Refractory bricks muaj lub zog txhua yam, lub neej ua haujlwm ntev, tshuaj lom neeg ruaj khov, tsis muaj tshuaj lom neeg cov khoom siv, kev kub siab ua haujlwm, thiab kub tsis kam mus txog 1900 degree C. Nws yog tshwj xeeb tshaj yog tsim rau cov hloov pauv kub thiab tsis tshua muaj siab, hloov kho, hydroconverters, desulfurization tanks thiab methanators hauv cov nroj tsuag chiv. Nws ua lub luag haujlwm hauv dispersing gases thiab kua, txhawb nqa, npog thiab tiv thaiv catalysts.
Refractory bricks tuaj yeem siv rau hauv qhov cub kub kub thiab cov khoom siv hluav taws xob hloov pauv hauv kev lag luam steel. Jinyuan yog lub chaw tsim khoom ntawm refractory cib. Refractory bricks muaj qhov zoo ntawm kev kub siab, muaj zog, tsis tshua muaj cua sov, lub suab ntev, lub neej ntev thiab tsis muaj cov khoom qias neeg. Nws yog haum rau txhua yam ntawm grinders thiab sib tsoo xov xwm. Refractory bricks feem ntau muab faib ua ob hom, uas yog unshaped refractories thiab zoo li tus refractories.
Cov khoom tseem ceeb ntawm cov cib refractory yog feem ntau ntawm cov khoom siv tshuaj, uas ua lub luag haujlwm txiav txim siab hauv kev ua haujlwm kub ntawm cov khoom. Refractory bricks muaj qhov kub thiab txias tsis kam. Yog vim li cas vim li cas ntau cov refractories muaj tib yam los yog lawv tus kheej cov khoom yog nyob ntawm lub ntsiab muaj pes tsawg leeg. Yog li ntawd, txaus mloog yuav tsum tau them rau lub ntsiab Cheebtsam ntawm cov khoom refractory. Feem ntau, cov ntaub ntawv refractory raug cais raws li lawv cov tshuaj muaj pes tsawg leeg. Yuav ua li cas xaiv refractory bricks kom raug.
Ntau cov refractories ntawm tib cov khoom siv ntau dua los yog tsawg dua muab faib ua ntau qib raws li hom thiab cov ntsiab lus ntawm lawv cov khoom tseem ceeb. Lub ntsiab Cheebtsam uas yuav siv tau raws li refractories yog cov uas muaj siab lattice zog, siab melting point los yog siab decomposition kub. Yuav kom txiav txim siab tus nqi ntawm refractory bricks, koj yuav tsum txiav txim siab tus nqi ntawm refractory bricks raws li ntau lawm, lub cev thiab tshuaj ntsuas ntawm hom refractory bricks, thiab lwm yam.
Cov khoom siv refractory muaj kev ua haujlwm
1. Bulk Density: Nyhav ib chav tsev ntim thiab siab ceev qhia tau hais tias zoo compactness thiab siab zog, tab sis thermal conductivity yuav ntau dua.
2. Tshuaj muaj pes tsawg leeg: lub ntsiab muaj pes tsawg leeg txiav txim siab qhov zoo thiab cov yam ntxwv ntawm refractory
3. Pom tseeb porosity: Tsis muaj qhov yuav tsum tau ua, tab sis raws li cov chaw tsim khoom, pom meej porosity yuav tsum tau tswj nruj me ntsis.
4. Load softening kub: tseem hu ua deformation kub ntawm high kub load. Qhov parameter no tseem ceeb heev, nws qhia txog qhov kub thiab txias ntawm cov khoom siv.
5. Thermal shock resistance: Lub peev xwm los tiv thaiv qhov kub hloov pauv sai yam tsis muaj kev puas tsuaj.
6. Compressive zog: muaj peev xwm tiv taus siab dua (qhov kub thiab txias).
