Abstract：

According　to　the　cleaning　demand　of　cold　rolled　oil　on　DC04　cold　rolled　strip　surface,　we　use　COMSOL　Multiphysics　software　to　establish　the　temperature　field　distribution　and　oil　stain　removal　process　model　of　nanosecond　pulse　laser　cleaning　oil　stain　on　DC04　cold　rolled　strip　surface.　The　results　show　that　when　the　spot　radius　is　80　μm　and　the　laser　energy　density　reaches　3.　48　J/cm2,　the　oil　can　be　basically　removed.　Then,　a　nanosecond　pulsed　laser　is　used　to　clean　cold　rolled　oil　on　the　surface　of　cold　rolled　strip　steel.　The　results　show　that　when　the　laser　energy　density　exceeds　3.　48　J/cm2　and　the　laser　spot　overlap　rate　is　50%,　the　oil　pollution　can　be　removed,　which　is　consistent　with　the　simulation　results.　In　addition,　the　influence　of　laser　spot　overlap　rate　on　laser　cleaning　effect　is　also　studied.　The　results　show　that　the　laser　energy　density　should　be　increased　to　4.　47　J/cm2　when　the　spot　overlap　rate　is　reduced　to　37.　5%.　Therefore,　nanosecond　pulsed　laser　can　effectively　clean　the　cold　rolled　oil　on　the　surface　of　DC04　cold　rolled　strip　without　causing　obvious　damage　to　the　surface　of　the　strip,　which　provides　a　reference　for　determining　the　process　parameters　of　nanosecond　pulsed　laser　to　clean　other　kinds　of　materials.　©　2024　Universitat　zu　Koln.　All　rights　reserved.
