Kev tsim khoom tas mus li yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm zoo hauv cov qhov cub kub siab hauv kev lag luam xws li cov khoom siv av nplaum thiab iav. Cov khoom ua haujlwm yuav tsum txav mus los zoo thiab raug cua sov sib npaug ntawm qhov kub siab, thiab lub hauv paus tseem ceeb uas ua tiav txhua yam no yog tus pas nrig zoo li qub tab sis tseem ceeb. Hnub no peb yuav tham txog "lub luag haujlwm ruaj khov" hauv cov pas nrig -silicon carbide rollers.
Qhov chaw ua haujlwm ntawm lub roller bar yog qhov hnyav heev: nws yuav tsum tig tas li ntawm qhov kub thiab txias heev, tiv taus qhov hnyav, xeb, thiab hnav ntawm qhov workpiece, thiab tseem ntsib kev hloov pauv kub hnyav thaum pib thiab kaw. Cov ntaub ntawv ib txwm muaj feem yuav deformation, tawg, lossis xeb, ua rau muaj kev kaw thiab hloov pauv ntau zaus, cuam tshuam rau kev tsim khoom thiab nce nqi.
Cov khoom siv silicon carbide tuaj yeem ua tau raws li cov teeb meem no: nws tiv taus qhov kub thiab txias siab, thermal shock, hardness siab, hnav thiab corrosion, thiab tuaj yeem ua haujlwm ruaj khov hauv qhov chaw kub heev rau lub sijhawm ntev, tswj kev ua haujlwm txhim khu kev qha txij thaum pib mus txog thaum kaw.
Ntxiv rau cov ntaub ntawv zoo, kev tsim qauv thiab kev tsim khoom kuj tseem ceeb heev. Lub cheeb tsam thiab qhov ntev yuav raug phim raws li qhov dav thiab qhov hnyav ntawm lub qhov cub; Tom qab kev kho tshwj xeeb, qhov chaw du thiab sib npaug, ua kom du thiab tsis hloov pauv ntawm qhov workpiece thaum lub sijhawm thauj mus los. Lub caij no, qhov zoo thermal conductivity ntawm silicon carbide pab kom sib npaug hloov qhov kub hauv lub qhov cub mus rau qhov chaw ntawm qhov workpiece, txo cov qhov tsis zoo uas tshwm sim los ntawm kev cua sov tsis sib xws.
Tsis txhob saib tsis taus tus pas nrig menyuam, nws cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab kev ruaj khov ntawm lub qhov cub. Kev xaiv cov menyuam silicon carbide tuaj yeem txo qhov zaus ntawm lub sijhawm tsis ua haujlwm rau kev hloov cov menyuam, txo cov nqi txij nkawm, xyuas kom meej tias kev tsim khoom tas mus li thiab ruaj khov, zam cov teeb meem ua rau los ntawm kev ua tsis tiav ntawm cov menyuam, thiab pab cov tuam txhab ua tiav cov haujlwm tsim khoom ntau dua.
Tseem muaj cov tswv yim los xaiv thiab siv: cov khoom uas muaj cov noob me me, cov qauv ntom ntom, thiab qhov chaw du yuav tsum tau xaiv; Qhov loj me yuav tsum phim qhov tsim thiab qhov hnyav ntawm lub qhov cub; Kev teeb tsa yuav tsum ua kom muaj coaxiality thiab kev faib tawm lub zog sib npaug; Tsis txhob cia cua txias tshuab rau ntawm cov menyuam kub thaum siv.
Hauv kev xaus, cov menyuam silicon carbide tau dhau los ua qhov tseem ceeb rau kev tsim khoom tas mus li thiab ruaj khov hauv cov qhov cub kub siab vim lawv lub zog tawv hauv kev tiv taus kub siab, kev tiv taus hnav, thiab kev tiv taus thermal shock. Kev xaiv qhov yog thiab siv nws zoo tuaj yeem ua rau muaj kev tsim khoom zoo dua thiab cov khoom ruaj khov dua.
