Abstract:

In recent years,application of laser surface treatment technology on the roller surface treatment widely,the main object of this paper is roll,research on laser cladding technology used in bar roll surface,and the laser cladding process parameters are explored.For the laser repair roll processing process,it is difficult to control the cladding quality problem,by changing the laser power,scanning speed,powder feed rate parameters of laser cladding method,through experiments the process parameters in laser power 3.7 kW,scanning speed,powder feed rate of 6 mm·s^-1 19 g·min^-1,the overlapping coefficient in 40%,the best fusion effect of laser cladding,the final tracking operations on roller repairing is well,single groove rolling cladding before the amount is increased nearly 1 times,it creates considerable economic benefits for the enterprise.
