Laser txiav siv lub tsom iav tsom iav kom pom lub teeb pom kev ntawm cov khoom siv los yaj cov khoom. Nyob rau tib lub sijhawm, cov roj compressed coaxial nrog lub laser beam yog siv los tshuab cov khoom yaj thiab ua rau lub laser beam thiab cov khoom txav mus rau ib leeg raws li ib qho kev sib tw, yog li tsim tau ib qho zoo. Zoo li slits.
Ua rau overheating
1 khoom nto
Cov pa roj carbon steel yuav oxidize thaum raug huab cua thiab tsim cov oxide nplai lossis oxide zaj duab xis rau saum npoo. Yog hais tias lub thickness ntawm cov zaj duab xis / daim tawv nqaij tsis sib npaug los yog nws tau tsa thiab tsis nyob ze ntawm lub rooj tsavxwm, nws yuav ua rau lub rooj tsavxwm nqus cov laser unevenly thiab lub tshav kub generated yuav tsis ruaj khov. Qhov no cuam tshuam rau ② kauj ruam ntawm kev txiav saum toj no. Ua ntej txiav, sim muab nws nrog rau sab nrog qhov zoo tshaj plaws saum npoo ntsej muag.
2 Thaum tshav kub kub
Lub xeev txiav zoo yuav tsum yog tias cov cua sov tsim los ntawm laser irradiation ntawm cov khoom thiab cov cua sov uas tsim los ntawm oxidative combustion tuaj yeem ua tau zoo diffused rau ib puag ncig thiab ua kom txias zoo. Yog tias qhov txias tsis txaus, overheating yuav tshwm sim.
Thaum cov txheej txheem kev ua haujlwm muaj ntau qhov me me, cov cua sov yuav txuas ntxiv mus ntxiv raws li kev txiav ua tiav, thiab kev kub nyhiab tuaj yeem yooj yim tshwm sim thaum qhov thib ob ib nrab raug txiav.
Txoj kev daws teeb meem yog kom nthuav tawm cov duab ua tiav kom ntau li ntau tau kom cov cua sov tuaj yeem tawg tau zoo.
3 Overheating ntawm cov ces kaum ntse
Cov pa roj carbon steel yuav oxidize thaum raug huab cua thiab tsim cov oxide nplai lossis oxide zaj duab xis rau saum npoo. Yog hais tias lub thickness ntawm cov zaj duab xis / daim tawv nqaij tsis sib npaug los yog nws tau tsa thiab tsis nyob ze ntawm lub rooj tsavxwm, nws yuav ua rau lub rooj tsavxwm nqus cov laser unevenly thiab lub tshav kub generated yuav tsis ruaj khov. Qhov no cuam tshuam rau ② kauj ruam ntawm kev txiav saum toj no. Ua ntej txiav, sim muab nws nrog rau sab nrog qhov zoo tshaj plaws saum npoo ntsej muag.
Kev kub nyhiab ntawm cov kaum ntse ntse feem ntau yog tshwm sim los ntawm kev tsim hluav taws xob vim tias qhov kub ntawm cov kaum ntse ntse tau nce mus rau qib siab heev thaum lub laser hla nws. Yog tias qhov nrawm nrawm ntawm lub laser beam ntau dua qhov kub hloov ceev, overburning tuaj yeem zam tau zoo.
Yuav ua li cas daws overheating?
Nyob rau hauv ib txwm muaj xwm txheej, lub tshav kub conduction ceev thaum kub kub yog 2m / min. Thaum txiav ceev ntau dua 2m / min, melting poob yuav tsis tshwm sim. Yog li ntawd, siv high-power laser txiav yuav zoo tiv thaiv overburning.
