Mukuwona chitsulo chosapanga dzimbiri cha 304L pamapepala ambiri, ndi phokoso lakumbuyo. Mtundu wocheperako wa 304, wabwino kuwotcherera, umalimbana ndi dzimbiri-aliyense amadziwa zimenezo, sichoncho? Ndiwo msampha woyamba. M'zochita, kusiyana pakati pa ASTM spec ndi momwe zimakhalira m'malo opangira makina kapena pamalo ogulitsira makina ndipamene ntchito yeniyeni imachitika. Ndawona ma projekiti ambiri akupunthwa chifukwa wina adangoyika bokosi la 304L osaganizira za mapangidwe enieni, kutentha, kapena zomwe zidzawululidwe. Sichipolopolo chamatsenga; ndi zinthu ndi quirks mumaphunzira podetsa manja anu.
L Si Kalata Yakha
Aliyense amayang'ana kwambiri za carbon, max 0.03%, kuteteza carbide mvula panthawi yowotcherera. Ndilo buku lophunzirira. Koma pakuponya ndalama, womwe ndi mkate wathu ndi batala Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., L amatanthauza chinthu china panthawi yothira. Melt amachita mosiyana. Ndizochita zaulesi kwambiri, zamadzimadzi zochepa poyerekeza ndi 304. Ngati khomo lanu ndi makina okwera apangidwa kuti azitsatira mawonekedwe a 304, mutha kukhala ndi zovuta kapena zocheperako m'magawo okhuthala ndi 304L. Ndi chinthu chobisika, koma chimakukakamizani kuti musinthe kachitidwe ndi ndondomekoyi. Tinaphunzira izi kumayambiriro, osati kuchokera m'buku lamanja, koma kuchokera kumagulu a ma valve omwe anayenera kuchotsedwa.
Ndiye pali pambuyo kuponyera kutentha mankhwala. Njira yothetsera vutoli ndiyofunikira, koma zenera la kutentha limakhala lolimba. Mukufuna kusungunula ma carbides aliwonse ndikubwezeretsanso ma chromium carbides kukhala yankho, koma simungathenso kukulitsa kwambiri. Timayendetsa pakati pa ° C, ndikutsatiridwa ndi kuzimitsa kofulumira. Sing'anga yozimitsa ikufunikanso. Madzi ndi aukali ndipo angayambitse kupotoza pazitsulo zovuta, zokhala ndi mipanda yopyapyala; nthawi zina timasankha kuzimitsa mpweya wokakamiza kuti tizigawo tolimba kwambiri. Ndi chigamulo chotengera gawo la geometry, chinthu chomwe mumamva pakapita nthawi.
Ndipo kuwotcherera? Zedi, ndizowotcherera kwambiri. Koma m'malo athu CNC makina ndi dipatimenti yomaliza, nthawi zambiri timapeza zigawo zomwe zimafunikira kukonza kapena kusonkhana. Chowotchereracho chikhoza kukhala chomveka, koma malo omwe amakhudzidwa ndi kutentha (HAZ) pa 304L, ngakhale osamva kukhudzidwa, amatha kusintha kusintha kwa microstructural komwe kumakhudza kukana kwa dzimbiri kwanuko ngati simusamala ndi kutentha kwa interpass. Ndi zabwino, koma sizingagonjetsedwe. Mukufunikirabe wowotcherera yemwe amamvetsetsa zakuthupi, osati njira yokhayo.
Machining 304L: The Gummy Reality
Apa ndi pamene chiphunzitso chimakumana ndi chida chodulira, nthawi zambiri ndi screech yokhumudwitsa. 304L ndi yodziwika bwino chifukwa cholimbikira ntchito. Ngati chida chanu sichili chakuthwa, ngati zakudya zanu ndi kuthamanga kwanu kuzimitsidwa, kapena mutakhala kwa kamphindi, mudzaumitsa pamwamba, ndikupangitsa kuti lotsatira likhale lovuta. Izo sizimamveka bwino; Zimakonda kupanga zingwe zazitali, zolimba zomwe zimakhala zowawa komanso zowopsa.
Takhazikitsa malamulo angapo mu shopu yathu. Positive rake geometry, popanda funso. Zovala zakuthwa, zokutira za carbide - takhala ndi zotsatira zabwino ndi zokutira za AlTiN. Nthawi zonse, chakudya chaukali. Simungakhale amantha; muyenera kulowa pansi pa wosanjikiza-olimba ntchito. Zoziziritsa ndizosakambirana, ndipo zambiri, osati kungozizira koma kuthandiza kuswa chip. Timathamanga kwambiri kuposa momwe mungapangire zitsulo za carbon carbon, koma ndi chakudya chambiri. Ndi ntchito yolinganiza yomwe mumasinthira pa ntchito iliyonse. Nyumba yamapampu yovuta yokhala ndi makoma owonda makina mosiyana ndi flange yolimba.
