CEMENT COTARCY colent ua haujlwm nyob rau hauv cov neeg kho tshuab huab, thermal, thiab cov khoom siv tsis sib xws
Tsim nyog tsim qauv thiab installation ntawm refractory thaiv kom ntseeg tau tias cov camneable tseem txuas rau cov plhaub hlau thaum tso cai tswj tau cov khoom lag luam phem.
Refractory thauj togtau siv dav hauv Refractory castables. Cov hlau hluav taws tuaj hauv cov duab xws li Y, V, thiab L, nrog Round Ross {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} seem thiab lwm yam kev teeb tsa. Daim duab 1 qhia tau ib qho y - zoo li lub nkoj thauj tog rau nkoj thiab kev nthuav dav sib luag siv rau ib lub phab ntsa ntsug.
Ib kawg ntawm lub thauj tog rau nkoj yog welded rau lub plhaub, thiab lwm qhov kawg yog muab tso rau hauv cov ob sab phlu. Anchor txuas lub plhaub thiab hauv ob sab hauv mus rau ib chav tsev, tiv thaiv cov Kiln phab ntsa los ntawm kev thab plaub lossis tsaus muag. However, when heated, metal oxidizes and expands, exerting significant compressive stress on the refractory material. Lub thermal nthuav coefficients ntawm cov hlau thiab refract cov ntaub ntawv txawv txawv. Kev sib koom ua ke tsis txaus ntseeg tuaj yeem ua rau muaj kev ntxhov siab tseem ceeb hauv cov hlau {{}}} Refractory comprosite qauv. Thaum muaj mob hnyav, lub thauj tog rau nkoj tuaj yeem rub tawm lossis cov Castable tuaj yeem ua rau muaj kev puas tsuaj loj heev. Yog li, cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab thaum tsim cov khoom lag luam thauj:
Lub xub pwga pem hauv ntej kawg ntawm cov hlau txawb yuav tsum tau nyob ntawm 2/3 ntawm cov cua sov phab ntsa thickness.
② tog thauj hluav taws xob yuav tsum tau ua cov oxidation zoo tsis kam ntawm kev ua haujlwm kub. Cov lus 1 qhia txog kev sib raug zoo ntawm lub zog thiab qhov kub ntawm ntau yam khoom siv thauj tog anchor.
Cov hlau hluav taws xob yuav tsum tau qhwv nrog daim kab xev lossis pleev xim los tsim cov pob qij txha nthuav dav. Lub taub hau ntawm cov hlau thauj hluav taws yuav tsum tau capped nrog yas kom tiv thaiv kev nthuav dav thiab puas rau lub Castable.
④ Thaum pouring hla thaj chaw loj, ua haujlwm hauv ntu. Txhua ntu yuav tsum yog kwv yees li 1.5 m² loj. Cov pob qij txha nthuav dav yuav tsum muaj nyob hauv nruab nrab ntawm lub nkoj thauj tog rau nkoj.
Feem ntau, qhov kev sib tw ntawm cov hlau hlau yuav tsum yog 1.5 txog 3 zaug kev tsim kho tuab. Cov spacing yuav tsum siab dua rau cov phab ntsa ntsug thiab qis rau sab saum toj phab ntsa. Rooj 2 Qhov piv txwv ntawm kev teeb tsa ntawm cov hlau thauj tog rau ntawm cov hlau thauj tog rau hauv lub nkoj.
Ntsiab Cai ntawm Refractory Thauj Nkoj thiab Tsim Qauv
(1) Thauj Tog Rau Nkoj Txuas Thiab Kev Ua Haujlwm
Anchor spast txiav txim siab li cas cov txheej Castable tuaj yeem tiv taus tus kheej - hnyav thiab cua sov.
Raug spacing nyob rau hauv cub teb nphings:
Kab rov tav plav: 150-250 hli
Ntsug qhov chaw: 200-300 hli
Thauj tog rau hluav taws xob ntom: 12-20 pcs ib square meter (nyob ntawm caj pas tuab)
Anchors yuav tsum tau muab cov qauv staggered kom tsis txhob muaj cov hniav thermal los ntawm kev refractory.
(2) Meem Thicking Thickness thiab Anchor Ntev
Anchor yuav tsum txuas ntxiv kwv yees li 2/3 ntawm lub Castable Thickness- Tsis txhob kov lub ntsej muag kub.
Meem hauv thickness (hli) Pom zoo rau cov tog hluav taws xob ntev (hli) thauj tog rau nkoj hom
50 - {100 60 - - 80 v - hom
100 - {200 100 - 140 y - hom
200 - {300 150}} - 200 corrugated lossis u - hom
Qhov no ua kom pom tseeb tias lub thauj tog rau nkoj txhawb nqa cov kab ntawv tus kheej - qhov hnyav thaum tso cai pub dawb nyob ze qhov chaw kub.
(3) Cov ntaub ntawv thauj tog rau nkoj rau cov CEMENT lub qhov ncauj
Teb chaws cub ua haujlwm hauv oxidizing thiab qee zaum alkali - cov ntxhib cov cua.
Yog li ntawd, cov khoom siv thauj tog rau nkoj yuav tsum tawm tsam oxidation, ntsuas thiab tshuaj tua rog.
Cov khoom siv Max. Kub (degree) hais
Stainless hlau 310s tsawg dua lossis sib npaug rau 1100 tus qauv khoom rau hauv lub cev
AISI 253MA tsawg dua lossis sib npaug rau 1200 siab creep tsis kam thiab thermal ruaj khov
Inconel 601/625 tsawg dua lossis sib npaug rau 1250 zoo rau cov cheeb tsam burner thiab hloov chaw
RA330 tsawg dua los yog sib npaug rau 1200 rau ntev- ntu sij hawm cycling thiab kub ntsej muag
Refractory thauj tog rau kev teeb tsa kev teeb tsa
Kauj ruam 1: Layout Npav
Marge thauj tog rau nkoj rau tog raws li kev pom zoo tsim qauv kos duab.
Ua kom muaj kev sib nrug ntawm kab rov tav thiab ntsug.
Nco ntsoov tias cov thawj thauj me me pib ua tsawg kawg 50 hli saum toj no Kiln plhaub hauv qab kom tiv thaiv cov cua sov.
Kauj ruam 2: VUAM NKAUS RAUG RAU LUB HNIAV
Ntxuav cov hlau plhaub saum npoo kom tshem tawm cov xeb thiab nplai.
Siv Tig lossis Mig vuam rau cov hlau stainless me.
Vuam kaum sab xis yuav tsum yog 90℃± 5℃rau lub plhaub nto.
Txav deb - cua sov lub tog anchor puag kom tiv thaiv brittleness.
Siv ceramic ferrules thaum thov cov stud -} vuam cov tswv yim.
Kauj ruam 3: Cov kev txiav txim siab thiab qhov tob
Txheeb xyuas tog tog tog neeg no projection ntev ua ntej muab cov refractory.
Anchors yuav tsum tsis txhob kov lossis nkag mus rau qhov kub kub - Lub ntsej muag rectractory.
Tswj hwm kev sib luag rau kev thauj khoom ntxiv.
