Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm lub ntiaj teb no tsheb, hluav taws xob hluav taws xob, thiab high -kawg manufacturing industries, qhov kev thov rau siab - kev ntseeg siab ntawm hluav taws xob tiv tauj cov ntaub ntawv tau nce mus ntxiv. Ntawm lawv, Tungsten Contacts, nrog lawv cov arc zoo heev, tsis tshua muaj vapor siab, siab melting point, thiab thermal stability, tau dhau los ua cov khoom tseem ceeb hauv ntau lub tshuab hluav taws xob tseem ceeb. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, Tungsten Contact Rivets cov ntaub ntawv feem ntau ntsib cov teeb meem xws li phab ntsa tawg, tawg tawg, ntxhib lossis tsis sib xws hauv cov pob txha tawg, thiab kev sib txawv ntawm cov pas nrig txoj kab uas hla, uas cuam tshuam rau cov khoom lag luam thiab kev ua haujlwm zoo. Txhawm rau daws cov teeb meem no, qee cov tuam txhab tsim khoom hauv tsev tau txhim kho cov khoom lag luam zoo ruaj khov los ntawm kev ua kom zoo dua qub.
Txawm li cas los xij, nyob rau hauv cov txheej txheem tsim khoom tiag tiag ntawm Tungsten Steel Sib cuag cov ntaub ntawv, vim yog cov khoom siv nyuaj thiab kev ua haujlwm siab, cov teeb meem xws li phab ntsa tawg, tawg tawg, tsis sib xws ntawm cov nplej faib rau ntawm tus ntoo khaub lig- ntu, thiab qhov nyuaj ntawm kev tswj cov pas nrig qhov ntev feem ntau tshwm sim. Cov teeb meem no tsis yog tsuas yog cuam tshuam rau cov khoom siv kho tshuab, tab sis kuj ncaj qha txo cov conductivity stability thiab kev pab cuam lub neej ntawm cov neeg nyob rau hauv lub sij hawm ua hauj lwm. Yog li ntawd, kev tshuaj xyuas cov ntsiab lus tseem ceeb cuam tshuam rau qhov zoo thiab kev ua kom zoo ntawm cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev txhim kho cov txiaj ntsig thiab kev ntseeg siab ntawm Tungsten Point Contact cov ntaub ntawv.
Los ntawm qhov kev xav ntawm cov khoom siv, Tsheb Horn Tungsten Hu rau Rivets cov ntaub ntawv muaj cov khoom zoo heev. Ua ntej, tungsten muaj qhov taw tes melting siab heev, ua rau nws tswj tau cov qauv ruaj khov nyob rau hauv siab -kub arc tej yam kev mob. Qhov thib ob, cov khoom siv tsis tshua muaj coefficient ntawm thermal expansion, ua rau nws tsis tshua muaj kev cuam tshuam rau cov txheej txheem deformation thaum nquag hloov mus rau thiab tawm ntawm lub zog. Tsis tas li ntawd, tungsten muaj qhov tsis tshua muaj vapor siab thiab qeeb volatilization tus nqi ntawm qhov kub thiab txias, yog li nthuav tawm qhov ua haujlwm zoo rau ablation nyob rau hauv arc tej yam kev mob.
Txawm hais tias muaj cov khoom zoo ntawm cov khoom siv tungsten, lawv cov khoom tsim tawm tseem ntsib ntau yam kev sib tw. Ib qho teeb meem feem ntau yog cov teeb meem metallurgical nyob rau hauv lub billet. Thaum lub sij hawm tungsten smelting, tsis txaus raw khoom purity los yog cov txheej txheem tsis tsim nyog yuav ua tau yooj yim ua rau cov tsim ntawm pores, inclusions, los yog impurities nyob rau hauv lub billet. Cov kev tsis zoo no ua rau lub zog sib txuas ntawm cov nplej hlau, ua rau tawg lossis tawg thaum lub sijhawm ua cov yas tom ntej. Piv txwv li, qee yam qis- melting- taw tes impurities, xws li txhuas thiab bismuth, feem ntau nyob ntawm cov ciam teb, yooj yim los ua qhov pib rau kev tawg tawm thaum lub sij hawm ua, ua rau tawg lossis tawg tawg.
