Imvula eqina izisombululo zefektri yensimbi engenasici zifuna okungaphezulu nje kokwazi kwe-metallurgical-zifuna ulawulo oludibeneyo malunga nokuziphatha kwezinto eziphathekayo, ukuzinza kwe-dimensional, kunye nokuthembeka okusebenzayo phantsi kweemeko zenkonzo ezigqithisileyo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sivelise ngaphezulu kwe-12,000 yamacandelo achanekileyo kwiintsimbi ze-PH-ezibandakanya i-17-4PH, i-15-5PH, kunye ne-AMS eguquliweyo ye-5659 amabakala-kwimizimba yevalve ye-hydraulic, i-high-pressure pumps wins Yintoni eyahlula isisombululo esisebenzayo ekungaphumeleli kweendleko ayikokukhetha i-alloy yodwa-yindlela yokuphosa ingqibelelo, ukuphindaphinda unyango lobushushu, kunye ne-multi-axis machining idibana kwinqanaba lenxalenye.
Kutheni iMveliso yeStainless Steel ye-PH isilela phantsi koMthwalo wokwenyani weHlabathi
Siye sabona iindlela ezintathu zokungaphumeleli eziphindaphindiweyo kwiindawo ze-PH ezibonelelwa ngabathengi: i-microcracking emva kokwaluphala, ubunzima obungahambelaniyo kuwo wonke amacandelo anodonga oluncinci, kunye ne-galling engaphambi kwexesha kwiindawo ezijikelezayo. Ezi ayizizo iziphene eziphathekayo-zizithuba zenkqubo. Ngokomzekelo, enye impompo yaseYurophu i-OEM ibike i-22% ye-scrap kwi-17-4PH i-cylinder liners ngexesha lokugqibela lokuguga kwe-H900. Uhlalutyo lwethu lwengcambu lubonakalise ukuhamba komoya okungalinganiyo kwesithando somlilo kwi-oven yabo ye-batch-ebangela i-± 8 ° C i-thermal gradients kuwo wonke umthwalo. Siyilungisile ngokutshintshela kwi-vacuum-assisted aging kunye ne-real-time thermocouple mapping kwi-fixture nganye. Isiphumo: ukuhluka kobunzima kwehla ukusuka kwi-± 12 HRC ukuya kwi-± 3 HRC; isivuno siye saphucuka ukusuka kuma-71% ukuya kuma-98.4%.
Loo mava asifundisa isifundo esibalulekileyo: ukuqina kwemvula ayilonyango “lokuseta-nokulibaleka” lobushushu. Lulandelelwano oludityanisiweyo oluqinileyo-isisombululo se-annealing lokushisa kufuneka sibambe ngaphakathi kwe-± 5 ° C, izinga lokucima kufuneka lidlule i-50 ° C / sec ukucinezela ukubunjwa kwe-delta-ferrite, kunye nexesha lokuguga / lobushushu kufuneka lihambelane ngokuchanekileyo kunye nesigaba sokuhamba kwethagethi (umzekelo, i-Cu-rich clusters ye-50-4PH ye-Custom 17-4PH ye-Ni. Phambuka nangemizuzu eyi-10 kwi-480 ° C, kwaye uncama i-15-20% yamandla okuqina ngaphandle kotshintsho olubonakalayo.
Indlela uHlanganiso oluthe nkqo oluSombulula ngayo i-PH iNgxaki yokuNxibelelana kweSimbi eStainless
Uninzi lwababoneleli abakhuphela ngaphandle, unyango lobushushu, kunye nomatshini-inyathelo ngalinye longeza ikhefu lokulandela umkhondo kunye nokukhukuliseka okulinganayo. Senza zonke zontathu endlwini, phantsi kwe-ISO 9001: uphahla oluqinisekisiweyo lwe-2015 eQingdao. Xa umxhasi we-oilfield yaseMntla Melika efuna i-15-5PH i-piston rod blanks nge-≤0.02mm cylindricity ngaphezu kwe-450mm ubude, iqela lethu le-sand-casting lisebenzisa ii-molds ze-ZrO₂-bonded ukuphumeza uburhabaxa be-Ra 3.2μm-ukusika ukususwa kwe-stock post-machining nge-40%. Emva koko iziko lethu le-CNC lasebenzisa iindlela eziguquguqukayo ezihlawulela ukwahluka kwe-shrinkage yendawo efunyenwe ngokuskena kwangaphambili kweCMM. Okokugqibela, iseli yethu yokuphatha ubushushu yaguga iqashiso ngalinye ngokugawulwa kwe-thermocouple-enokulandelelwa kwinombolo yobushushu obukrwada kunye ne-ID yomjikelo wesithando somlilo.
