Tshooj 1: Cov khoom siv carbide yog dab tsi?
Cemented carbide yog ua los ntawm tungsten carbide thiab cobalt.Tungsten carbide yog cov khoom siv nrog lub siab melting point.Nws yuav tsum tau muab tso rau hauv cov hmoov thiab tom qab ntawd tsim los ntawm high-temperature combustion thiab solidification, thiab cobalt ntxiv raws li ib tug binding khoom.Tungsten feem ntau yog los ntawm Tuam Tshoj, Russia thiab Kaus Lim Qab Teb, thaum cobalt los ntawm Finland, Canada, Australia thiab Congo.Yog li ntawd, ua superhard alloys yuav tsum muaj kev koom tes thoob ntiaj teb los siv cov khoom xav tsis thoob no rau ntau qhov chaw sib txawv. Feem ntau siv cov cemented carbides tau muab faib ua peb pawg raws li lawv qhov muaj pes tsawg leeg thiab kev ua tau zoo: tungsten-cobalt, tungsten-titanium-cobalt, thiab tungsten- titanium-cobalt (niobium).Feem ntau siv hauv kev tsim khoom yog tungsten-cobalt thiab tungsten-titanium-cobalt cemented carbide.
Txhawm rau ua kom muaj zog super alloy, nws yog ib qho tsim nyog yuav tsum tau grind tungsten carbide thiab cobalt rau hauv cov hmoov zoo, thiab hlawv thiab khov ntawm qhov kub siab (1300 ° C txog 1500 ° C) kom khov cov khoom.Cobalt tau ntxiv los ua cov khoom sib txuas los pab cov tungsten carbide hais lo rau ib leeg.Qhov tshwm sim yog cov hlau uas muaj zog heev nrog lub melting point ntawm 2900 ° C, ua rau nws resistant rau kub thiab zoo haum rau high-temperature daim ntaub ntawv.
Tshooj 2: Kev siv cov khoom siv carbide yog dab tsi?
Cemented carbide muaj ntau yam kev siv.Hauv kev lag luam kev lag luam, nws tau siv dav hauv kev tsim cov cuab yeej txiav rau kev ua hlau xws li CNC drilling cuab yeej, CNC milling tshuab, thiab CNC lathes.Tsis tas li ntawd, nws tuaj yeem siv los ua pwm rau txhuas cov kaus poom xws li kas fes thiab dej haus, hmoov molding pwm rau automotive engine qhov chaw (sintered qhov chaw), thiab pwm rau cov khoom siv hluav taws xob xws li xov tooj ntawm tes.
Nyob rau hauv cov nqe lus ntawm ntau lawm thiab ua, qhov tseem ceeb ntawm super hard alloy yog nws tus kheej-pov thawj.Vim nws zoo heev hardness thiab lub zog, superhard alloys yog dav siv nyob rau hauv machining cov cuab yeej xws li hlau txiav, drilling cuab yeej, milling tshuab thiab lathes.Tsis tas li ntawd, nws tuaj yeem siv los ua cov txhuas tuaj yeem pwm rau cov kaus poom kas fes thiab dej haus, hmoov molding pwm rau automotive engine qhov chaw (sintered qhov chaw), thiab pwm rau cov khoom siv hluav taws xob xws li xov tooj ntawm tes, thiab lwm yam.
Txawm li cas los xij, superhard alloys tsis txwv rau kev ua cov hlau ua thiab kev tsim khoom.Nws kuj tseem tuaj yeem siv rau kev sib tsoo ntawm cov pob zeb nyuaj, xws li kev tsim kho ntawm cov ntaub thaiv npog, thiab txiav txoj kev asphalt thiab lwm cov teb.Tsis tas li ntawd, vim nws cov yam ntxwv zoo heev, superhard alloys kuj tuaj yeem siv dav hauv lwm cov teb rau CNC machining.Piv txwv li, cov cuab yeej phais siv nyob rau hauv kev kho mob, cov mos txwv thiab warheads nyob rau hauv cov tub rog teb, engine Cheebtsam thiab aircraft turbine hniav nyob rau hauv lub aerospace teb, thiab lwm yam.
Ntxiv rau daim ntawv thov hauv kev lag luam, super hard alloys kuj ua lub luag haujlwm hauv kev tshawb fawb txog kev tshawb fawb.Piv txwv li, nws tuaj yeem siv los ua cov diffraction rods hauv X-ray thiab kev tshawb fawb kho qhov muag, thiab ua ib qho catalyst hauv kev kawm txog tshuaj tiv thaiv.
Tshooj 3: Dab tsi yog qhov nyuaj ntawm carbide ib feem machining?
Kev ua cov cemented carbide tsis yooj yim thiab muaj ntau yam teeb meem.Ua ntej ntawm tag nrho cov, vim nws siab hardness thiab brittleness, ib txwm ua txoj kev yog feem ntau nyuaj rau ua tau raws li qhov yuav tsum tau thiab yuav yooj yim ua rau tsis xws luag xws li tawg thiab deformation nyob rau hauv cov khoom.Thib ob, cemented carbide yog siv nyob rau hauv high-end teb, yog li qhov yuav tsum tau rau machining raug yog siab heev.Thaum lub sij hawm ua cov txheej txheem, ntau yam yuav tsum tau muab rau hauv kev txiav txim siab, xws li cov cuab yeej txiav, fixtures, txheej txheem tsis, thiab lwm yam, los xyuas kom meej cov khoom raug.Thaum kawg, qhov zoo ntawm qhov yuav tsum tau muaj ntawm cemented carbide kuj siab heev.Vim nws qhov brittleness ntau dua, qhov saum npoo tau yooj yim puas, yog li kev ua haujlwm tshwj xeeb thiab cov khoom siv (xws li ultra-precision grinders, electrolytic polishers, thiab lwm yam) yuav tsum tau siv los xyuas kom meej qhov zoo.
Hauv luv luv, cemented carbide tau nce siv hauv CNC machining, ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev tsim khoom thiab cov khoom zoo hauv tshuab, hluav taws xob, tshuaj, aerospace thiab lwm yam lag luam.GPM muaj cov cuab yeej ua haujlwm siab heev thiab thev naus laus zis uas tuaj yeem ua cov khoom supercarbide tau zoo thiab raug. .Kev tswj hwm nruj nruj thaum lub sijhawm ua cov txheej txheem ua kom txhua qhov ua tau raws li cov neeg siv khoom xav tau thiab cov qauv.
