Lub thickness ntawm cov cam nyob rau sab hauv ntawm cov tshuaj teb teb lub tog raj kheej teb chawsstary tsis yog 250 hli. Cov kab hauv qab no suav nrog tus naj npawb ntawm cov acidic lossis nruab nrab ntawm lub nkoj loj loj. Ib tug xov tooj ntawm tusyees faib cov hlau thauj hluav taws xob yog tsau rau sab hauv lub tog raj kheej ntawm ob tog ntawm lub pob zeb hauv ob tog Lub acid-alkali-resistant siab cas-zog castable tau txuas nrog lub tog raj kheej raws li tag nrho cov tog thauj tog rau nkoj cib thiab hlau anchors.
Lub ntsiab lus tseem ceeb ntawm kev puas tsuaj rau cov tshuaj ntxuav cov tshuaj ntxuav cov khoom siv hluav taws xob, thiab cov tshuaj lom neeg muaj zog, uas tuaj yeem zam cov khoom siv kub tsis zoo, uas tuaj yeem zam cov khoom siv kub tsis zoo, uas tuaj yeem zam cov khoom siv kub me los ntawm kev ua kom huv si mus rau Kiln.
Cov tshuaj ntxuav cov tshuaj pleev cov khoom siv tau siv Amorphhou Castables nrog cov txiaj ntsig zoo thiab kev tsim kho tau zoo, tsim kev nyab xeeb, thiab tus nqi qis. Cov refractory castables uas ua ke ntawm lub teeb yuag, cov khoom siv kub kom tsis txhob tsuas yog txo qis kev ua haujlwm ntawm lub neej ntawm cov kiln, tab sis kuj txo tus nqi ua haujlwm.

Refractory ntawm lub teb chaws cub
1: Xaiv cov ntaub ntawv refractory rau hauv ob sab ntawm cov tshuaj av teb lub zog
(1) Lub cua sov ntawm cov tshuaj teb cog qoob loo yog siab. Kev ua haujlwm kub yog 1100 ~ 1450 degree, uas yog lub cub tawg nrog qhov kub siab ua haujlwm kub. Hauv kev ua haujlwm qee zaus, lub cua sov sov yuav ncav 1600 degree lossis siab dua.
(2) Muaj ntau ntau cov kev ua kom haum xeeb xws li H2S, H2S, yog li ntawd, yog li ntawd, So2 thiab S Vapor nyob rau hauv lub cub hluavtaws ntawm tshuaj ntxuav kiln. H2S tau txo cov khoom, uas imposes txwv tsis pub muaj qee cov Cheebtsam impurity hauv cov ntaub ntawv cub tawg.
(3) Tshuaj Siv Tshuaj Siv Hluav Taws Xob yog cov roj acid roj sib txuas. Tsis muaj cua sov tawm hauv sab hauv lub cub tawg. Ib qho loj loj Yog li ntawd, cov cub hluav taws xob yog yuav tsum tau kom muaj kev co thermal kev co ua hauj.
(4) Tshuaj Siv Tshuaj Hluav Taws Xob Cov Hluav Taws Xob tau ua rau muaj qhov kub thiab txias kom nruj.
2: Xaiv cov khoom siv refractory rau cov ntaub ntawv ntawm cov tshuaj pleev lub tshuab tsiv teb
2.1 Corundum Castable Khoom
Cov khoom siv hauv ob sab ntawm cov kua qaub roj reactor ntawm cov tshuaj ntxuav cov khoom siv tshuab hluav taws xob yog feem ntau ua los ntawm Cornarum Castable phlu. Qhov laj thawj yog lub Corundum Castable phling tsis tsuas yog muaj lub siab refractory kub, tab sis kuj muaj kev coj zoo. Txawm li cas los xij, vim nws cov kev ua kom tsis zoo thermal tiv thaiv, nws yuav muaj teeb meem xws li teeling thiab poob tawm hauv lub sijhawm luv luv.
2.2 High Alumina Cib + Corundum cib tshuab
Cov khoom siv hauv ob sab phlu ntawm cov roj acid roj sib txuas ntawm cov tshuaj muaj cov tshuaj txhuam cov roj av noo noo yog high alumina Cib + Cork cov khoom siv. Nws cov khiab mis pob qij txha yog ib qho ntawm cov kev sib txuas tsis muaj zog tshaj plaws. Vim yog kev puas tsuaj ntawm cov pob txha sib txuas, kev sib tsoo ntawm kev tawm tsam thiab vau ntawm cov masonry feem ntau tshwm sim. Ntawm qhov tod tes, siab alumina cib thiab corundum cib yog qhov nyuaj rau cov txheej txheem thiab chaw tsim khoom, thiab nws yog qhov nqi tshwj xeeb, thiab tus nqi kuj siab.
