辊压机是上世纪80年代中期发展起来的新型水泥节能粉磨设备，对其辊面的及时堆焊维护是保证辊压机使用寿命的关键。辊面堆焊维护得好可大大减少停机堆焊次数，为正常生产提供了保证，充分发挥辊压机高效率、低能耗的优越性。 squeeze rollers is developed in 80s. It is the new type cement milling equipment. Hard-facing is the key for prolonging the service-life and reducing repair times. 磨损严重的挤压辊 The seriously worn squeeze rollers 嘉克采用专用辊压机辊面堆焊再制造而研发的适应辊压机磨损特点的焊材，并配合科学的堆焊工艺，能达到比较满意的堆焊效果，大大延长辊压机耐磨层的使用寿命，降低堆焊再制造的次数。 The developed squeeze rollers remanufacture by ARC is selecting suitable welding material to prolong service life and reduce the times for remanufacture. 辊压机堆焊材料的选择 The demand for material 1）打底层焊丝要求韧性好，作为止裂层焊在最底层 The backing welding wire must have good tenacity and be placed at the bottom as crack-preventing layer 2）良好的过渡层材料选择及焊接 The selection and welding of the fine material at the transition layer are the first premise of an effective and safe operation of the hard layer 3）辊面焊材要求耐磨性能优越 The welding material on the surface of the press roll must have a good wear-resisting property. 4）花纹层材料要求抗剧烈磨粒磨损及中等冲击磨损 The material on the patterns layer must have high abrasive wear resistance and medium impact abrasion resistance 辊体预处理 Squeeze rollers after surface pretreatment 辊体探伤 Squeeze rollers penetration inspection before overlaying welding 堆焊好的挤压辊 Squeeze rollers after overlaying welding 挤压辊表面花纹 Pattern on the surface of the squeeze rollers
