容易导致瞬间高温，使工作辊受到强烈热冲击，造成裂纹、粘辊、剥落甚至报废。因此，冷轧辊要有抵抗因弯曲应力、扭转应力、剪切应力引起的开裂和剥落的能力，同时也要有高的耐磨性。轧辊的分类方法有多种，主要有：（1）按产品类型分有带钢轧辊、型钢轧辊、线材轧辊等。

Cold roll must bear a lot of rolling stress in the working process, add the weld, inclusion and edge crack of the rolled piece, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, the cold roller must resist the ability of cracking and spalling caused by bending stress, torsional stress and shearing stress, and also has high wear resistance.

整体轧辊是相对于复合轧辊而言的，整体轧辊的辊身外层与心部以及辊颈采用单一材质铸造或锻造而成，辊身外层和辊颈不同的***、性能通过铸造或锻造工艺以及热处理工艺过程来控制和调整。

The whole roll is compared to the roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are and adjusted by the casting or forging process and the heat treatment process.
