Nyob rau hauv siab - siv mining, tunneling, thiab infrastructure tej yaam num, sab saum toj rauj drilling cov cuab yeej yuav tsum tau nyiaj dhau heev heev frequencies thiab loj rotational torque. Nyob rau hauv cov xwm txheej phem no, txhua qhov kev cuam tshuam hauv kev tsim khoom tuaj yeem ua rau muaj kev puas tsuaj loj rau kev ua haujlwm tsis zoo, nres kev ua haujlwm thiab kev ua haujlwm ntau tus nqi. Txhawm rau tiv thaiv qhov no, cov khoom siv xov tooj zoo tshaj plaws -xws li T38 laum pas nrig, T45 laum pas nrig, thiab T51 laum pas nrig- yuav tsum ua raws li cov txheej txheem zoo ua ntej ntim thiab xa khoom: Cov khoom siv raw khoom Incoming Inspection → Semi{{8}{9} Kev Tswj Xyuas Zoo Tshaj Plaws Kev Xeem → 100% Cov Khoom Ua tiav Kev Tshawb Fawb Kawg. Cov txheej txheem no ua kom ntseeg tau tias txhua lub cuab yeej ua tiav plaub lub ntsiab lus ntawm cov qauv kev tsim vaj tsev: tsis yog - kuaj kev puas tsuaj rau cov pas nrig, cov xov tsis zoo, qhov ua kom zoo tshaj plaws laum pas nrig hardness HRC, thiab cov dej muaj zog - qhov sib khi ruaj khov.
Theem 1: Raw Material Incoming Inspection (Hollow Steel Billet Phase)
Qhov kev ua tau zoo ntawm - zoo laum pas nrig pib nrog kev tshuaj xyuas cov khoom siv raw.Advanced spectrometric tsom xamtxheeb xyuas cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov qib zoo hollow steel xws li 23CrNi3Mo thiab 55SiMnMo, kom ntseeg tau tias qib siab ntawm Cr, Ni, Mo, Mn, thiab Si thaum tshem tawm cov khoom siv tsis zoo.Tag nrho -ntev ultrasonic kuaj (UT)Ntxiv mus nrhiav tau cov laminations sab hauv, shrinkage kab noj hniav, slag inclusions, thiab micro-kawg, kom ntseeg tau tias tsuas yog tsis xws luag- dawb billets mus rau ntau lawm. Txhawm rau lav qhov tseeb qhov tseeb thiab kev ua haujlwm machining, txhua daim ntawv hlais tau ua tiavDimension thiab straightness soj ntsuam, npog sab nraud, sab hauv lub qhov dej ntws tawm, hexagonal qhov ntev, thiab pas nrig ncaj. Ntxiv rau,metallographic micro-samplingntsuam xyuas cov qauv nplej thiab annealing hardness, muab cov khoom zoo tagnrho rau cov xov machining meej thiab lub neej ua haujlwm ntev.
Kauj Ruam 2: Hauv - Txheej Txheem Ib Nrab - Kev Tshawb Fawb Ua tiav (Post-Kev ntxhov siab & xov)
Thaum lub sij hawm machining thiab forging, intermediate zoo tswj xyuas kom txhua tus laum pas nrig ua tau raws li nruj kev tsim qauv ua ntej kev kho cua sov.Forged xub pwgraug tshuaj xyuas pom thiab txheeb xyuas los ntawmMagnetic particle kuaj (MPI)txhawm rau txheeb xyuas qhov tsis xws luag los ntawm kub deformation, thaum100% xov tshuaj xyuassiv precision gauges lees paub xov profile, suab, thiab qhov tseeb qhov tseeb rau kev sib txuas txhim khu kev qha. Yuav kom ua tau zoo drilling kev ua tau zoo, txhua tus pas nrig kuj undergoes akev tshuaj xyuas qhov dej ntws tawm, xyuas kom meej tias cov dej hauv dej hauv dej tsis pub dawb los ntawm cov nplai, slag, lossis forging ob qho tib si, tso cai rau tsis muaj kev cuam tshuam thaum lub sijhawm ua haujlwm.
Theem 3: Kev Tshaj Tawm Tshwj Xeeb- Kev Ntsuas Kev Kho Hniav Kub (Lub Sij Hawm Ntev Ntev)
Kev kho cua sov yog qhov tseem ceeb rau kev hnav tsis kam thiab qaug zog lub neej ntawm laum rods. Tom qab quenching thiab carburizing, txhua tus pas nrig undergoes100% hardness xyuas, xyuas kom cov xov ua tiav HRC 58-62 rau qhov siab tshaj plaws hnav tsis kam, thaum lub cev pas nrig tuav ntawm HRC 38-42 los muab cov tawv tawv uas yuav tsum tau nqus rov qab cuam tshuam.Carburized roojQhov tob kuj tau ntsuas los txheeb xyuas cov txheej txheem 0.8-1.2 mm hardened rau kev pom xov ntev. Txhawm rau kom ntseeg tau qhov tseeb ntawm cov qauv thiab ntev - lub sijhawm kev ntseeg siab, txhua tus pas nrig raug kuaj xyuaskev ncajthiab hydraulically kho nyob rau hauv tsawg dua los yog sib npaug rau 0.3 mm / m yog tias xav tau. Kev ua tau zoo ntawmtua peeningNws tseem raug txheeb xyuas kom ntseeg tau tias cov txheej txheem kev ntxhov siab tsis sib xws, txhim kho kev qaug zog thiab ua rau lub neej ntev.
Kauj Ruam 4: 100% Cov Khoom Muag Kawg Ua tiav Kev Tshawb Fawb
Ua ntej ua zaub mov xa tuaj, txhua qhov kev xyaum ua tiav tiav undergoes100% kev soj ntsuam zaum kawglos xyuas kom meej qhov zoo thiab kev ntseeg siab.Magnetic particle xeem (MT)yog ua rau ntawm qhov chaw muaj kev ntxhov siab tseem ceeb txhawm rau txheeb xyuas qhov micro- tawg, thaumxov haum thiab sib dhos xeemtxheeb xyuas kev sib koom ua ke thiab kev sib raug zoo nrog tus tswv couplings thiab shank adapters. Siab -siablub qhov dej ntwssealing kev ntsuam xyuas ntxiv kom paub tseeb tias xau- cov kua dej dawb kom ua kom txias tau zoo thiab tshem tawm cov txiav. Txhua feem kuj tau txais kev qhiakev tshuaj xyuas qhov muag thiab qhov ntev, kuaj xyuas qhov chaw, tiv thaiv- txheej txheej corrosion, laser marking, tag nrho ntev, hexagonal profile, thiab lwm yam tseem ceeb qhov ntev kom ntseeg tau tias ua raws li cov qauv tsim ua ntej xa khoom.
Los ntawm kev ua tiav qhov nruj, ntau- txheej txheej tswj kev tswj hwm zoo, Gdrills ua kom ntseeg tau tias txhua T38, T45, thiab T51 laum pas nrig xa mus rau lub tshav pob muab kev sib tw laum rods zoo, tsav kev ua haujlwm tau zoo.
