Thaum lub twj tso kua mis hydraulic tsis ua haujlwm nyob rau hauv cov roj av ntug dej hiav txwv - los yog lub winch ncej seizes hauv lub mining excavator - lub hauv paus ua rau tsis tshua muaj tsim. Nws hnav. Thiab tsis yog ib qho hnav xwb: micro-abrasion, galling, thermal qaug zog hauv qab 300 ° C cyclic loads. Qhov ntawd yog qhov twg Stellite 6 qhov chaw Hoobkas muaj peev xwm nres yog xaiv tau. Nws dhau los ua qhov sib txawv ntawm 8,000 teev ntawm kev pabcuam thiab kev ua haujlwm tsis zoo.
Peb tau nrum Stellite 6 nozzles rau high-pressure acid txhaj tshuab nyob rau hauv Saudi Arabia - thiab saib lawv outlast peb tiam ntawm tus qauv stainless hloov. Peb tau machined AMS 5387 piston twj tso kua mis lub tog raj kheej vaj tse rau German OEMs uas tau thov ± 0.015 hli roundness ntawm 200 hli txoj kab uas hla, nrog nto tiav Ra ≤0.4 µm tom qab sib tsoo zaum kawg. Cov no tsis yog theoretical specs. Lawv yog cov qauv ntsuas txhua hnub hauv peb qhov ISO-certified foundry thiab machining chaw hauv Qingdao.
Stellite 6 tsis yog "tsuas yog lwm yam cobalt alloy." Nws muaj pes tsawg leeg - kwv yees li 65% Co, 28% Cr, 4% W, ntxiv rau Ni, Fe, thiab C - tsim cov matrix ntawm hard chromium carbides embedded nyob rau hauv ib tug tawv cobalt solid tov. Qhov ntawd ua rau nws tsis sib haum xeeb rau cov hlau-rau-hlau galling, corrosion nyob rau hauv chloride-nplua nuj ib puag ncig, thiab thermal softening mus txog 500 ° C. Tab sis ntawm no yog qhov feem ntau buyers overlook: casting Stellite 6 tsis zoo li cov hlau casting. Nws lub siab melting point (1,290–1,350 ° C), fluidity tsawg, thiab huab shrinkage xav tau tshwj xeeb rooj vag, meej pwm preheat tswj, thiab tom qab-cam khwb cia homogenization tshav kub kho. Hla ib kauj ruam - thiab koj tau txais porosity, carbide cais, los yog nkig interdendritic theem. Peb tau pom cov neeg siv khoom tsis lees paub 40% ntawm thawj pawg castings los ntawm cov neeg muag khoom tsis tsim nyog. Peb cov txiaj ntsig ntawm txoj kev Stellite 6 peev castings khiav ntawm 92% + vim tias peb tswj txhua qhov sib txawv: cov ntaub ntawv pov thawj raw khoom (tag nrho T800-qib cobalt alloys traceable rau zeb xeem ntawv qhia), nqus-melted ingot nrhiav, thiab real-time thermal profiling thaum solidification.
Vertical kev koom ua ke cais kev txhim khu kev qha Stellite 6 qhov chaw tsim khoom los ntawm cov neeg muag khoom. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., casting, CNC machining, thiab ua tiav tshwm sim nyob rau hauv ib lub ru tsev-nrog kev sib koom ua ke, kev sib koom ua ke GD&T kev txhais lus, thiab xoom xa tawm qeeb. Thaum tus neeg siv khoom xa daim duab kos rau cov tsis yog qauv cobalt alloy plug nrog asymmetric txias raws thiab 0.008 hli tso cai kam rau ua rau tsib threaded nta, peb tsis outsource qhov tig. Peb khiav nws ntawm peb 5-axis DMG MORI NTX 1000, siv PCD-tipped cov cuab yeej optimized rau cobalt alloys, nrog in-process laser probing los xyuas cov phab ntsa thickness ua ntej zaum kawg ID sib tsoo. Tsis muaj tus neeg muag khoom sab nraud nkag siab tias qhov kev ntxhov siab seem ntawm kev ua haujlwm li cas cuam tshuam rau machining distortion ntawm 320 mm ntev valve lub cev. Peb ua-vim peb nrum nws, kho nws, tshuab nws, thiab tshuaj xyuas nws nrog tib qhov kev pab cuam CMM txij thaum pib mus txog rau thaum xaus.
Kev ua haujlwm tiag tiag hauv ntiaj teb hinges ntawm peb qhov tsis sib tham - tsis yog kev lag luam thov. Ua ntej: cov khoom sib xws. Txhua Stellite 6 ntau dhau kev soj ntsuam spectrographic, hardness mapping hla hla ntu, thiab ASTM E112 grain loj pov thawj. Thib ob: qhov fidelity. Peb siv tau qhov chaw tseem ceeb uas siv optical profilometers - tsis yog CMMs xwb - txhawm rau ntes micro-topography uas cuam tshuam rau kev sib khi. Thib peb: ua haujlwm validation. Ua ntej xa khoom, txhua lub siab valve tau kuaj xyuas hydrostatic ntawm 1.5 × ntsuas kev ua haujlwm siab; Txhua lub twj tso kua mis vaj tsev tau txais kev xau-kuaj nrog helium huab hwm coj spectrometry. Cov neeg siv khoom hauv North America thiab Europe tsis thov daim ntawv pov thawj-lawv nug cov ntawv xeem tshwj xeeb nrog cov ntawv teev sijhawm, tus neeg teb xov tooj ID, thiab cov khoom siv ntsuas ntsuas. Peb xa lawv.
Yog tias koj daim ntawv thov cuam tshuam nrog cov slurries abrasive, kub-kub, los yog cyclic loading saum 200 MPa, Stellite 6 tsis dhau-engineering. Nws yog insurance. Tab sis kev pov hwm tsuas yog ua haujlwm thaum tus kws kho mob tau txais kev paub dhau los - tsis yog daim ntawv qhia xwb. Saib rau cov ntaub ntawv ua tiav hauv koj txoj haujlwm: twj tso kua mis sib dhos rau subsea daim ntaub ntawv, winch center ncej chais rau heavy-duty cranes, los yog cobalt alloy nozzles rau desalination nroj tsuag. Xyuas seb lawv tuav AMS 5387 cov txheej txheem kev pom zoo - tsis yog cov ntaub ntawv pov thawj nkaus xwb. Tshawb xyuas seb lawv cov ntaub ntawv zoo li cas suav nrog tag nrho traceability mus rau tus xov tooj cua sov ntawm cobalt ingot. Tom qab ntawd sib piv kev qhuab qhia kev xa khoom: lawv puas tuaj yeem tuav ± 3-hnub qhov rais ntawm qhov nruab nrab-ntim xaj yam tsis tau them nqi nrawm? Qhov ntawd yog qhov kos npe ntawm qhov tseeb Stellite 6 qhov chaw Hoobkas- tsis yog lub khw muag khoom nrog cov ntaub ntawv cobalt alloy.