Qhov thib ob, kev tswj cov hmoov av me me thiab kev faib ua feem yog qhov tseem ceeb hauv cov hmoov metallurgy theem. Tsis sib luag particle loj tis los yog tsis txaus sib tov yuav yooj yim ua rau cov tsim ntawm cov siv lead ua sib txawv thaum lub sij hawm sintering, xws li ib tug sib tov ntawm nplua, ntxhib, thiab ncej-zoo li nplej. Qhov kev sib txawv ntawm cov qauv no cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov khoom, ua rau cov yas deformation tsis zoo nyob rau hauv qee qhov chaw, ua rau muaj kev sib tsoo hauv cheeb tsam thaum lub sij hawm teb forging los yog ncab. Yog li ntawd, kev tswj xyuas nruj ntawm cov hmoov particle loj tis thiab ua kom muaj kev sib xyaw ua ke yog qhov tseem ceeb thaum lub sij hawm npaj cov Pure Tungsten Discs.
Tsis tas li ntawd, kev tswj cov txheej txheem thaum lub sij hawm billet nias thiab sintering kuj cuam tshuam cov khoom zoo. Tsis sib npaug nias lub siab faib ua rau inconsistent internal ntom nyob rau hauv lub billet, uas ua rau ib tug uneven qauv. Thaum lub sij hawm tom qab sintering, cov cheeb tsam sib txawv me me ntawm qhov sib txawv, ua rau delamination lossis tawg. Tib lub sijhawm, kev tswj qhov kub tsis ruaj khov lossis lub sijhawm tuav tsis txaus tuaj yeem ua rau qis dua - lossis dhau - hlawv, ua rau muaj kev hloov pauv hauv cov qauv nplej thiab cuam tshuam rau kev ua haujlwm tom ntej.
Hauv kev ua cov hmoov Petallurgy tungsten Discs, rotary forging yog ib kauj ruam tseem ceeb hauv kev tsim cov khoom kawg. Rotary forging zoo refines lub grain qauv thiab ua rau kom cov ntaub ntawv ceev. Nyob rau hauv thawj theem ntawm kev ua, ib tug ntau dua pass tus nqi yuav siv tau los ua kom ntau lawm efficiency, cia lub billet kom sai li sai tau raws li lub hom phiaj loj. Txawm li cas los xij, nyob ze rau theem khoom tiav, tus nqi dhau yuav tsum tau tswj nruj me ntsis kom tsis txhob muaj qhov deformation ntau dhau uas tuaj yeem ua rau cov kab nrib pleb. Feem ntau, tus nqi dhau ntawm ib lossis ob txheej txheem ua ntej cov khoom tiav yuav tsum tau tswj ntawm 12% thiab 15%, thaum kawg cov khoom lag luam yuav tsum tau txo qis ntxiv rau ntawm 5% thiab 9%.
Nyob rau hauv cov khoom siv hluav taws xob niaj hnub no, Tungsten Contact Rivets tsis yog siv hauv kev tswj kev lag luam nkaus xwb tab sis kuj tau siv dav hauv tsheb hluav taws xob, khoom siv sib txuas lus, thiab cov tshuab hluav taws xob tshiab. Cov khoom xws li Horn Contact Wolfram thiab Motorcycle Horn Tungsten Rivet ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm lub tsheb horns. Tsis tas li ntawd, nrog kev nce ntxiv ntawm cov khoom siv hluav taws xob siab, qhov kev thov siab rau -arc- cov ntaub ntawv tiv tauj tau loj hlob tas li, muab cov khoom xws li Tungsten Discs muaj kev cia siab rau kev lag luam.
Zuag qhia tag nrho, kev tsim cov Motorcycle Horn Tungsten Rivet cov ntaub ntawv yog ib txoj haujlwm engineering uas muaj ntau yam kev qhuab qhia xws li hmoov metallurgy, kev ua cov yas, thiab kev tsim khoom. Tsuas yog los ntawm kev tswj hwm nruj ntawm ntau theem, suav nrog kev xaiv cov khoom siv raw, cov txheej txheem sintering, rotary forging, thiab pwm tsim, tuaj yeem ua kom cov khoom ruaj khov thiab txhim khu kev qha txhua yam muaj zog. Nrog rau kev nce qib hauv kev tsim cov thev naus laus zis thiab kev nthuav dav ntxiv ntawm thaj chaw thov, qhov tseem ceeb ntawm Copper Tungsten Sib cuag cov ntaub ntawv hauv kev lag luam hluav taws xob yuav nce ntxiv.
