Silicon Carbide Microcrystalline Tubes: Qhov Kev daws teeb meem kub-resistant rau cov nroj tsuag cement

Nyob rau hauv qhov kub thiab txias siab thiab muaj kev sib txhuam ntau ntawm kev tsim cov cement, kev ua haujlwm ntawm cov khoom siv thermal txiav txim siab ncaj qha rau kev ua haujlwm zoo, kev nyab xeeb ua haujlwm, thiab kev tswj tus nqi. Raws li lub hauv paus tseem ceeb ntawm thermal, qhov zoo ntawm cov raj thermocouple tiv thaiv thiab cov raj pauv cua sov yog qhov tseem ceeb heev. Niaj hnub no, peb qhia txog cov khoom hloov pauv rau cov nroj tsuag cement thoob ntiaj teb:silicon carbide microcrystalline raj— tsim los kom tiv taus cov xwm txheej hnyav tshaj plaws thiab tsa koj cov cement kom siab dua.

Vim li cas Silicon Carbide Microcrystalline Tubes tseem ceeb rau cov nroj tsuag cement

Kev tsim cov cement muaj cov txheej txheem nyuaj xws li kev siv cov khoom siv raw calcination, clinker sintering, thiab kev sib tsoo cement, qhov twg cov txuas tseem ceeb xws li lub rotary kiln, preheater, thiab cooler ua haujlwm ntawm qhov kub tshaj 1200 ° C. Cov raj hlau lossis ceramic ib txwm muaj feem raug kev puas tsuaj sai, xeb, lossis thermal shock failure, ua rau hloov ntau zaus, tsis tau npaj tseg, thiab nce tus nqi txij nkawm. Cov raj silicon carbide microcrystalline, nrog lawv cov khoom siv tshwj xeeb, daws tau cov teeb meem no zoo kawg nkaus.

Cov Kev Zoo ntawm Peb Cov Silicon Carbide Microcrystalline Tubes

1. Kev Tiv Thaiv Kub Siab Zoo Tshaj Plaws

Peb cov raj silicon carbide microcrystalline muaj qhov kub yaj tshaj 2700 ° C thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub txog li 1600 ° C. Txawm tias nyob rau hauv qhov kub heev ntawm thaj chaw hlawv ntawm lub qhov cub rotary, lawv tseem ua kom muaj kev ruaj khov yam tsis muaj kev hloov pauv lossis tawg. Qhov no ua kom ntseeg tau tias kev ntsuas kub thiab kev ua haujlwm hloov pauv cua sov, tshem tawm qhov kev pheej hmoo ntawm kev ua tsis tiav ntawm cov khoom siv los ntawm kev puas tsuaj kub siab.

2. Kev Hnav Zoo Tshaj Plaws & Kev Tiv Thaiv Corrosion

Kev tsim cov cement tsim cov khoom me me uas ua rau cov khoom sib txhuam (xws li cov hmoov nplej nyoos, clinker, thiab hmoov av) thiab cov pa phem (xws li CO₂, SO₂). Cov khoom siv silicon carbide microcrystalline muaj Mohs hardness ntawm 9.2, thib ob tsuas yog pob zeb diamond, ua rau nws tiv taus kev sib txhuam. Tsis tas li ntawd, nws tsis cuam tshuam rau feem ntau cov kua qaub, alkalis, thiab cov pa phem, tiv thaiv kev puas tsuaj ntawm cov kav dej thiab ua rau lub neej ua haujlwm ntev dua 3-5 zaug piv rau cov khoom ib txwm muaj.

3. Kev Tiv Thaiv Kev Kub Siab Zoo heev

Cov chaw tsim cement feem ntau muaj kev hloov pauv sai sai thaum lub sijhawm pib, kaw, lossis hloov kho qhov hnyav. Cov raj silicon carbide microcrystalline muaj cov coefficient nthuav dav thermal qis thiab muaj zog tiv taus thermal shock, muaj peev xwm tiv taus kev hloov pauv kub sai sai ntawm 800 ° C yam tsis tawg. Cov yam ntxwv no txo ​​​​​​qhov zaus ntawm kev hloov raj vim muaj kev cuam tshuam thermal, txhim kho kev ua haujlwm txuas ntxiv.

4. Kev Ua Haujlwm Kub Siab & Kev Ntsuas Qhov Tseeb

Rau cov raj tiv thaiv thermocouple, kev ntsuas kub kom raug yog qhov tseem ceeb rau kev ua kom zoo dua cov txheej txheem calcination. Cov khoom siv silicon carbide microcrystalline muaj cov thermal conductivity zoo heev, ua kom ntseeg tau tias qhov kub uas thermocouple ntes tau yog sib xws nrog qhov kub tiag tiag ntawm qhov chaw tsim khoom. Qhov no pab cov nroj tsuag cement ua tiav kev tswj hwm qhov tseeb ntawm cov txheej txheem sintering, txhim kho qhov zoo ntawm clinker, thiab txo kev siv hluav taws xob.
