Hauv cov txheej txheem tsim khoom lag luam uas xav tau qhov kub thiab txias heev, xws li kev hlawv ceramic thiab kev ua cov khoom siv semiconductor, cov khoom txhawb nqa hauv lub qhov cub ua lub luag haujlwm tseem ceeb.Silicon carbide kiln ncejyog qhov tseeb xws li "kev txhawb nqa nyuaj" zais rau hauv qhov chaw kub siab, thiab lawv tau dhau los ua cov khoom siv nyiam hauv ntau lub lag luam vim lawv cov khoom tshwj xeeb.
Tej zaum yuav muaj ntau tus neeg xav paub txog vim li cas silicon carbide thiaj raug xaiv tshwj xeeb. Qhov tseeb, cov lus teb yooj yim heev - nws yog qhov tsim nyog rau cov xwm txheej kub siab. Silicon carbide yog cov khoom siv ceramic tshwj xeeb uas tsim los ntawm kev sib xyaw ua ke ntawm cov pa roj carbon thiab silicon. Nws qhov Mohs hardness yog qhov thib ob tsuas yog pob zeb diamond, thiab qhov superhard feature no tso cai rau nws yooj yim tiv taus kev sib txhuam thiab hnav hauv qab qhov kub siab. Qhov tseem ceeb tshaj plaws yog tias nws tuaj yeem nyob ruaj khov hauv cov chaw kub siab tshaj ib txhiab degrees Celsius, tsis zoo li cov hlau uas mos thiab deform, thiab nws tsis raug kev txom nyem los ntawm cov teeb meem xws li tawg lossis chipping. Nws tuaj yeem tswj nws txoj kev sawv ntsug txawm tias tom qab siv ntev.
Ntxiv rau qhov ua tau kub thiab tsis yooj yim hnav, cov ncej silicon carbide kiln muaj ob qho zoo dua. Ua ntej, lawv ua rau pom kev ua tau zoo heev, ua rau muaj kev kub ceev hauv lub kiln thiab ua tiav qhov kev faib tawm kub sib npaug. Qhov no yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom raug hlawv thiab tuaj yeem ua rau lub voj voog ntau lawm luv dua. Qhov thib ob, lawv ruaj khov thiab tuaj yeem tiv taus cov chaw muaj corrosive xws li cov kua qaub thiab alkalis yam tsis raug puas tsuaj, yog li tiv thaiv kev ua qias tuaj ntawm cov khoom uas lawv nqa. Qhov no ua rau lawv tsim nyog rau cov khoom siv ceramics zoo, cov khoom siv hluav taws xob precision, thiab lwm yam xwm txheej tsim khoom uas xav tau kev huv siab.
Piv rau cov ntaub ntawv txhawb nqa ib txwm muaj, cov ncej silicon carbide muaj ob qho tib si lub teeb yuag thiab lub zog siab. Lawv tsis ua rau lub tsheb kiln hnyav dhau, tib lub sijhawm muab kev txhawb nqa ruaj khov rau ntau txheej kev thauj khoom, ua kom zoo dua qhov chaw siv hauv lub kiln. Txawm hais tias nws yog lub qhov cub tunnel, lub qhov cub roller hearth, lossis lub qhov cub shuttle, nws tuaj yeem hloov kho rau ntau hom kiln thiab muab tso rau hauv kev siv yam tsis tas yuav hloov kho nyuaj.
Raws li "tus phab ej tsis pom" hauv kev tsim khoom lag luam, lub silicon carbide kiln pillar muab kev txhawb nqa ruaj khov thiab txhim khu kev qha rau kev ua haujlwm kub siab vim nws qhov kev ua tau zoo heev. Nws tsis tsuas yog txo qhov zaus ntawm kev saib xyuas cov khoom siv thiab kev siv zog ntau lawm, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo thiab kev ua haujlwm zoo, ua rau nws yog qhov tseem ceeb hauv cov xwm txheej ua haujlwm kub siab niaj hnub.
