Hauv kev tsim cov ceramics, metallurgy, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam, kilns yog cov cuab yeej tseem ceeb, thiab cov kab kiln uas txhawb cov qauv sab hauv ntawm kilns thiab dais qhov kub thiab txias loads tuaj yeem hu ua "skeleton" ntawm kilns. Lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm kev nyab xeeb thiab kev pabcuam lub neej ntawm kilns. Ntawm ntau cov ntaub ntawv ncej, silicon carbide (SiC) kiln pillars tau maj mam dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam kub kub vim lawv qhov kev hloov pauv tau zoo, ntsiag to tiv thaiv kev ua haujlwm ruaj khov ntawm kilns.
Ntau tus neeg yuav muaj kev nkag siab tsis meej txogsilicon carbide kab, tab sis lawv tuaj yeem nkag siab tias yog "kev txhawb nqa nyuaj" hauv cov kilns. Silicon carbide nws tus kheej yog cov khoom siv tsis muaj zog inorganic non-metallic uas ua ke nrog kev kub siab ua haujlwm ntawm ceramics nrog lub zog muaj zog ze rau cov hlau. Nws yog ib txwm yoog mus rau qhov chaw huab cua hauv cov kilns, thiab txhua kab ua los ntawm nws ib txwm muaj qhov zoo ntawm kev cuam tshuam nrog kub thiab hnyav.
Ua ntej, qhov tseem ceeb ntawm kev sib tw ntawm silicon carbide kiln kab yog nyob rau hauv lawv qhov tshwj xeeb tsis kam mus rau qhov kub thiab txias. Thaum lub sijhawm ua haujlwm ntawm qhov cub, qhov kub thiab txias sab hauv tuaj yeem ncav cuag ntau pua lossis ntau txhiab degrees Celsius, thiab qhov kub thiab txias hloov pauv thaum lub sijhawm cua sov thiab cua txias. Cov khoom siv zoo ib yam yog qhov ua rau tawg thiab deformation vim thermal expansion thiab contraction nyob rau hauv ib puag ncig no, ua rau cov qauv tsis ruaj khov. Lub thermal stability ntawm cov khoom siv silicon carbide yog qhov zoo heev, uas tuaj yeem tiv taus lub sijhawm ntev ntawm kev kub kub thiab tiv taus qhov cuam tshuam ntawm kev hloov pauv kub. Txawm tias nyob rau hauv qhov rov ua kom txias thiab kub, nws tuaj yeem tswj cov qauv kev ncaj ncees thiab tsis yooj yim puas, muab kev txhawb nqa tas mus li thiab ruaj khov rau qhov cub.
Thib ob, nws lub peev xwm thauj khoom zoo heev ua rau nws tsis tu ncua nqa lub nra hnyav. Cov qauv sab hauv ntawm lub kiln thiab lub peev xwm thauj khoom ntawm cov ntaub ntawv yuav tsim kom muaj kev thauj khoom tas mus li ntawm cov kab. Cov khoom siv zoo ib yam uas nqa cov khoom hnyav rau lub sijhawm ntev yuav muaj kev khoov, tawg, thiab lwm yam teeb meem, cuam tshuam rau kev ua haujlwm ntawm lub qhov cub. Cov khoom siv silicon carbide muaj siab hardness, ntom qauv, thiab txhua yam muaj zog ntau tshaj li cov khoom siv ceramics thiab hlau. Nws tuaj yeem yooj yim dais ntau yam hauv lub qhov cub, thiab txawm tias nyob rau hauv qhov kub thiab txias thiab hnyav load puag ncig rau lub sijhawm ntev, nws tuaj yeem tuav ruaj khov thiab tsis txhob muaj kev phom sij los ntawm cov kabmob tsis txaus.
Tsis tas li ntawd, zoo heev corrosion kuj tseem tso cai rau silicon carbide kiln kab kom hloov mus rau ntau txoj haujlwm ua haujlwm. Thaum lub sij hawm tsim cov kilns nyob rau hauv ib co industries, corrosive gases los yog plua plav uas muaj kua qaub thiab alkali yog generated. Cov khoom siv zoo ib yam uas raug rau cov xov xwm ntev ntev yuav maj mam corrode, ua rau txo qis zog thiab lub neej ua haujlwm luv. Silicon carbide nws tus kheej muaj cov tshuaj ruaj khov thiab tuaj yeem tiv thaiv kev yaig ntawm corrosive media xws li acid thiab alkali. Txawm tias nyob rau hauv ib puag ncig hnyav corrosive, nws tuaj yeem tswj kev ua haujlwm ruaj khov yam tsis muaj kev hloov ntau zaus, txo cov nqi kho khoom rau cov lag luam.
Rau cov lag luam, kev ua haujlwm ruaj khov ntawm cov kilns ncaj qha cuam tshuam rau kev tsim khoom thiab kev tswj hwm tus nqi, thiab xaiv cov kab hluav taws xob txhim khu kev qha yog qhov tseem ceeb. Silicon carbide kiln kem, nrog rau lawv ntau yam zoo ntawm kub tsis kam, thermal poob siab kuj, muaj zog load-bearing muaj peev xwm, thiab corrosion kuj, zoo kawg nkaus ua tau raws li cov kev xav tau ntawm industrial kilns. Lawv tuaj yeem ua kom muaj kev nyab xeeb ntawm cov kilns, txuas ntxiv lub neej kev pabcuam ntawm cov cuab yeej siv, txo kev tu ntau zaus, thiab dhau los ua kev txhawb nqa zoo rau cov lag luam los txhim kho kev ruaj khov.
Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv kev ntseeg siab thiab ua haujlwm ntev hauv kev tsim khoom, daim ntawv thov scenarios ntawm cov ntaub ntawv silicon carbide kuj tseem nthuav dav. Thiab cov kab ntawm silicon carbide kilns yuav txuas ntxiv ua "tus ncej saum toj kawg nkaus", muab cov khoom txhawb nqa rau ntau qhov kub-kub kev lag luam kilns thiab pab cov lag luam ua tau zoo thiab ruaj khov thiab ua haujlwm.
