Kana mainjiniya akatsanangura simbi isina tsvina ye hydraulic mavharuvhu, pombi dzimba, kana offshore winch shafts, ivo havangodi simbi-vanoda dimensional kugadzikana pasi pe 300 bar, corrosion resistance munzvimbo dzine chloride-laden, uye microstructural integrity mushure mekurapwa kwekupisa. Ndicho chikonzero an investment kukanda Stainless simbi fekitari haisi mutengesi-iyo yekuwedzera tekinoroji yechikwata chekugadzira.
Isu takaona mapurojekiti akawandisa achimira padanho remuenzaniso nekuti muvambi waibata simbi isina tsvina senge kabhoni simbi: geji rakafanana, mwero wekutonhora wakafanana, protocol yekuongorora yakafanana. Asi 316 isina tsvina inodzika 12% kupfuura simbi yakakandwa panguva yekusimba. Thermal conductivity yayo ihafu yearuminiyamu. Uye iyo yepamusoro oxide layer-yakakosha papassivation-inoumbwa chete kana kutonhora kunotevera chaiyo 5-10°C/min hwindo post-casting. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata simbi yega yega yekukandira mari sechiitiko chesimbi-kwete maitiro ekugadzira chimiro.
Precision Inotanga Mold Isati Yadururwa
Vatengi vazhinji vanofungidzira mari yekukanda kurongeka kunobva kuceramic shell thickness control. Hazvidaro. Inotanga newakisi pateni geometry-uye kuti iyo geometry inodyidzana sei nealloy shrinkage. Semuenzaniso: piston pombi silinda imba yakagadzirwa kubva kuASTM A473 Giredhi 316 inofanirwa kubata ± 0.05 mm paBore ID kuyambuka 280 mm kureba. Izvi tinozvikwanisa nekuenzanisa kuwedzera wakisi kumirisana nekumisikidza kwearoyi yekupedzisira tichishandisa in-house thermal simulation-kwete machati egeneric. Chikwata chedu chekushandisa chinogadzirisa maekiseni ekudhirowa ne 0.15 ° increments zvichienderana nemadziro ukobvu gradients, kwete akajairwa matemplate. Isu takasimbisa nzira iyi mhiri kwe172 kugadzirwa kwemagetsi ekumanikidza mavharuvhu; 99.4% yakapasa yekutanga-chinyorwa CMM verification pasina rework.
Iyi nhanho yekutonga inoda kubatanidzwa kwakatwasuka. Isu hatibudise chivakwa chegomba, dewaxing, kana kudzora kwechoto. Yedu ISO-inoenderana nzvimbo inobata ese ari matatu-uye anozvibatanidza kune chaiyo-nguva thermocouple data kubva kune yega yega crucible. Kana ichinyunguduka 316 isina tsvina, isu tinoongorora yakanyungudika okisijeni yemukati nguva dzose. Kupfuura 25 ppm? Iyo batch inokonzeresa otomatiki diversion kune isiri-yakakosha maapplication. Hapana kunze.
Iko Cobalt Alloys uye Stainless Simbi Zvinosangana
Hezvino izvo zvinorasikirwa nezvikwata zvakawanda zvekutenga: simbi isina tsvina yekukandira haina kuparadzaniswa nebasa repamusoro. Panzvimbo yedu, vira rimwe chete rinopisa AMS 5387 cobalt alloy uye CF8M isina tsvina. Sei? Nekuti ese ari maviri anoda zvakafanana kudzora kwemuchadenga (vacuum + argon backfill), yakafanana mold preheat ramps (120 ° C/h kusvika 1,100 ° C), uye akafanana shakeout nguva windows (± 90 masekonzi). Uku kurangwa kwemuchinjika kunoreva kukanda kwedu zvisina tsvina kugara nhaka yakasimbiswa yekupisa manejimendi - hapana kuedza-uye-kukanganisa kudzidza macurves.
Tora T800-yakavakirwa pombi zvikamu. Kuomarara kwavo (42–48 HRC) kunoda kugadziriswa kwemvura pa1,120°C kuchiteverwa nekudzimwa kwemvura mukati memasekondi makumi mana nemashanu. Isu takagadzira iyo yekudzima tambo mumutsara wekukanda-kwete sekufunga kwekupedzisira. Mhedzisiro: zero kukanganisa pa142 mm-diameter impeller hubs uko vatengesi vekare vakashuma 0.18 mm kubuda.
