Chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha 316L zonse ndi austenitic, zokhala ndi chromium yofanana (16–18%), nickel (10–14%), ndi molybdenum yochuluka (2–3%). Kusiyana kwakukulu ndi kuchuluka kwa kaboni wa 316L pansi pa 0.03%, poyerekeza ndi 0.08% pa 316. Kutsika kwa kaboni kumachepetsa kwambiri chromium carbide panthawi yogwiritsira ntchito zowotcherera.
316 poyerekeza ndi 316L
*
Chromium carbide imagwera pamalire a tirigu pamene kutentha kwakukulu kumachitika, makamaka pakati pa 450°C ndi 850°C, monga m'madera omwe kutentha kumakhudzidwa ndi weld. "Sensitization" iyi imawononga chromium m'deralo ndipo imayambitsa dzimbiri pakati pa granular, makamaka m'malo ovuta a chloride.
Magwiridwe antchito, Kukana dzimbiri, ndi Kutha kusunthika
Zinthu Zotsutsana ndi Kudzimbiri
Chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha 316L zimalimbana kwambiri ndi dzimbiri la mpweya ndi mankhwala chifukwa cha kuchuluka kwa molybdenum pakati pa 2–3%. Kusiyana pakati pa chitsulo chosapanga dzimbiri cha 316 ndi 316L kuli mu momwe zimagwirira ntchito pambuyo popangidwa: kuchuluka kwa kaboni wa 316L ndi ≤0.03%, poyerekeza ndi ≤0.08% ya 316, zomwe zimachepetsa kwambiri kuchuluka kwa carbide m'malire a tirigu pambuyo powotcherera. Kapangidwe kameneka kamapangitsa chitsulo chosapanga dzimbiri cha 316L kukhala chabwino kwambiri m'malo omwe ali ndi ma chloride ndi ma acid nthawi zonse, monga zida zam'madzi, mapaipi opangira, ndi matanki a mankhwala, kusunga kukana dzimbiri m'malo obisika, ngakhale m'malo obisika.
Zoganizira Zokhudzana ndi Kutha Kuthira
Chitsulo chosapanga dzimbiri cha 316L chimapereka kuthekera kolumikizana bwino kwambiri kwa nyumba zolumikizidwa m'mafakitale omanga, azachipatala, ndi mankhwala. Kuchuluka kwake kochepa kwa kaboni (u003c0.03%) kumaletsa kupangika kwa chromium carbide panthawi ya kutentha, kuteteza dzimbiri pakati pa granular ndi kutayika kwa dzimbiri pa malo olumikizirana. Khalidweli limapewa ma weld ofooka, kupanga dzimbiri, komanso kukonza kokwera mtengo, zomwe zimakhala zoopsa pamene 316 stainless steel imagwiritsidwa ntchito molakwika pakugwiritsa ntchito ma weld ambiri kapena kutentha kobwerezabwereza. Mwachitsanzo, zida zoyikiramo mankhwala, zotengera zopanikizika, ndi zida zopangira chakudya zimagwiritsa ntchito 316L yokha kuti zipewe kulephera kwa weld zone.
Mavuto Osiyanitsa 316 ndi 316L
Malire a Kuyang'ana kwa Maso
Chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha 316L sizingasiyanitsidwe ndi maso. Mtundu wofanana, kunyezimira, ndi kutha kwa pamwamba kumapangitsa kuti macheke a kuwala asagwire ntchito potsimikizira mtundu wake. Opanga, opanga zinthu, ndi ogulitsa ali pachiwopsezo cholembedwa molakwika panthawi yogula, kusungira, ndi kupanga. Kusankha kolakwika kumawononga ubwino wa weld, zomwe zimachepetsa ubwino wa 316L kuposa chitsulo chosapanga dzimbiri cha 316. Kugwirizana kolakwika kumawonjezera ntchito zokonza ndipo kungaphwanye kutsatira miyezo m'magawo azamankhwala, chakudya, ndi zida zamankhwala, komwe mpweya wochepa umafunika.
Zoopsa za Kusadziwika Molakwika
Nyumba zolumikizidwa pogwiritsa ntchito 316 m'malo mwa 316L zimachititsa kuti dzimbiri liziyenda bwino pamalo omwe kutentha kumakhudza, zomwe zimachepetsa nthawi yogwirira ntchito. Malo okhala ndi chloride yambiri amafulumizitsa kuwonongeka kumeneku—zitsanzo zikuphatikizapo mapaipi am'madzi, matanki a mankhwala, ndi zida zogwirira ntchito zomwe zimagwira ntchito pamwamba pa 450°C. Kusakaniza kamodzi kokha kungayambitse nthawi yotsika mtengo yosakonzedweratu. Zolakwitsa zobwerezabwereza zimayambitsa zilango zachuma, kudandaula za chitsimikizo, komanso kutayika kwa kutsata. Kuwunika kwa malamulo nthawi zambiri kumafuna umboni wa giredi, zomwe zikuwonetsa kufunika kotsimikizira zinthu molondola. Kusanthula kwa ED XRF ndi XRF spectrometer yogawa mphamvu, makamaka zida zonyamulika za ED XRF monga Lonnmeter, kumapereka kusiyana kwa zinthu zofunika kwambiri pakuwongolera bwino zinthu komanso chitsulo chosapanga dzimbiri cha 316 vs 316L chogwiritsira ntchito zolumikizira.
