摘　　要：辊筒在钢铁加工生产线中发挥着至关重要的作用。低碳钢由于其良好的机械性能和成本效益,通常用作辊筒材料,但其硬度低、耐磨性差、使用寿命短等问题给轧钢生产带来了重大挑战。为解决这些问题,采用电沉积工艺在辊筒表面涂覆Ni-W-SiC复合涂层。该涂层的硬度高达1052 HV,平均摩擦因数为0.3111。工业试验的试验结果表明,未经处理的金属辊筒在出现磨损迹象之前只有15 d的使用寿命,而经过耐磨复合涂层处理的金属辊筒,在使用115 d后磨损明显,从而使辊筒的使用寿命提高了约7.7倍。Rollers play a crucial role in steel processing lines.Low carbon steel is commonly used as the material of rollers due to its good mechanical properties and costeffectiveness,but its low hardness,poor wear resistance and short service life pose significant challenges to steel rolling production.To solve these problems,a Ni-WSiC composite coating is applied on the surface of rollersby using electrodeposition technology.The hardness of the coating is up to 1052 HV,and the average friction factor is 0.3111.The results of industrial tests show that untreated metal rollers have a service life of only 15 d before showing signs of wear,while the wear of metal rollers treated with the wear-resistant composite coating is noticeable after 115 d of use,which improves the service life of rollers by a factor of about 7.7.
