Dab tsi yog qhov txawv ntawm Laser txiav tshuab txiav cov khoom siv hlau sib txawv?
General carbon hlau
Tsawg-carbon steels nrog cov ntsiab lus hlau ntau dua 99 feem pua yog tsim rau oxygen-melting laser txiav. Cov tshuaj tiv thaiv oxidation ntawm hlau yuav ua kom muaj cua sov ntau, uas tuaj yeem txo cov kev xav tau ntawm lub zog ntawm laser. Tsis tas li ntawd, cov pa oxygen tuaj yeem nkag mus rau hauv cov khoom siv melting los ntawm cov hlau oxidation cov tshuaj tiv thaiv. Vim yog qhov tsawg viscosity ntawm oxidation, nws yog ib qho yooj yim kom raug cua tshuab. Yog li ntawd, laser txiav qis-carbon steel yog siab thiab qhov kev txiav yog du.
Stainless hlau
High-pressure nitrogen feem ntau yog siv los txiav stainless hlau, siab laser zog, dawb ci thiab tsis oxidized thiab tsis hloov, thiab cov plaub hau tsawg dua. Yog tias nws raug txiav nrog oxygen, qhov nrawm tuaj yeem nrawm dua ntawm tib lub zog, tab sis qhov kev txiav yuav oxidized thiab dub. Xav tias stainless hlau muaj chromium los yog npib tsib xee ntawm cov khoom xyaw sib txawv, ntau hom stainless hlau yuav xav tau cov kev txiav txawv txawv, thiab cov teebmeem kuj txawv.
Khoom siv tooj liab
Tooj thiab txhuas zoo sib xws. Lub reflectivity ntawm lub laser yog siab heev, tab sis liab (liab doog) tooj liab yuav tsum tau tshuab oxygen kom zoo dua txiav. Yuav muaj cov plaub hau nyob rau tom qab, uas yooj yim rau khawb tawm.
Aluminium
Vim tias txhuas thiab nws cov alloys muaj kev cuam tshuam ntau dua ntawm laser, lub zog siab dua yuav tsum tau txiav kom zoo dua. Txiav tuaj yeem siv nrog cua lossis nitrogen. Qhov kev txiav yog dawb, tab sis txawm hais tias nws yog huab cua lossis nitrogen txiav, muaj me me ntawm cov plaub hau ua npuas ncauj rau sab nraub qaum, tab sis nws yooj yim tshem tawm.
Nickel alloy
Lub laser txiav ntawm nickel alloys zoo ib yam li stainless hlau txiav. Txawm li cas los xij, vim yog lub siab viscosity ntawm melting npib tsib xee, lub slag feem ntau yuav lo rau sab nraum qab ntawm qhov txiav latch, uas yog ib qho yooj yim los tsim burrs, thiab nws feem ntau zoo dua txiav nrog oxygen.
Titanium thiab nws cov alloy
Oxygen txiav yuav ua rau muaj kev cuam tshuam loj heev vim tias cov tshuaj tiv thaiv oxidation ntawm titanium tso tawm ntau lub zog thermal. Txawm hais tias qhov nrawm nrawm, nws tuaj yeem yooj yim ua rau qhov incision hlawv ntau dhau. Feem ntau hais lus, siv cua txiav. Muaj me me ntawm cov plaub hau residue nyob rau tom qab, tab sis nws yog ib qho yooj yim rau tshem tawm, yog li nws yooj yim dua los tswj cov nyhuv txiav. Nitrogen txiav tuaj yeem txo qhov teeb meem ntawm oxidative pollution, tab sis cov nyhuv thermal ntawm qhov kev txiav tuaj yeem hloov pauv cov khoom siv ntawm cov khoom siv.
