Abstract 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.
