Pamene mainjiniya afotokoza 316 kapena 316L chitsulo chosapanga dzimbiri pazigawo zofunika kwambiri - ma valve opanikizika m'ma hydraulic systems a m'mphepete mwa nyanja, nyumba za silinda za mapampu a pistoni othamanga kwambiri, kapena zodzigudubuza za winch center shaft pamagalimoto a engineering - iwo samangosankha zinthu. Akusankha chitsimikiziro cha magwiridwe antchito: kukana kutsekereza kopangidwa ndi kloridi, kukhazikika kwapangidwe pamatenthedwe okwera, komanso kukhulupirika kwanthawi yayitali m'malo owopsa amankhwala. Koma chitsimikiziro chimenecho chimangogwira ngati fakitale yopereka gawoyo ikuchita zinthu zitatu: kusasinthika kwazitsulo, kukhulupirika kowoneka bwino pansi paulamuliro wolimba wa GD&T, ndi kulekerera zero pakusuntha kwazinthu.
Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni 316 316L fakitale yachitsulo chosapanga dzimbiri nkhani-osati wopereka zitsulo wamba, osati kampani yogulitsa masking ngati wopanga, koma malo omwe kutentha kulikonse kwa 316L kumatsatiridwa ndi malipoti ovomerezeka a mphero, pomwe ma CNC machining magawo amawunikidwa makamaka kwa mawonekedwe a austenitic stainless flow, ndi komwe kuponyera porosity kumagwidwa musanayambe kutentha komaliza - osati pambuyo.
Tawona mapulojekiti ambiri akuchedwa chifukwa "wopereka zitsulo zosapanga dzimbiri" adavomereza zojambula popanda kuyika chizindikiro kuti maziko a mpope a 316L omwe amakhala ndi mipanda yopyapyala amatha kupindika panthawi yochepetsera nkhawa pokhapokha atapangidwa motsatizana ndi mphamvu yokhotakhota. Tayesa ma nozzles a AMS 5387 cobalt alloy mbali ndi mbali ndi ofanana ndi 316L m'mayendedwe oyeserera amadzi a m'nyanja - ndipo tidayang'ana kukhazikika komwe njira zotsika mtengo zidalephera maola 2,800. Umenewo si chidziwitso chanthanthi. Zimapangidwa m'zida zathu, ndondomeko zathu zoyendera, ndi momwe timawerengera kafukufuku aliyense wa CMM tisanayeze kutha kwa mpando wa valve 316L.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kulondola sikunakhazikitsidwe pamwamba pazopanga - kumapangidwira. Malo athu ogwirizana ndi ISO ku Qingdao amasamalira zitsulo zosapanga dzimbiri komanso mchenga wa 316/316L, kenako amamaliza ndi makina a CNC amitundu yambiri omwe amasunga ± 0.01 mm kulolerana pazinthu monga malo osindikizira ndi ma bolt-bolt mapatani. Sitimapereka chithandizo cha kutentha kunja. Sitikuvomereza ma billets osatsimikiziridwa. Zida zilizonse zopangira zida zonse zimawunikiridwa pofika - ndipo kutsatiridwa kwathunthu kumayikidwa mu dongosolo lathu la ERP mpaka nambala ya ng'anjo ndi kuzizira.
- Kuwongolera zinthu kumayamba musanadulire: Timapeza 316L kuchokera ku mphero zovomerezeka kupita ku ASTM A240/A484, zomwe zili ndi Mo zomwe zili pakati pa 2.0-3.0% ndi carbon ≤0.03% -zitsimikiziridwa pa kutentha, osati pa kutumiza.
- Machining amapewa kulimbikira ntchito: Timagwiritsa ntchito njira zotsika-RPM, zowonjezera zakudya zokhala ndi zida za PVD zophimbidwa ndi carbide zopangidwira austenitic zosapanga dzimbiri, kuchepetsa kutentha kwa kutentha ndi kusunga kukana kwa dzimbiri pamtunda.
- Kukhulupirika kwapamwamba sikungakambirane: Pazinyumba zapampu zokhala ndi brine, timayika passivation pa ASTM A967 (Njira B) ndikutsimikizira ma ratios a Cr/Fe ndi XRF—palibe macheke ongowona okha.
