Thaum cov khoom siv mining ua tsis tau raws li kev thauj khoom, lub sijhawm poob qis tsis ntsuas hauv cov xuab moos - nws suav nrog cov tons ploj, kev xa khoom qeeb, thiab cov nqi kho mob cascading. Cov neeg ua haujlwm tsis xav tau ntau qhov chaw. Lawv xav tau qhov raug: dimensionally ruaj khov, metallurgically zoo ib yam, thiab muaj pov thawj nyob rau hauv 300-bar hydraulic circuits los yog abrasive ore- tuav winch systems. Tias yog vim li cas thoob ntiaj teb OEMs thiab Tier-1 cov chaw muag khoom tau nce mus rau ib qho mining khoom qhov chaw Hoobkas uas kho cov khoom siv science li engineering-tsis yog kev yuav khoom.
Vim li cas "Ua Hauv Tuam Tshoj" Tsis Muaj Ntev Lawm txhais tau tias "kev sib haum xeeb ntawm kev thuam"
Peb tau pom nws ua ntej: tus neeg teb xov tooj North American chaw txua txiag zeb tau hloov peb qhov txuas ntxiv ntawm cobalt-alloy twj nozzles los ntawm cov neeg muag khoom. Txhua qhov ua tsis tau tiav ua ntej 400 lub sijhawm ua haujlwm-micro-cracking ntawm lub caj pas lub vojvoog, qhov tsis sib xws AMS 5387 grain qauv, qhov dav dav tom qab kev kho cua sov. Plaub pawg tuaj ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Nws khiav 2,170 teev - tsis muaj kev rov ua haujlwm dua, tsis muaj kev hloov pauv hauv thaj chaw. Qhov txawv tsis yog machining precision xwb. Nws yog ntsug kev koom ua ke: kev tswj casting, alloy-tshwj xeeb kev kho cua sov raws tu qauv, thiab CMM validation ntawm txhua theem - tsis yog tsuas yog zaum kawg kev soj ntsuam.
Qhov no tsis yog theoretical. Lawv qhov chaw ISO-raws li hauv Qingdao tuav tag nrho cov saw: peev casting rau nyias-walled siab valve lub cev, multi-axis CNC contouring ntawm piston twj tso kua mis lub tog raj kheej vaj tse (± 0.015 hli GD&T kam rau ua), thiab tom qab machining nto kev ntseeg siab siv optical profilometry. Thaum lub European engineering tsheb OEM xav tau winch center ncej chais nrog hardened rooj tob ≥1.2 hli thiab core hardness 32–36 HRC, lawv tsis outsource casting thiab machining nyias. Lawv xa ib daim duab-thiab tau txais ib daim ntawv pov thawj ntau, traceable rau raw cov ntaub ntawv heats, nrog tag nrho MTRs thiab microstructure qhia.
Tsis muaj kev sib haum xeeb Alloy tuav—Qhov twg feem ntau Factories nres, Lawv pib
Qee cov factories tshuab stainless hlau. QINGDAO QIANGSENYUAN cov cav tov T800 cobalt-based superalloys-cov khoom uas ua hauj lwm-harden sai tshaj li cov cuab yeej yuav txiav, thov sub-0.5 ° C thermal stability thaum tov annealing, thiab tsis lees paub cov txheej txheem quenching media. Lawv AMS 5387 cobalt alloy 6 lub twj tso kua mis tsis yog "tsuas yog nrum." Lawv raug muab pov rau hauv lub tshuab nqus tsev vacuum-inert cua rauv, kev daws teeb meem ntawm AMS 2750E, tom qab ntawd muaj hnub nyoog nrog lub sijhawm tiag tiag thermocouple daim ntawv qhia hla txhua ntu ntu ntu.
Qhov peev xwm no cais lawv los ntawm cov khw muag khoom hlau dav dav. Cobalt-nickel alloys tsis yog hais txog hardness ib leeg-lawv yuav tsum tau tswj delta-theem nag lossis daus los tiv thaiv galling hauv high-plam interfaces. Lub voj voog kev laus tsis raws sij hawm hloov lub twj tso kua mis rau hauv qhov kev pheej hmoo qaug dab peg. Peb tau tshuaj xyuas lawv cov ntaub ntawv tsim tawm: txhua T800 ntau suav nrog SEM-EDS kev soj ntsuam pom zoo rau theem kev faib tawm, tsis yog cov tshuaj lom neeg ntau. Qhov ntawd yog hom kev mining nruj OEMs tam sim no xav tau - tsis yog rau kev ua raws, tab sis rau kev kwv yees.
