Mayankho a fakitale ya zitsulo zosapanga dzimbiri za Austenitic ayenera kupereka zambiri kuposa kungotsatira zakuthupi-ayenera kutsimikizira kukana kwa dzimbiri komwe kupulumuka ntchito zenizeni zapadziko lonse lapansi: kuwonekera kwa ma chloride ambiri m'ma hydraulics akunyanja, kupalasa njinga zotenthetsera m'nyumba zopopera, kapena kukhudzana ndi abrasive slurry mu makina a winch yamagalimoto. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga zida zopitilira 12,000 za austenitic zosapanga dzimbiri za mavavu opanikizika ndi ma silinda a pisitoni kuyambira 2019-ndipo kusanthula kulikonse kolephera kunatiphunzitsa chinthu chimodzi: kukana dzimbiri sikuwotchedwa m'kalasi. Zimapangidwa mu ndondomeko ya ndondomeko.
Kukaniza kwa Corrosion Kumayamba Asanayambe Machining - Osati Pambuyo
Ogula ambiri amaganiza kuti ASTM A351 CF8M kapena UNS S31603 imangofanana ndi "umboni wa corrosion." Iwo akulakwitsa. Tawona kuponyedwa kofananako kukulephera m'malo ofanana amadzi a m'nyanja - imodzi idadutsa kuyesa kwa kupopera mchere kwa maola 2,000; wina adakhala mkati mwa maola 72. Choyambitsa? Osati kupatuka kwa chemistry-koma kulimba kosagwirizana pakuponya mchenga. Kugawikana kwapang'ono komweko kudapanga madera opanda chromium m'malire a interdendritic. Kukonzekera sikunali kuyambiranso. Anali kukonzanso makina olowera, kuwonjezera mbale zoziziritsa kukhosi, ndikusunga kutentha kwazitsulo zamadzimadzi mkati mwa ± 5 ° C panthawi yothira. Umu ndi momwe timagwirizira nambala ya ferrite pakati pa 5–8 FN pakupanga kulikonse kwa CF8M—kutsimikiziridwa ndi kafukufuku wa maginito *pasanathe* chithandizo cha kutentha, osati pambuyo pake.
Sitimapereka zitsulo kunja. Zolemba zathu zopangira zinthu zimatsata kutentha kulikonse kupita ku malipoti a mill test (MTRs) zowonetsa zenizeni za Cr, Mo, Ni, ndi N - osati "zokumana nazo." Pazinthu zovuta kwambiri monga AMS 5387 cobalt alloy alloy pampu zomwe zimagwira ntchito motsatira ma austenitic housings, timatsimikizira kuyenderana kwa galvanic kudzera mumiyezo yotseguka yopezeka m'ma electrolyte oyeserera. Ngati kusiyana komwe kungathe kupitilira 50 mV, timasintha magawo apansi - ngakhale alloy yoyambira ndi "yolondola."
Komwe Zofuna Zambiri za Austenitic Stainless Steel Factory Zimaphwanya
Otsatsa ena amapeza malo ovomerezeka a "ISO-certified" pomwe akugwiritsa ntchito ma calipers am'manja powunika komaliza zolemba za 0.005 mm tolerance shaft. Sititero. Chigawo chilichonse chachitsulo chosapanga dzimbiri chochokera ku Qingdao chimayang'aniridwa katatu:
- Kutsimikizira kukhulupirika kwapamwamba: Kuphatikizika kwa kuwala koyera pankhope zomata, osati kukhadzula kokha (Ra) - chifukwa malo osalala ong'ambika amapangitsa kuti zimbiri ziwonongeke.