- Kutsimikizika kwa dimensional kumachitika katatu: pre-machining (kutsimikizira masheya), ndondomeko yapakatikati (madatum ovuta), ndi kumaliza pambuyo (kujambula kwathunthu kwa CMM motsutsana ndi mtundu wa CAD).
Ena anganene kuti malo aliwonse ovomerezeka a ISO amatha kupanga 316L. Koma kuponya 316L sikuli ngati kuponya chitsulo chotuwa. Kuchuluka kwake kwa nickel ndi molybdenum kumawonjezera chiopsezo cha kung'ambika. Kutsika kwake kwamafuta kumafuna kuwongolera bwino kwa nkhungu preheat. Ndipo chizolowezi chake chopanga gawo la sigma pakuzizira pang'onopang'ono kumatanthauza kuti ndondomeko zochizira kutentha ziyenera kutsimikiziridwa - osaganiziridwa. Tasiya kutentha kwamitundu iwiri chifukwa kuzizira kunagwera kunja kwa zenera la 5 ° C/mphindi lomwe likufunika kuti tipewe kuwonongeka. Ndiwo mtengo wodumpha chilango cha metallurgical.
Mphamvu zathu zagona pakuphatikizana koyima: kuponyera, kukonza makina, chithandizo cha kutentha, ndi kutsirizitsa kumachitika pansi pa denga limodzi, ndi miyezo yogawana ma metrology ndi malingaliro a nthawi yeniyeni pakati pa madipatimenti. Makasitomala akatumiza chojambula cha valavu yamagetsi ya 316L yosakhazikika yokhala ndi ma asymmetric kuzizirira, gulu lathu silimangotchula mtengo ndi nthawi yotsogolera. Timayendetsa kayeseleledwe kolimba, timapereka ma tweaks ang'onoang'ono a geometry kuti achepetse zibowo, ndikupangira makina otsatizana omwe amachepetsa kuwongoleranso-kudula nthawi yozungulira ndi 22% popanda kusiya kukhazikika.
Makasitomala apadziko lonse lapansi - kuchokera ku ma hydraulic OEMs ku Germany kupita kwa othandizira mafuta ku Texas - amadalira ife chifukwa kudalirika sikufuna malonda pano. Ndizotheka kuyeza: 99.4% yopereka munthawi yake m'miyezi 18 yapitayi, kulephera kwa zero komwe kumalumikizidwa ndi kusagwirizana ndi zinthu, komanso kukonzekera kwathunthu kwa ASME BPVC Gawo II kapena zolemba za PED 2014/68/EU. Timatumiza zida za 316 ndi 316L zosapanga dzimbiri ku North America, Europe, ndi Southeast Asia-osati ngati zinthu, koma monga zolembedwa, zotsatirika, zovomerezeka.
Ngati mukufuna a 316 316L fakitale yachitsulo chosapanga dzimbiri zomwe zimagwira gawo lanu ngati zida zofunika kwambiri - osati SKU yamtengo wapatali - mufunika abwenzi omwe apanga mazana a ma silinda a 316L a mapampu amatope atatu, omwe amamvetsetsa chifukwa chomwe mbali ya 0.5 ° yojambula imakhala yofunika kwambiri kuposa kuuma kwapampando wa valve yamadzi am'nyanja, komanso omwe amasunga ma certs osungidwa pafupi ndi chilichonse. Izi sizochita zokhazikika. Ndi ntchito yathu ya tsiku ndi tsiku.
Yang'anani m'tsogolo: tikukulitsa luso lathu pakupanga makina osakanizidwa amitundu yayikulu ya 316L ndikuzama R&D panjira yotsika kutentha kwapakatikati kuti muzitha kupirira dzimbiri. Chifukwa m'mafakitale apamwamba kwambiri, gawo loyenera lachitsulo chosapanga dzimbiri silimangopangidwa. Amapezedwa—mgulu ndi mtanda, kutentha ndi kutentha, kuyeza ndi kuyeza.
