Hauv lub kaw lus nyuaj ntawm kev lag luam niaj hnub no, ntau cov txheej txheem tseem ceeb ntawm kev tsim khoom vam khom cov ntaub ntawv thiab cov khoom uas zoo li tsis tseem ceeb tab sis qhov tseeb tseem ceeb. Silicon carbide rollers yog ib qho ntawm lawv. Txawm hais tias qis qis, nws ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw ua haujlwm kub siab thiab tuaj yeem suav tias yog tus phab ej tom qab qhov xwm txheej ntawm kev lag luam kub siab.
Silicon carbide rollers, raws li nws lub npe qhia, nws cov khoom tseem ceeb yog silicon carbide (SiC). Silicon carbide yog ib qho khoom sib xyaw ua ke uas sib xyaw cov yam ntxwv ntawm carbon thiab silicon los tsim cov khoom zoo heev. Cov khoom siv no muaj qhov nyuaj siab, thib ob tsuas yog pob zeb diamond, thiab muaj kev tiv thaiv zoo hnav, ib yam li ib tug tub rog hnav khaub ncaws ua rog, nws tuaj yeem tswj nws txoj kev ncaj ncees txawm tias nyob rau hauv qhov chaw ua haujlwm hnyav. Tib lub sijhawm, nws kuj muaj kev tiv thaiv kub zoo heev thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub siab yam tsis yooj yim deforming lossis ua puas tsuaj. Qhov no ua rau silicon carbide rollers sawv tawm hauv kev lag luam kub siab thiab dhau los ua cov khoom siv nyiam rau ntau lub tuam txhab.
Hauv kev lag luam ceramic, qhov muaj cov silicon carbide rollers tuaj yeem pom txhua qhov chaw. Hauv cov txheej txheem tua hluav taws ntawm ceramics, nws yog qhov tsim nyog los sinter lub cev ceramic hauv lub qhov cub kub siab kom nws ntom thiab tau txais cov khoom xav tau. Lub silicon carbide roller ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa thiab kev xa khoom thaum lub sijhawm no. Nws tuaj yeem tiv taus qhov siab loj heev hauv qhov chaw kub siab, ua kom muaj kev txav mus los du thiab cua sov sib xws ntawm cov khoom ceramic hauv qhov cub, yog li ua kom ntseeg tau tias qhov zoo thiab sib xws ntawm cov khoom ceramic. Piv rau cov ntaub ntawv roller ib txwm muaj, silicon carbide rollers muaj lub neej ua haujlwm ntev dua, uas tuaj yeem txo qhov zaus ntawm kev hloov roller, txo cov nqi tsim khoom, thiab txhim kho kev ua haujlwm ntau lawm.
Hauv kev lag luam tsim iav, cov menyuam silicon carbide kuj ua lub luag haujlwm tseem ceeb. Hauv cov txheej txheem ntawm kev tsim thiab ua cov iav, nws yog qhov tsim nyog los ncab thiab nias cov kua iav ntawm qhov kub siab kom tsim ntau yam duab ntawm cov khoom iav. Cov menyuam silicon carbide tuaj yeem sib cuag nrog cov iav molten ntawm qhov kub siab yam tsis muaj kev tshuaj lom neeg, ua kom ntseeg tau tias qhov huv thiab zoo ntawm cov iav. Tib lub sijhawm, nws qhov kev tiv thaiv kev hnav siab kuj tso cai rau cov menyuam bar kom tswj tau qhov zoo ntawm qhov chaw du tom qab siv ntev, ua kom ntseeg tau tias qhov zoo ntawm cov khoom iav.
Ntxiv rau kev lag luam ceramic thiab iav, silicon carbide rollers kuj tseem siv dav hauv cov teb xws li semiconductors, hlau ua, thiab hmoov metallurgy. Hauv kev tsim khoom semiconductor, nws yog siv rau kev txhuam thiab hloov silicon wafers, kom ntseeg tau tias muaj kev tsim khoom siab ntawm cov khoom siv semiconductor; Hauv kev ua hlau, nws yog siv rau kev dov kub siab thiab kev kho cua sov, uas txhim kho kev ua tau zoo thiab zoo ntawm cov khoom siv hlau; Hauv hmoov metallurgy, nws yog siv rau kev nias hmoov thiab sintering, txhawb kev ua kom cov khoom siv ntom ntom thiab kev ua tau zoo.
Nrog rau kev nce qib ntawm thev naus laus zis thiab kev txhim kho sai ntawm kev lag luam, qhov kev xav tau ntawm kev ua tau zoo rau cov menyuam silicon carbide kuj nce ntxiv. Txhawm rau kom tau raws li cov kev xav tau no, cov kws tshawb fawb thiab cov tuam txhab lag luam pheej nqis peev rau kev tsim kho tshiab thiab kev tshawb fawb thiab kev txhim kho. Los ntawm kev txhim kho cov txheej txheem tsim khoom thiab cov mis, kev ua tau zoo thiab zoo ntawm cov menyuam silicon carbide tau txhim kho, ua rau lawv tiv taus qhov kub siab, hnav, xeb, thiab muaj peev xwm hloov kho rau cov chaw ua haujlwm nyuaj thiab xav tau ntau dua.
Cov menyuam roj hmab silicon carbide, ua cov khoom siv tseem ceeb hauv kev lag luam kub siab, txawm hais tias zoo li qub, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nws qhov kev ua tau zoo heev thiab kev siv dav dav muab kev txhawb nqa zoo rau kev txhim kho kev lag luam niaj hnub. Yav tom ntej, nrog rau kev tsim kho tshiab ntawm thev naus laus zis thiab kev nthuav dav ntawm cov teb thov, peb ntseeg tias cov menyuam roj hmab silicon carbide yuav txuas ntxiv tso tawm lub teeb thiab cua sov hauv kev lag luam kub siab, tsim kom muaj txiaj ntsig ntau dua.