- Mavharuvhu ekumanikidza: ASME B16.34 Kirasi 600, yakasimbiswa kuNACE MR0175/ISO 15156
- Piston pombi cylinder housings: GD&T-inoenderana neASME Y14.5-2018, kusanganisira chimiro chezvinodzora zvepasi zvemating flanges.
- Injiniya mota winch centre shaft rollers: Kuoma kwakasimbiswa paASTM E10, kupera kwepamusoro Ra ≤0.8 µm sekukanda
- Cobalt alloy nozzles: Dimensional kugadzikana kwakasimbiswa mushure memazana mashanu ekudziya kutenderera pakati -40 ° C uye +220 ° C.
Nei "Certified Raw Materials" Haisi Kungotengesa
"Isu tinoshandisa certified stainless simbi" inoonekwa pa83% yemawebhusaiti evatengesi. Asi chitupa hachirevi chinhu kana traceability yakamira pacoil tag. Panzvimbo yedu, nhamba yese yekupisa inoyerera yakananga mune yedu ERP system-uye mepu kune chaiyo castings kuburikidza nelaser-etched lot kodhi pachikamu chese. Kana mutengi akakumbira zvizere pedigree ye subsea valve odha, takaendesa mill test mishumo, spectrographic analysis logs, uye choto soak-nguva marekodhi - zvese zvakasungirirwa kune ega manhamba ekukanda. Iyo nhanho yekubuda pachena haisi sarudzo. Inodiwa kuti API 6A itevedzere-uye yakabikwa mukufamba kwedu, isina kuvharirwa pakuongorora.
Isu tinobva 316, 304L, uye duplex 2205 chete kubva kumagayo ane EN 10204 3.1 certification-uye tinoona chemistry kana tatambira tichishandisa handheld LIBS spectrometry. Kana chromium ikawira pasi pe16.5% mumuenzaniso we304L, coil yese inovharirwa isati yaturwa. Hapana kunze. Kwete "iyi kamwe chete."
Kutengeswa Kwechokwadi Kunoreva Kufanotaura Kwechokwadi
Bvunza vatengesi vashanu kuti uwane nguva yekutungamira pakudyara kwesimbi isina tsvina, uye iwe uchawana mhinduro shanu-ine mitsara inotora mavhiki masere kusvika makumi maviri nemaviri. Yedu yakagadziriswa: mavhiki e14 ekutanga chinyorwa, mavhiki gumi ekudzokorora mirairo-yakavimbiswa. Sei? Nekuvhara simba kare: 30% yezviteshi zvedu zvekuvaka magoko zvakachengeterwa matani-chaiwo mapatani, uye yedu vacuum induction furnaces inoronga kupisa kusina tsvina mumabhuraki akazvitsaurira evhiki. Hapana kuchinjanisa alloys pakati pekumhanya. Hapana njodzi yekusvibiswa. Hapana kunonoka kunoshamisa kubva kune zvakagovaniswa zviwanikwa.
Tinosimbisa vimbiso iyi zuva nezuva. Chikamu chekupedzisira, 97.2% yemirairo yesimbi isina tsvina yakatumirwa pazuva kana risati raitwa. Iyo 2.8% musiyano? Zvese zvakatevedzwa kune mutengi-akakumbirwa shanduko yeinjiniya mushure mekubvumidzwa kwechishandiso-kwete kutadza kwemukati mekuita.
Kana purojekiti yako inotevera ichida mumwe wako anobata simbi isina tsvina yekukandira sesimbi, kwete kugadzira-iwe unoda investment kukanda Stainless simbi fekitari yakavakirwa nemazvo, kwete vhoriyamu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda nenzira iyoyo-kwete nekuti yakanakira, asi nekuti yakanyanya-kudzvanywa, yakanyanya-corrosion, yakakwirira-yakavimbika zvikumbiro zvinosiya pasina nzvimbo yekukanganisa. Precision harisi dhipatimendi pano. Ndiyo inoshanda sisitimu.