2.3 cov ntaub ntawv fiber ntau ntxhuav
Cov hlau Fiber Castable muaj cov hluav taws tsis taus zoo thiab tau ua tiav cov txiaj ntsig zoo. Txawm li cas los xij, nyob rau hauv rooj plaub ntawm cov kua qaub cov pa hluav taws xob ua kom sov, cov khoom siv no yog nquag muaj teeb meem xws li agglomeration thiab tob.
2.4 Kev sib xyaw ntawm cov Castable thiab Prefabricated seem
Kev sib xyaw ua ke ntawm cov tshuaj tsuag castable thiab precabricated ntu yog cov kev daws teeb meem zoo nrog cov nta tseem ceeb: mus txog {{{{} degree) thiab muaj zog. ② Cov Phab Ntsa Cua Sov yog dai hom, tsis yooj yim rau deform lossis poob tawm. ③ Cov tshuaj rwb thaiv av txheej tau nchuav thiab txheej txheej ua haujlwm yog rammed. Nws tuaj yeem ua rau hauv cov duab (tshwj xeeb tshaj yog hauv cov qauv tshwj xeeb). Nws yog ib qho yooj yim los tsim, thiab nws cov qauv sib txuas ua ke yog ntom thiab khoom, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv, thiab tsis muaj qhov sib txawv hauv phab ntsa kiln. ④ Thaum cov ob sab phlu tau txais kev txhawb nqa los ntawm Anchors, Phab ntsa cua sov tuaj yeem tiv taus tev thiab kev tawm tsam, thiab kev txij nkawm yog yooj yim. ⑤ Cov khoom siv hauv ob sab phlu muaj cov tshuaj tiv thaiv zoo-tev cov khoom thiab yuav tsis muaj teeb meem txawv teb chaws. ⑥ Lub sijhawm ua kom sov yog luv luv, thiab kev tsim kho yog nrawm thiab yig.
Alkali-resistant Refractory castables yog alkali-resistant casables tau npaj nrog txhuas cov ntaub ntawv ua kom sib xyaw ua ke thiab hmoov nplej zom, aluminate xis mas thiab admixtures. Hom ntxhuav no tau muab faib ua cov hom hnyav thiab lub teeb, nrog kev kub siab thiab kub siab thiab ua haujlwm zoo. Nws tau siv nyob rau hauv loj thiab nruab nrab-loj loj Kiln thee thiab lub qhov ncauj thiab lub raj xa khoom thiab cov nyhuv yog qhov zoo. Tsis tas li ntawd, dej iav Cov iav Cuz Refractables kuj yog alkali-resistant thiab tuaj yeem tiv thaiv kev yaig ntawm sodium ntsev melts. Yog li ntawd, nws yog siv nyob rau hauv lub alkali rov qab rhuab ntawm papermaking kev lag luam kom ua tiav cov txiaj ntsig zoo dua.
Kev siv cov ntaub ntawv xws li fused corundum, zirconium corundum, magnesia, chrome ore thiab cov hmoov nplej siab, thiab ci rau 12h los ntsuas alkali tsis kam. Thaum Maas thiab -al2o3 hmoov yog tib yam, cov alkali tsis zoo rau fused Magnesia, chrome ore, fused corundum thiab zirconium corundum; Thaum Soob yog siv raws li aggregate thiab 5% ~ 7% zircon hmoov ntxiv, cov alkali tsis zoo yog qhov zoo tshaj plaws thiab cov qauv yuav luag tsis tau txais tsis muaj qhov zoo. Qhov kev puas tsuaj yog qhov tseem ceeb melting.
Hnyav Alkali-resistant Refractory Siv cov ntaub ntawv xws li Magnesia-alumina spinel thiab bauxite sprinker li refractory aggregates thiab hmoov, thiab ntxiv -al2o3 hmoov; Kev Siv Alkali-resistant Refractory siv cov av nplaum qis Cov kev khi ntawm ob lub castables yog ca -70 Mekali cov neeg sawv cev, Composite Memastures thiab ultras hmoov ntxiv nyob rau tib lub sijhawm.
