GNK7185-YLR high-frquency pulse fiber laser roller texturning
Product demand of high quality cold-rolled sheet metal and
production technology have increased a lot with the mature metal
market. How to make surface of sheet metal with low roughness, high
peak value and disorder wear-resistant shape has become the most
important technology which highly focus by numerous oversea and
Fiber laser texturing utilize pulse laser beam with high power and
high frequency formed by expander, polanizer and focus lens make
small concave on surface of sheet metal, at that the same time,
flowing gas with specific pressure, direction and rate of flow make
melted material in the melting pool become boss and pit. As a
result of fast heating up of laser, fast cooling down of roller,
crystal grain refined and crystal lattice dislocated while boss and
pin in the stage of solification and phase hardened in 10-5
seconds, finally, the hardness of surface can be up to HV1000.
Steel quantity over can be increased a lot, roller consumption can
be decreased and production can be more stable by fiber laser
textuning. The whole process of surface texturing: performed less
than 20um under surface of roller, no effect on roller figureand
secondary grinding, no medium, and without noise and pollution.