- Kutsimikizira kosanjikiza: Electrochemical impedance spectroscopy (EIS), osati kuyesa kwa nitric acid dip-chotero timayesa makulidwe a oxide ndi kachulukidwe kachilema, osati kusintha kwa mtundu
- Mapu otsalira opsinjika: Kusiyanitsa kwa X-ray pa malo ovuta a 5 pa gawo lililonse, makamaka pafupi ndi minofu ndi ulusi-popeza kupanikizika kwamphamvu pamwamba pa 200 MPa kumathandizira SCC m'madera a chloride
One European hydraulic OEM idakana kutumiza kwathu koyamba kwa maziko a mpope a S31603 - osati chifukwa cha zolakwika zazikulu, koma chifukwa cha kupsinjika kotsalira pafupi ndi mabowo omangika. Tidayankha ndi mamapu opsinjika, kenaka tidakonzanso zomangira ndikuwonjezera kugwedera kochepetsa nkhawa tisanapange makina omaliza. Kutumiza kunatsika milungu iwiri. Moyo wa dzimbiri unapitilira miyezi 18 mpaka 47 m'mayesero akumunda. Ndiko kusinthanitsa kopanda ziwonetsero.
Zochitika Zenizeni Padziko Lonse Zimafuna Kumaliza Kwapadziko Lonse
Machining marks ndizofunikira. Mapeto a 0.8 µm Ra akhoza kukumana ndi zojambulazo-koma ngati zizindikirozo ziyenderana ndi njira yoyendetsera ma valve, zimakhala malo oyambitsa dzimbiri. Timawongolera njira zoyendera kuti zigwirizane ndi kutsitsa kwa ntchito: zozungulira zozungulira ma shafts, axial for static housings, ndi blended radii pakusintha. Pazigawo za T800 za cobalt zomwe zimawotcherera mumisonkhano ya austenitic, timayika kuwotcherera kwa electropolishing * pambuyo * - osati kale - kuchotsa ma zone oxides omwe amakhudzidwa ndi kutentha popanda kutsitsa chala chowotcherera.
Kukwezera kwathu komwe tikufuna kwambiri? Passivation ndi citric acid + sodium nitrate m'malo mwa chikhalidwe nitric acid. Chifukwa chiyani? Chifukwa citric acid imachotsa chitsulo chaulere popanda kusungunula chromium-chofunikira kwambiri popanga magawo osakanizidwa a duplex-austenitic. Timatsimikizira zotsatira ndi kuyesa kwa copper sulfate * ndi* ferroxyl indicator solution, kuyang'ana zonse zaukhondo wapamtunda ndi kufanana kwa mafilimu. Makasitomala amafotokoza 3.2 × zolephera zochepa pakuyika m'mphepete mwa nyanja mutasintha.
Kusankha Austenitic Stainless Steel Factory Kumatanthauza Kusankha Wothandizira Njira
Ngati ntchito yanu ikukhudza kuthamanga kwa cyclic, kutentha kokwezeka, kapena kukhudzana ndi zinthu zosiyanasiyana, gawo lazinthu ndi sitepe imodzi yokha. Khwerero 2 ndikutsimikizira momwe wogulitsa amawongolera tsankho, kupsinjika, komanso mawonekedwe amtundu uliwonse. Khwerero 3 ndikutsimikizira kuti QA yawo siyiyima pamayendedwe amtundu - imayesa machitidwe a electrochemical, microstructural homogeneity, ndi moyo wautali wogwira ntchito.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito ngati chowonjezera cha gulu lanu la uinjiniya-osati ogulitsa magawo. Timawunikiranso ma callouts a GD&T kuti apangitse kukana kwa dzimbiri. Timayimilira maanja omwe atha kukhala osagwirizana tisanayambe kuyimba. Timasunga kutsata kwazinthu zonse mpaka nambala ya ladle ndi chipika chozungulira cha kutentha. Ndipo dzimbiri zikawoneka, sititumiza zina - timatumiza lipoti lazoyambitsa ndi zitsulo ndi ma protocol okonzanso.
Kukana kodalirika kwa dzimbiri sikutsimikiziridwa ndi kalasi. Zimapezedwa m'malo opezekapo, zotsimikiziridwa mu labu, ndipo zimatsimikiziridwa m'munda. Ndiwo muyezo fakitale iliyonse yazitsulo zosapanga dzimbiri ya austenitic iyenera kukwaniritsa-koma ochepa amatero.