Choyipa kwambiri ndi pamene mupeza kuponyera ndi kuuma kosagwirizana. Nthawi zina, chifukwa cha kusinthasintha pang'ono kwa kuzizira kwa nkhungu, mutha kupeza mawanga omwe ndi ovuta kuposa ena. Chida chanu chikung'ung'udza, kenako chimangonjenjemera ndikuyaka. Muyenera kuyimitsa, kuyang'ana, mwinanso kusokoneza chidutswa chonsecho ngati chili choyipa. Ichi ndi chifukwa chimodzi chomwe kuwongolera njira kuyambira kusungunula mpaka kuchiritsa kutentha kuli kofunika kwambiri. Kampani ngati Mtengo wa QSY, ndi zaka zambiri chipolopolo nkhungu kuponyera ndi kuponya ndalama, imapanga chidziwitso cha bungwe mu kayendetsedwe ka ntchito kuti achepetse zosiyanazi, koma zodabwitsa zikuchitikabe.
Kuwonongeka: Ndi Za Chilengedwe, Osati Giredi Yokha
Ili ndiye lingaliro lolakwika kwambiri. Anthu amatchula 304L ya kukana dzimbiri ngati mawu ofunda. Koma dzimbiri zotani? Mumlengalenga? Zedi, ndi zabwino kwambiri. Kukhudzana ndi mankhwala pang'ono? Mwina zabwino. Koma ndawonapo zolephera m'malo enieni, oyipa.
Chloride ndiye adani akulu. Ngakhale kutentha kwambiri, ma chloride ayoni amatha kuyambitsa dzimbiri ndi ming'alu. Tidapereka zopangira 304L zopangira mizere yamadzi yomwe ili m'mphepete mwa nyanja. Adawoneka bwino kwa chaka, kenako adayamba kutuluka m'maenje a pinprick pansi pa misampha yotsekera komwe chinyezi chimasonkhanitsidwa. Zomwe zidalipo zinali zofotokozera, koma chilengedwe chinali cholakwika. Kuti muchite izi, muyenera kulumphira ku 316L ndi molybdenum. Phunziro silinali la khalidwe lachitsulo; zinali za uinjiniya wa ntchito.
Ndiye pali intergranular dzimbiri. Gulu la L limateteza ku kuwotcherera, koma ngati gawolo likugwiritsidwa ntchito mu 450-850 ° C kwa nthawi yayitali kwambiri panthawi ya utumiki-titi, pafupi ndi gwero la kutentha-chidziwitso chikhoza kuchitika pakapita nthawi. Ndi kulephera kwapang'onopang'ono. Muyenera kuganizira za moyo wonse wa chigawocho, osati momwe chimapangidwira.
The Alloy Nuance mu Multi-Material Shop
Kugwira ntchito m'malo ngati athu Mtengo wa QSY, kumene timachitira chilichonse chitsulo chachitsulo ku ma aloyi apadera monga zopangira faifi tambala, zimakupatsani mawonekedwe. 304L sikuwoneka payokha. Ndi gawo la sipekitiramu. Ubwino wake waukulu ndi mtengo komanso kupezeka kwanthawi zonse motsutsana ndi ma aloyi a nickel apamwamba. Koma malire ake amatanthauzira malo ake.
Mwachitsanzo, kasitomala akafuna kutentha kwambiri, timawachotsa pa 304L kupita kwathu zitsulo zopangidwa ndi nickel. Akafuna kukana dzimbiri kwambiri pakuchepetsa ma acid, mwina ndi nthawi yake ma aloyi opangidwa ndi cobalt. 304L imakhala pamalo okoma omwe amagwira ntchito bwino komanso kupangidwa kwazinthu zambiri zamafakitale - nyumba zamapampu, ma valve, zopangira chakudya, zida zamamangidwe. Ndi kavalo wantchito.
Koma ngakhale ngati kavalo, kufufuza zinthu kumafunika. Timatchera khutu ku chemistry yosungunuka. Sulfure yochulukirachulukira imatha kukulitsa luso la machina koma imavulaza kukana dzimbiri. Kulinganiza koyenera kwa silicon kumatha kupititsa patsogolo fluidity poponya. Ndizidziwitso zazing'ono zomwe zimasiyanitsa gulu lomwe makina ngati batala ndipo amakhala kwazaka zambiri kuchokera pa zomwe zimayambitsa mutu kuyambira tsiku loyamba.
Kumaliza Popanda Uta
Chifukwa chake, ayi, 304L sichinthu chabe. Ndizinthu zomwe ntchito zake zenizeni zimatsegulidwa (kapena zolepheretsedwa) mwatsatanetsatane wa ndondomekoyi. Pamapeto pa tsiku, kuchita bwino kwa gawo la 304L kumadalira momwe amapangira, luso la makina, komanso momwe amapangira chilengedwe monga momwe amachitira pamsonkhano wa chemistry ASTM A743. Ndi mgwirizano pakati pa zinthu ndi wopanga. Simungathe kungoyitanitsa kuchokera m'katalogu ndikuyembekezera ungwiro. Muyenera kumvetsetsa umunthu wake, zizolowezi zake, ndi kulemekeza malire ake. Izi ndi zimene zaka makumi atatu za kuponya ndi kupanga makina zikukuphunzitsani—kuona zitsulo, osati nambala chabe.
