Lub luag haujlwm tseem ceeb ntawm rwb thaiv tsev bricks yog ua kom sov thiab txo cov cua sov. Rwb thaiv tsev bricks feem ntau tsis ncaj qha mus cuag cov nplaim taws, thiab firebrick feem ntau nyob rau hauv kev sib cuag nrog cov nplaim taws. Firebricks feem ntau yog siv los tiv thaiv cov nplaim ntawm roasted. Nws feem ntau muab faib ua ob hom, uas yog cov khoom siv tsis muaj qhov tsis zoo thiab cov khoom siv refractory zoo li qub.
Unshaped Refractory Khoom
Cov khoom siv castables refractory yog cov hmoov sib xyaw ua ke uas muaj ntau yam sib xyaw los yog sib sau ua ke thiab ib lossis ntau qhov sib khi. Kev siv yuav tsum tau tov nrog ib los yog ntau tshaj cov kua, muaj zog fluidity.
Cov khoom zoo li Refractory
Nyob rau hauv ib txwm muaj, cov duab ntawm refractory bricks muaj tus qauv loj, kuj tuaj yeem kho raws li cov neeg siv khoom xav tau.
Lub ntsiab sib txawv ntawm rwb thaiv tsev cib & Firebricks
1. Kev ua haujlwm rwb thaiv tsev
Lub thermal conductivity ntawm rwb thaiv tsev bricks feem ntau yog 0.2-0.4 (qhov nruab nrab kub 350 ± 25 ° C) w / mk, thiab thermal conductivity ntawm firebrick yog siab tshaj 1.0 (qhov nruab nrab kub 350 ± 25 ° C) w / mk Yog li ntawd, thermal rwb thaiv tsev. kev ua tau zoo ntawm rwb thaiv tsev cib yog qhov zoo dua li qhov hluav taws kub cib.
2. Refractoriness
Lub refractoriness ntawm insulating cib feem ntau qis dua 1400 degrees, thiab refractoriness ntawm cov cib refractory yog siab tshaj 1400 degrees.
3. Ceev ceev
Rwb thaiv tsev cib yog cov khoom siv rwb thaiv tsev, qhov ntom ntawm rwb thaiv tsev cib feem ntau yog 0.8-1.0g / cm3 thiab qhov ceev ntawm cov cib refractory yog qhov siab tshaj 2.0g / cm3.
Xaus
Nyob rau hauv cov ntsiab lus, lub refractory cib muaj lub zog txhua yam, lub neej ntev kev pab cuam, zoo tshuaj stability, tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv nrog cov khoom thiab zoo kub kuj, thiab lub siab tshaj plaws kub resistant kub yuav ncav cuag 1900 ° C. Refractory bricks yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv high-low kub hloov pauv hloov pauv, hloov pauv, hydrogenation converters, desulfurization tso tsheb hlau luam, thiab methanation furnaces ntawm chemical fertilizer nroj tsuag los ua lub luag hauj lwm hauv dispersing gas kua, txhawb, npog, thiab tiv thaiv catalysts. Hluav taws kub refractory cib kuj tseem siv tau rau hauv qhov cub kub thiab cov khoom siv hluav taws xob hloov pauv hauv kev lag luam steel.
Firebricks muaj qhov zoo ntawm cov kev kub ceev, siab zog, coj kuj, zoo xeb kuj, tsis tshua muaj thermal expansion coefficient, siab sib tsoo efficiency, tsis muaj suab nrov, ntev kev pab cuam lub neej, thiab uas tsis yog-contaminating cov ntaub ntawv. Nws yog qhov zoo sib tsoo nruab nrab uas haum rau ntau yam sib tsoo tshuab.
Refractory bricks thiab rwb thaiv tsev bricks yog txawv heev, lawv cov kev siv ntawm ib puag ncig, Scope thiab lub luag hauj lwm tsis zoo ib yam. Cov ntaub ntawv sib txawv yuav raug siv nyob rau hauv qhov chaw sib txawv. Thaum yuav khoom, peb yuav tsum txiav txim siab seb cov khoom siv refractory zoo li cas rau peb tus kheej siv raws li peb qhov xwm txheej.