ED-XRF --Chida Chodalirika Chodziwitsira Zitsulo Zosapanga Dzimbiri
Mfundo za ED-XRF Spectrometry
Mphamvu Yogawa Mphamvu ya X-Ray Fluorescence (ED-XRF) imayesa kapangidwe ka zinthu mwa kuyeza mpweya wa X-ray wochokera ku zitsanzo za chitsulo chosapanga dzimbiri. Spektrometer imapambana posiyanitsa chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha 316L poyesa molondola kuchuluka kwa zinthu zosakaniza, kuphatikizapo chigawo chachikulu cha kaboni chomwe chimafotokoza kusiyana pakati pa 316 ndi 316L chitsulo chosapanga dzimbiri. ED-XRF siifuna miyezo yowunikira, kuwerengera mwachindunji kuchuluka kwa zinthu kudzera mu njira ya Fundamental Parameter (FP) ya zinthu zonse zazikulu monga Cr, Ni, Mo, ndi Fe. Ndi chida chowunikira cha silicon drift, ED-XRF imapereka kusanthula kosawononga, nthawi yeniyeni koyenera malo opangira zinthu ndi ma lab owongolera khalidwe. Kukonza matrix ndi ma algorithms a mapulogalamu kumatsimikizira kuti zotsatira zake zimakhala zolondola kwambiri popanda kufunikira kusungunuka kwa zitsanzo kapena kukonza pamwamba.
Ubwino Woposa Mayeso Achizolowezi
ED-XRF imathandiza kutsimikizira bwino magiredi poyerekeza ndi kusanthula kwa mankhwala kapena kusanthula kowononga. Ogwira ntchito nthawi yomweyo amasiyanitsa pakati pa chitsulo chosapanga dzimbiri cha 316 ndi 316L chowotcherera, zinthu zomwe zili m'sitolo, ndi kugwiritsa ntchito motsatira malamulo. Kujambula kamodzi kokha kumapereka ma profiles a alloy onse, kuthandizira kutsimikizira khalidwe mwachangu ndikuchepetsa chiopsezo cha kusakanikirana kwa magiredi. Njirayi imawonjezera kuchuluka kwa ntchito, imachepetsa ndalama zonse zoyesera, ndikuchotsa kuchedwa komwe kumachitika mu ntchito za laboratori kunja kwa malo.
Kugwiritsa Ntchito Lonnmeter XRF Alloy Analyzer Kuti Mutsimikizire 316/316L
Zinthu Zofunika Kwambiri ndi Ma Parameters Ogwira Ntchito
Lonnmeter XRF Alloy Analyzer imachita ma scan apamwamba kwambiri okhudzana ndi zinthu zosakaniza mu chitsulo chosapanga dzimbiri cholimba. Ma spectrometry ake amayesa bwino kuchuluka kwa kaboni kotsika kofunikira kwambiri posiyanitsa chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha 316L, chomwe chimasiyana makamaka ndi gawo la kaboni pansi pa 0.03% mu 316L. Kukana chinyezi ndi fumbi mwamphamvu, nyumba yolimba, ndi chitetezo cha kugwedezeka kumalola kugwiritsidwa ntchito modalirika m'mafakitale achitsulo, m'masitolo opanga zinthu, ndi m'malo omanga. Kugwira ntchito ndikosavuta, kumafuna maphunziro ochepa. Ma interface amathandizira malipoti a digito ndi CSV ndi PDF export kuti akwaniritse zolembedwa zotsatizana. Lonnmeter imagwira ntchito m'manja, yoyendetsedwa ndi batri, komanso yosakwana makilogalamu awiri, imalola kusanthula kwa ED XRF pamalopo komanso kutsata bwino zinthu zomwe zili m'sitolo.
Chifukwa Chiyani Muyenera Kupempha Mtengo?
Lonnmeter XRF Analyzer imachepetsa zolakwika za wogwiritsa ntchito komanso kukonzanso kokwera mtengo mwa kutsimikizira giredi yokha. Magulu opereka chithandizo amakonza bwino momwe ntchito ikuyendera komanso kutsimikizira khalidwe lake pogwiritsa ntchito zotsatira za digito, kuchepetsa nthawi yogwira ntchito. Kupempha mtengo kumalumikiza maguluwo ku zida zomwe zakonzedwa, chithandizo chaukadaulo, ndi maphunziro ogwiritsira ntchito mosavuta muzofunikira zonse zofunika kuzindikirika kwa alloy.
Mafunso Ofunsidwa Kawirikawiri
Kodi kusiyana kwakukulu pakati pa chitsulo chosapanga dzimbiri cha 316 ndi 316L ndi kotani?
Chitsulo chosapanga dzimbiri cha 316L chimachepetsa kuchuluka kwa kaboni pansi pa 0.03%, poyerekeza ndi 0.08% mu chitsulo chosapanga dzimbiri cha 316.
Nchifukwa chiyani 316L ndi yoyenera kwambiri pa zomangamanga zolumikizidwa?
Mpweya wotsika wa 316L umaletsa kupangika kwa chromium carbide m'malo olumikizirana ndi kutentha. Izi zimaletsa kukhudzidwa ndi kutentha, zomwe zimapangitsa kuti dzimbiri lisawonongeke mukamaliza kulumikiza kapena kugwiritsa ntchito kutentha kwambiri.