Oku asikokudityaniswa kwethiyori. Lulawulo olunokumetwa:
- Ukulandeleka kwezinto eziphathekayo ukusuka kwisatifikethi se-ingot ukuya kwingxelo yenxalenye egqityiweyo
- Idimensional drift ibanjwe ukuya ku ≤0.015mm ngapha kwe 100-part iibhetshi
- Ubulukhuni bemigangatho yokuguga buncitshisiwe ukusuka kwi-4.7 HRC ukuya kwi-1.3 HRC
- Ukugqitywa komphezulu kugcinwe kwi-Ra 0.4μm ebusweni bokutywinwa okubalulekileyo
Apho i-PH iStainless Steel idibana noMsebenzi-oBalulekileyo
Abathengi abathengi i-PH yentsimbi engatyiwa-bathenga isiqulatho soxinzelelo esingavuziyo, impendulo yevalvu yentonga enguziro, okanye ubomi beshafu obungadinwa. Yiyo loo nto sibethelela ukuqinisekiswa okusebenzayo kuyo yonke iodolo. Kwi-AMS 5387 cobalt-alloy nozzle edityaniswe ne-17-4PH yokufaka i-flange, asiqinisekisi nje i-chemistry kunye namandla okuqina. Siqhuba i-500-cycle thermal cycling phakathi kwe -40 ° C kunye +180 ° C, emva koko sihlolisise i-microseparation ye-interfacial microseparation usebenzisa i-ultrasonic C-scan. Sivavanya ukutyibilika kobuso betywina phantsi kokulinganisa komthwalo osebenzayo-hayi nje kubushushu be-ambient. Kwaye kwi-winch center shaft rollers, siqinisekisa ukuqina kwe-torsional ngokuchasene neprofayili ye-torque eguqukayo efakwe kwiiyunithi zentsimi.
Le lens esebenzayo itshintsha yonke into. Umthengi wakha wacela "umgangatho we-17-4PH" wevalve yokuzahlula engaphantsi kolwandle. Uphononongo lwethu lobunjineli lubonise ukuba umsindo we-H1025 ochaziweyo awuyi kusinda ekugobeni kwi-3,000 yeemitha zamanzi. Sicebise umjikelo wokuguga oguqulwe kabini (1025 ° F × 4h → umoya opholileyo → 900 ° F × 4h) onyuse ukuqina kwe-fracture nge-37% ngelixa igcina > 1,200 MPa UTS. Baluvuma olo tshintsho—baza bandisa ixesha labo lokulondoloza ukusuka kwiinyanga ezili-18 ukusa kwezingama-36.
Ukukhetha i-Precipitation yakho Ukwenza lukhuni i-Stainless Steel Factory Partner
Ukuba isicelo sakho siquka ukukhwela ibhayisekile ngoxinzelelo, ukuba sesichengeni samanzi etyuwa, okanye ukunxitywa okujikelezayo, i-PH insimbi engenasici inokuba yeyona ndlela inamandla-kodwa kuphela ukuba iqabane lakho lasefektri lilawula ikhonkco elipheleleyo. Buza le mibuzo phambi kokuba utyikitye i-PO:
- Ngaba ungandibonisa amaphepha elogi onyango lobushushu kwiiqashiso ezintathu zakutsha nje ze-17-4PH, kubandakanya nezikhundla ze-thermocouple kunye nerempu yerempu?
- Ngaba uyayenza inkqubo yokuqinisekisa iCMM emva kokurhabaxa-kwaye uhlengahlengise iindlela zesixhobo ngokufanelekileyo?
- Ngowuphi umahluko onzima wobunzima bakho kwi-15-5PH yokuphosa enobunzima > 80 kg?
- Ukuqinisekisa njani ukuxhathisa umhlwa kwiindibano ze-PH ezidityanisiweyo?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uphendula loo mibuzo ngedatha—hayi iincwadana. Sipapasha iingxelo zekota zokusebenza kwesinyithi kwiintsapho ezingenastainless ze-PH kwiphothali yethu yobugcisa. Sinikezela ngenkqubo yokufaneleka yenkqubo edibeneyo yokwamkelwa kwenqaku lokuqala. Kwaye siqulunqa izicwangciso zokuhlola ezihambelana ne-ASME BPVC iCandelo VIII, i-API 6A, okanye i-ISO 15156-nayiphi na esebenzayo kwinkqubo yakho.
Ikamva lemvula eqinisa amandla efektri yentsimbi engasebenziyo alikho kwiziko ezikhulu okanye kwiispindles ezikhawulezayo-kodwa kwiilophu eziqina phakathi kwenjongo yoyilo, ulawulo lwemicrostructure, kunye nokusebenza endle. Kulapho sigxininisa khona. Yiloo nto ehambisa iinxalenye ezingadibaniyo nee-specs-kodwa ziphila ngaphandle kwazo.
