Lub luag haujlwm tseem ceeb ntawm cov cib rwb thaiv tsev yog khaws cov cua sov thiab txo cov cua sov poob. Cov cib rwb thaiv tsev feem ntau tsis sib cuag ncaj qha nrog nplaim taws, thiab cov cib hluav taws feem ntau sib cuag ncaj qha nrog nplaim taws. Cov cib hluav taws feem ntau yog siv los tiv taus cov nplaim taws ntawm cov khoom ci. Nws feem ntau muab faib ua ob hom, uas yog cov khoom siv refractory tsis paub meej thiab cov khoom siv refractory zoo li tus.
Cov Khoom Siv Refractory Tsis Muaj Puab
Cov khoom siv refractory castables yog cov hmoov sib xyaw ua ke uas muaj ntau yam aggregates lossis aggregates thiab ib lossis ntau cov binders. Kev siv yuav tsum tau sib xyaw nrog ib lossis ntau cov kua, nrog cov kua dej muaj zog.
Cov Khoom Siv Refractory Zoo Li Cas
Hauv cov xwm txheej ib txwm muaj, cov duab ntawm cov cib refractory muaj qhov loj me, kuj tseem tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Qhov Txawv Tseem Ceeb Ntawm Cov Pob Zeb Rwb Thaiv Tsev & Cov Pob Zeb Hluav Taws
1. Kev Ua Haujlwm Rwb Thaiv Tsev
Qhov thermal conductivity ntawm cov cib rwb thaiv tsev feem ntau yog 0.2-0.4 (qhov nruab nrab kub 350 ± 25 ° C) w / mk, thiab qhov thermal conductivity ntawm firebrick yog siab dua 1.0 (qhov nruab nrab kub 350 ± 25 ° C) w / mk Yog li ntawd, qhov kev ua tau zoo ntawm kev rwb thaiv tsev thermal ntawm cov cib rwb thaiv tsev zoo dua li ntawm cov cib hluav taws.
2. Kev ua kom tsis kub
Qhov refractoriness ntawm cov cib insulating feem ntau yog qis dua 1400 degrees, thiab qhov refractoriness ntawm cov cib refractory yog siab dua 1400 degrees.
3. Qhov Ceev
Cov cib rwb thaiv tsev yog cov khoom siv rwb thaiv tsev sib dua, qhov ceev ntawm cov cib rwb thaiv tsev feem ntau yog 0.8-1.0g / cm3 thiab qhov ceev ntawm cov cib refractory yog qhov siab dua 2.0g / cm3.
Xaus lus
Hauv kev xaus, cov cib refractory muaj lub zog siab, lub neej ntev, kev ruaj khov tshuaj lom neeg zoo, tsis muaj tshuaj lom neeg nrog cov khoom siv thiab tiv taus kub zoo, thiab qhov kub siab tshaj plaws uas tiv taus kub tuaj yeem ncav cuag 1900 ° C. Cov cib refractory yog qhov tsim nyog tshwj xeeb rau kev siv hauv cov hloov pauv kub siab-qis, cov hloov pauv reformers, cov hloov pauv hydrogenation, cov tank desulfurization, thiab cov cub tawg methanation ntawm cov nroj tsuag tshuaj chiv kom ua lub luag haujlwm hauv kev faib cov kua roj, txhawb nqa, npog, thiab tiv thaiv cov catalysts. Cov cib refractory hluav taws kuj tseem siv tau rau hauv cov qhov cub kub thiab cov khoom siv hloov pauv cua sov hauv kev lag luam hlau.
Cov cib hluav taws muaj qhov zoo ntawm qhov ceev ceev, lub zog siab, tiv taus kev hnav, tiv taus corrosion zoo, coefficient nthuav dav thermal qis, kev sib tsoo zoo, suab nrov qis, lub neej ntev, thiab cov ntaub ntawv tsis muaj kuab paug. Nws yog ib qho khoom siv sib tsoo zoo uas haum rau ntau yam tshuab sib tsoo.
Cov cib refractory thiab cov cib rwb thaiv tsev sib txawv heev, lawv siv rau ib puag ncig, qhov ntau thiab tsawg thiab lub luag haujlwm tsis zoo ib yam. Cov ntaub ntawv sib txawv yuav siv rau ntau qhov chaw sib txawv. Thaum yuav cov ntaub ntawv, peb yuav tsum txiav txim siab seb hom ntaub ntawv refractory twg haum rau peb tus kheej siv raws li peb qhov xwm txheej tiag tiag.
