Lub cib refractory yog ib qho thaiv ntawm cov khoom siv nyob rau hauv ob sab phlu ntawm cov chaw tsim khoom, kilns, thiab qhov cub. "Fire cib" yog lo lus siv feem ntau rau refractory cib. Nws yog cov khoom siv tuab heev uas tuaj yeem tiv thaiv ntau dhau ntawm cov cua sov thiab xeb. Raws li tuaj yeem kwv yees los ntawm lub npe, lawv feem ntau yog cov duab cib, tab sis lwm hom thiab cov duab tuaj yeem tsim tau thiab. Fireclay yog cov khoom tseem ceeb ntawm refractory bricks, thiab vitrifying lub fireclay yog feem ntau siv txoj kev tsim. Aluminium oxide yog lwm yam khoom tseem ceeb hauv kev tsim khoom thiab tuaj yeem ua kom siab li 80 feem pua.
Refractory Brick Composition
Refractory bricks feem ntau tuaj nyob rau hauv ob qhov ntau thiab tsawg, uas yog 229x114x76 mm thiab 229x114x64 mm. Txawm li cas los xij, raws li tau hais los saum no, nws muaj peev xwm tsim tau ntau qhov sib txawv thiab cov duab. Refractory bricks yog siv nyob rau hauv ntau qhov sib txawv industries thiab lawv cov compositions hloov raws li qhov no. Piv txwv li, refractory bricks ua nrog silica (silica hluav taws cib) yog siv nyob rau hauv lub steel-ua rauv thiab muaj peev xwm tiv taus kub li 3000 F. Txawm hais tias lawv siv nyob rau hauv qis-kub ib yam nkaus thiab, piv txwv li, refractory cib ua nrog magnesium. oxide yog siv nyob rau hauv cov qhov cub zoo tib yam li hauv ob sab phlu.
Qhov tseem ceeb ntawm Hluav Taws Cib
Silicon carbide refractory bricks yog siv rau incinerators thiab nws muaj peev xwm pom cov liab hluav taws cib nyob rau hauv chimneys thiab qhov cub. Hauv lwm lo lus, refractory cib yog cov khoom siv feem ntau thiab nws muaj pes tsawg leeg tuaj yeem hloov tau raws li qhov xav tau. Tab sis ib yam yog ib qho (thiab yuav tsum tau) rau txhua hom refractory cib: lawv yuav tsum tsis txhob spill thiab tuav lawv lub zog tiv thaiv kub hloov ceev. Nyob rau hauv lwm yam lus, lawv yuav tsum muaj ib tug tsawg thermal conductivity thiab muab lub zog efficiency. Refractory bricks yog ib qho tseem ceeb ntawm kev lag luam refractory thiab lawv tau siv ntau pua xyoo.
