摘　　要：激光熔覆再制造技术能够有效修复水泥生产装备零部件表面磨损,但熔覆层的开裂问题成为制约其广泛应用的关键瓶颈。从热力学和动力学两方面分析了熔覆层开裂的原因,讨论了影响熔覆层开裂的因素和抑制方法,提出了采用基体预热与缓冷方式解决熔覆层开裂的激光熔覆再制造优化技术。实践表明,运用该技术修复轴类、内孔类、衬套类水泥装备,装备使用寿命可提高一倍以上,以辊压机或立磨维修为例,年可节约维修费用10~30万元,经济效益显著。Laser cladding remanufacturing technology can effectively improve the wear resistance of cement production equipment parts,but the cracking of cladding layer has become a key bottleneck restricting its wide application.This paper analyzes the causes of thermodynamic and dynamics,discusses the factors affecting crack formation and suppression methods,and proposes an optimized laser cladding remanufacturing technology using preheating and slow cooling to suppress cracking.The practice has shown that using laser cladding technology to repair shafts,bushings,and internal components of cement equipment can double improve the service life of the equipment.Taking the maintenance of roller presses or vertical mills as an example,annual repair costs can be reduced by 100~300k RMB,demonstrating significant economic benefits.