Tsim-rau-kev qhuab qhia-tsis muaj kev xav tsis thoob, tsis muaj kev rov ua dua
"Koj puas tuaj yeem ua qhov no?" yog thawj lo lus nug tsis raug. Qhov zoo yog: "Qhov no yuav ua li cas * ua * hauv koj lub cev - thiab dab tsi yuav tawg ua ntej yog tias peb ua kom zoo rau tus nqi xwb?" QINGDAO QIANGSENYUAN pab pawg engineering tsis tos POs. Lawv koom nrog thaum tsim kev tshuaj xyuas-flagging lub kaum sab xis tob dhau rau cov xuab zeb casting, tawm tswv yim fillet radii uas tiv thaiv kev ntxhov siab nyob rau hauv high-cycle winch shafts, validating GD&T callouts tiv thaiv kev ua hauj lwm txwv.
- Lawv ntes cov teeb meem cuam tshuam ua ntej cov cuab yeej pib - txiav lub sij hawm prototyping los ntawm 30% ntawm qhov nruab nrab
- Lawv cov txheej txheem casting-machining hybrid tshem tawm cov teeb meem thib ob hauv cov twj tso kua mis complex
- Txhua qhov khoom xa tuaj suav nrog cov ntawv qhia qhov ntev raws li ASME Y14.5, tsis yog cov ntawv hla / tsis ua haujlwm xwb
Qhov no tsis yog kev ua yeeb yam. Nws tau sau ua haujlwm ua haujlwm: kos duab tso tawm → cov ntaub ntawv pov thawj sib tw → thawj tsab ntawv CMM daim ntawv tshaj tawm → hauv cov txheej txheem tuab pov thawj → kev sim ua haujlwm zaum kawg (xws li kev ntsuas siab ntawm 1.5 × ua haujlwm siab). Tsis muaj ib yam dab tsi uas tsis muaj traceability tag nrho - cov xov tooj cua sov, tus neeg teb xov tooj ID, tshuab ID, tshuaj xyuas lub sij hawm.
Kev ntseeg tsis yog qhov tshwj xeeb. Nws yog Qhov Tshaj Tawm ntawm Txhua Qhov Kev Txiav Txim Siab.
Ib tug txhim khu kev qha mining khoom qhov chaw Hoobkas tsis cog lus tias xoom tsis xws luag. Nws lav qhov kev daws teeb meem hauv paus-hauv 72 teev-rau txhua qhov tsis sib xws. Nws tuav ob qhov kev pom zoo nrog cobalt alloy cov chaw muag khoom yog li ib lub zeb tawg tsis ncua koj qhov kev txiav txim. Nws tuav cov khoom ntawm lub siab valve blanks hauv AMS 5387 thiab ASTM A48 Class 35 hlau-txo lub sij hawm txhuas los ntawm 14 lub lis piam mus rau 3.
Saib ua ntej, lawv qhov R & D tsom tsis yog qhov ntsuas qhov ntim. Nws yog nyob rau ntawm cov txheej txheem hybrid: ze-net-puab peev castings nrog kev sib xyaw ua ke cua txias rau kev tswj xyuas thermal nyob rau hauv high-duty-cycle twj, thiab laser-pab machining ntawm cobalt alloys uas txiav cov cuab yeej hnav los ntawm 60%. Cov no tsis yog lab xav paub. Lawv tau xa mus rau cov neeg Esxias sab hnub tuaj Asia tooj liab concentrators thiab Norwegian offshore roj & roj skids - ib puag ncig uas tsis ua hauj lwm tsis yog ib qho kev xaiv.
Yog tias koj qhov kev txiav txim siab tom ntej no cuam tshuam txog qhov rov ua tau zoo dua qub, kev ntseeg siab ntawm alloy, lossis kev xa khoom raws sijhawm ntawm lub luag haujlwm tseem ceeb - pib nrog kev tshuaj xyuas, tsis yog daim ntawv nqi. Tus nqi kim tshaj plaws tsis yog tus nqi siab tshaj plaws. Nws yog ib qho uas tsis ua haujlwm nruab nrab, faus hauv qab 200 tons ntawm ore.
