轧辊是轧钢厂的主要生产工具之一,直接影响着轧钢机工作的技术经济指标。在板钢厂,轧机的定期与非定期换辊(如辊身压痕、掉肉、龟裂、网纹等),轧辊使用寿命以及轧件的表面光洁程度等,都取决于所使用的轧辊性能。过去,鞍钢各板钢厂使用的球墨铸铁轧辊直径大都是比较小的。轧板厂投产后使用的轧辊全部是进口(尺寸、材质见表1),万能轧机与连轧机支持辊直径较大,均为锻钢轧辊,
Rolling mill is one of the main production tools, a direct impact on the technical and economic indicators rolling mill work. In sheet mills, periodic and unscheduled roll changes of the mill (such as roll indentations, dropped meat, cracks, textures, etc.), the service life of the rolls, and the smoothness of the surface of the rolled stock depend on the roll used performance. In the past, the ductile iron rolls used by Ansteel’s steel mills were mostly smaller in diameter. After rolling mill put into operation all the rolls are imported (size, material see Table 1), universal mill and rolling mill support roller larger diameter, are forged steel roll,
